As 400 Interview Questions
1. Define a shared access path?
To share the open data path by various programs in a same job.
2. What is the difference between array and a multiple occurrence data structure?
The values stored in array don’t vary. In the other hand, we can store the
Different values in same variables at various stages.
3. What is *INZSR used for?
It is special type of RPG/400 subroutine, which is executed automatically
at beginning of the program. It is a good place to code initializes the variables.
4. How can you execute a command from within an RPG program without calling a CLP program?
By calling QCMDEXC application program interface we can execute a CL command with in an RPG program.
5. What is the purpose of the “N” in the following calculation specification?
If you specify ‘N’ in 53rd position, the record will not be locked if you try to read the locked record. It is a way of avoiding the record lock.
7. How can you check for a records existence without causing and I/O (CHAIN/READ)?

With the help of File Information Data Structure, we can check existence of records in a physical file. The code is described below:
In File description continuation line (IPFK),
with the above code we can check the existence of records in a file without causing I/O operation.
8. Define what a data area is along with a brief example of what it may be used for?
Data area is a storage area to store limited information.
Example: a new and unique customer number is generated whenever a new customer is added to customer master file.
Data area keeps track of last record added and add 1 to it. Through program we can access new customer number.
9. Define what a data queue is along with a brief example of what it may be used for?
Data queues provides communication between programs by calling API’s QSNDDTAQ and QRCVDTAQ along with parameters like data queue name, library in which data queue exists, variable to store the number of characters to be sent, variable to store the information to be sent. We can send the same data queue to the many programs.
10. What is the purpose of the following?
It is a type of initializing the variables in I-spec. and these are further used in C-spec.
11. What is the difference between UDATE and the system date?
UDATE supports two-digit year. The format is *MDY (MMDDYY).

What is Dynamic programming technique

What is Dynamic programming technique
Dynamic Programming:
A DP is an algorithmic technique which is usually based on a recurrent formula and one (or some) starting states. A sub-solution of the problem is constructed from previously found ones. DP solutions have a polynomial complexity which assures a much faster running time than other techniques like backtracking, brute-force etc.
Example Problem:
Given a list of N coins, their values (V1, V2, ... , VN), and the total sum S. Find the minimum number of coins the sum of which is S (we can use as many coins of one type as we want), or report that it's not possible to select coins in such a way that they sum up to S.
For a better understanding let's take this example:
Given coins with values 1, 3, and 5.
And the sum S is set to be 11.
First of all we mark that for state 0 (sum 0) we have found a solution with a minimum number of 0 coins. We then go to sum 1. First, we mark that we haven't yet found a solution for this one (a value of Infinity would be fine). Then we see that only coin 1 is less than or equal to the current sum. Analyzing it, we see that for sum 1-V1= 0 we have a solution with 0 coins. Because we add one coin to this solution, we'll have a solution with 1 coin for sum 1. It's the only solution yet found for this sum. We write (save) it. Then we proceed to the next state - sum 2. We again see that the only coin which is less or equal to this sum is the first coin, having a value of 1. The optimal solution found for sum (2-1) = 1 is coin 1. This coin 1 plus the first coin will sum up to 2, and thus make a sum of 2 with the help of only 2 coins. This is the best and only solution for sum 2. Now we proceed to sum 3. We now have 2 coins which are to be analyzed - first and second one, having values of 1 and 3. Let's see the first one. There exists a solution for sum 2 (3 - 1) and therefore we can construct from it a solution for sum 3 by adding the first coin to it. Because the best solution for sum 2 that we found has 2 coins, the new solution for sum 3 will have 3 coins. Now let's take the second coin with value equal to 3. The sum for which this coin needs to be added to make 3 , is 0. We know that sum 0 is made up of 0 coins. Thus we can make a sum of 3 with only one coin - 3. We see that it's better than the previous found solution for sum 3 , which was composed of 3 coins. We update it and mark it as having only 1 coin. The same we do for sum 4, and get a solution of 2 coins - 1+3. And so on.

What is Constructor in cpp

What is Constructor in cpp
Constructors do not have return type and so they cannot return error codes. How are errors or exceptions handled in constructors? What if the calls that you make in the constructor can actually throw exceptions? How do you let the caller know something bad happened in a constructor?
There are a few ways to do robust error/exception handling in constructors
1. Do as little in the constructor has you can. Then provide an Init() function in the constructor, which does the normal initialization stuff. The user can then call this function after creating an object. The problem here is, its up to the user to actually call the Init() function. The user could potentially miss this step, making this method error prone. However, there are a lot of places where this methodology is used. You are trying to eliminate error handling in the constructor by using this method
2. Another way to do this is by putting the object in a Zombie state. This is one approach you can take especially if you do not have the option of using exceptions. When you go with this option, you will also to do provide a function that will check the state of the object after construction. The downsides to this option is that, its up to the user to do these checks and the users will need to do this every time one attempts to create an object. It's usually always better and cleaner to throw an exception instead. Use the Zombie option as a last resort.
3. The downsides to the above methods can be reduced by making the constructor private or protected, expose a CreateInstance() public method, and do all the error handling here rather than leave it to the user. But sometimes, its not possible to handle all the error conditions in a generic manner and you will need to throw an exception.
4. If an exception is thrown in the constructor, the destructor will not get called. So you need to handle and clean up as much as you can before you leave the constructor. The best way to do this is using the "resource allocation is initialization" technique. I will cover this topic separately in a future post. But the basic idea is to assign resource allocation and cleanup to other objects. Basically, you are trying to get allocation out of the way (indirect) so that you don't have to do it explicitly. When you don't allocate something directly, you don't have to release it either because it will be done by the component or class who deals with it. E.g. If you need to allocate some memory or open up a file, You can use smart objects (smart pointer, auto_ptr, smart file handlers etc..) instead of calling new or fopen directly. When you do this, and if an exception is thrown in your constructor, the smart objects will automatically release the resources it acquired, as the stack unwinds. If you do not use the "resource allocation is initialization" technique, the user will need to wrap the statements in try/catch block and rethrow after cleaning up the mess, something like what the finally block does in Java or C#. Although this works in theory, it's up to the user to make this work and it also always a source of errors and bugs (esp. memory and handle leaks) and is messy
As you have seen, there is no "one size fits all" rule to do error/exception handling in constructors. I have listed the most commonly used methods and one of these should work most of the time.

Swap variables without additional space

Swap variables without additional space
Swapping variables is a very common operation used it tons of algorithms like sorting etc. The most common and obvious technique is using of a temporary variable to swap values between two variables
void swap(int &i, int &j)
int temp = i;
i = j;
j = temp;
Instead of writing a separate function for each data type, you could write a MACRO or templatize the function.
Swapping without using a temporary variable is an age old trick and there are a few ways to do this. You could use of the basic arithmetic operations like +,-,/,*
1: void swap(int &i, int &j)
2: {
3: i=i+j;
4: j=i-j;
5: i=i-j;
6: }
The technique involves storing the sum of variables in one of them and then extracting it back by subtracting the other number. There are different variants to this technique. E.g, instead of starting by storing the sum, you could store the difference, product or the quotient. The last two could lead you to round-off and integer division errors. However all of them have one fundamental flaw. Its in line 3, and the issue is that this could lead to an overflow error.
This is another technique the gets you around these issues; the XOR Swapping technique
void swap(int &i, int &j)
i = i ^ j;
j = j ^ i;
i = i ^ j;
This is an elegant technique and should work well with any primitive data type and you could write a simple MACRO like
#define SWAP(i, j) (((i) ^= (j)), ((j) ^= (i)), ((i) ^= (j)))
Although, the XOR technique gets rid of the other issues like overflow and round off errors that we encountered in the previous technique, the lands in into yet another issues; This does not work when you try to swap the same memory location. However if can get around this by a simple 'if' check or a more elegant OR check like
#define SWAP(i, j) ( (i==j) ((i) ^= (j)), ((j) ^= (i)), ((i) ^= (j)))
The first OR condition (i == j) is checked before the actual SWAP. (You do not need a SWAP if the both memory locations hold the same data)

What is copyconstructure in cpp

What is copyconstructure in cpp
As the name suggests, a copy constructor is called whenever an object is copied. This happens in the following cases:
* When an object is create from another object during initialization (Class a = b)
* When an object is created from another object as a parameter to a constructor (Class a(b))
* When an object is passed by value as an argument to a function (function(Class a))
* When an object is return from a function (Class a; ... return a;)
* When an exception is thrown using this object type (Class a; .... throw a;)
Whenever an object copying scenario like the ones above is encountered, the copy constructor is invoked. A copy constructor can be either user defined or compiler defined. If the user does not define a copy constructor, then the default compiler defined copy constructor will be invoked during object copy scenarios. The default copy constructor is a bit-by-bit (member wise) copy. But often you will encounter situations where this is not desirable since this is just a shallow copy and sometimes you do not want an exact copy or you may want to do some custom resource management.
Class t1;
Class t2=t1; // Copy Constructor is invoked
Class t3;
t3=t1; // Assignment Operator is invoked
In the Code snippet above, the constructor is invoked twice, during the creation of objects t1 and t3. (Creation of t2 invokes the copy constructor). The destructor is invoked 3 times though. In cases like these, if the constructor allocates memory and the destructor frees it, you will see the t2's destructor will try to delete already deleted memory, if t1 is destroyed before t2 or vice-versa. Meaning, you are hosed. To prevent this, a user defined copy constructor needs to be provided. which doesn't do a simple bit-by-bit but rather assigns memory specifically for the object and does a deep copy if required.
To define a copy constructor for a class T, a constructor of the following format needs to be defined.
Class T

T(const T& t)

You need a reference because if it were T(T t), it would end in a infinite recursion. (Was that an oxymoron?). const because you are not changing the object in the constructor, you are just copying its contents
Some Rules of Thumb:
* Don't write a copy constructor if a bit-by-bit copy works for the class
* If you defined your own copy constructor, it probably because you needed a deep copy or some special resource management, in which case, you will need to release these resources at the end, which means you probably need to define a destructor and you may also want to think of overloading the assignment operator (beware of self-assignment)

Different types of buffer overruns,Buffer over flow

Different types of buffer overruns,Buffer over flow
Buffer Overruns is one of top sources of security issues today.  These are typically caused by trusting input data to a function that is external and is unchecked. Most of the times, this is unintentionally invoked by bad sloppy code. However, when done intentionally by a hacker, this can cause havoc. Some of the most common, buffer overrun prone functions include strcpy, memcpy, strcat etc... In unintentional buffer overruns, this mostly results in writing to memory not owned by your processes address space. In such cases this would end, in an access violation or a core dump, causing the program to be aborted in most cases.  However, these buffer overruns can be exploited to run arbitrary code on the machine, even code that is injected in by the attacker.
There are different types of buffer overruns.

Static Buffer Overruns: These type of buffer overruns occur, when a buffer that is declared on the stack is overwritten by copying more data than the buffer can hold. It so happens, that the variables (buffer in this case) declared on the stack are located next to the return address of the function's caller. As I mentioned above, this usually occurs when user input is unchecked, e.g. strcat. And because the return address is next to the buffer on the stack, overwriting the buffer, means overwriting the return address, which is what gets executed with the function returns. An attacker can carefully exploit the overrun in such a way the data that is overwriting the return address, is an address of a function that he wants to execute.
Heap Overruns: Like Stack Overruns, Heap overruns can also cause memory and stack corruption. But unlike contrary developer belief, although heap overruns are harder to exploit, they are definitely exploitable.
Array Indexing Errors (Overruns and Underruns): These type of errors are less exploited compared to static buffer overruns. You can think of an array as a block on memory (buffer) that you can index into and then read/'write' from that location. Bad array implementation do not check indices well before access the memory locations. Sloppy code like this can be exploited to run arbitrary code and create havoc. (Well, in some cases you may never ever now that your machine is freely accessible and controlled by the attacker :) ). Again, unlike contrary developer belief, don't be fooled that only memory past the end of the array can be exploited.
Format Strings Exploits: These type of exploits are not exactly buffer overruns, but they lead to the same class of problems. These errors are usually caused in functions that take in variable number of arguments, because there isn't a good way for the function to determine the number of arguments passed into these functions. (printf family in the CRT). The %n type field for printf represents the number of characters successfully written so far to the stream or buffer. This value is stored in the integer whose address is given as the argument. So, this can basically be used to write into memory of the processes address space. But how can an attacker inject such code? The answer lies to the way the sloppy programmer writes code ala printf(input), rather than printf("%s", input). The latter prevent the user from using his own format, since its already defined, unlike the earlier case, where the input can be manipulated to create the format string.

21) Alice and Bob play the following coins-on-a-stack game. 20 coins are stacked one above the other. One of them is a special (gold) coin and the rest are ordinary coins. The goal is to bring the gold coin to the top by repeatedly moving the topmost coin to another position in the stack. Alice starts and the players take turns. A turn consists of moving the coin on the top to a position i below the top coin (0 ≤ i ≤ 20). We will call this an i-move (thus a 0-move implies doing nothing). The proviso is that an i-move cannot be repeated; for example once a player makes a 2-move, on subsequent turns neither player can make a 2-move. If the gold coin happens to be on top when it’s a player’s turn then the player wins the game.
Initially, the gold coinis the third coin from the top. Then
In order to win, Alice’s first move should be a 0-move.
In order to win, Alice’s first move should be a 1-move.
Alice has no winning strategy.

The Health Insurance Portability and Accountability Act of 1996 (HIPAA)
* Protects health insurance coverage for workers and their families when they change or lose their jobs.
* Administrative Simplification provision is composed of four parts, each of which have generated a variety of "rules" promulgated by the Department of Health and Human Services.
The four parts of Administrative Simplification are:
* Standards for Electronic Transactions
* Unique Identifiers Standards
* Security Rule
* Privacy Rule
Standards for Electronic Transactions :
* Electronic Health Transactions includes health claims, health plan eligibility, enrollment and disenrollment, payments for care and health plan premiums, claim status, first injury reports, coordination of benefits, and related transactions.
* In the past, health providers and plans have used many different electronic formats to transact medical claims and related business. Implementing a national standard is intended to result in the use of one format, thereby "simplifying" and improving transactions efficiency nationwide.
* Virtually all health plans must adopt these standards. Providers using non-electronic transactions are not required to adopt the standards for use with commercial healthcare payers. However, electronic transactions are required by Medicare, and all Medicare providers must adopt the standards for these transactions. If they don't, they will have to contract with a clearinghouse to provide translation services.
Unique Identifiers Standards:
In the past, healthcare organizations have used multiple identification formats when conducting business with each other – a confusing, error-prone and costly approach. It is expected that standard identifiers will reduce these problems. The Employer Identifier Standard, published in 2002, adopts an employer's tax ID number or employer identification number (EIN) as the standard for electronic transactions. Final standards for Provider and Health Plan identifiers have not yet been published.
Privacy Rule:
* Give patients new rights to access their medical records, restrict access by others, request changes, and to learn how they have been accessed
* Restrict most disclosures of protected health information to the minimum needed for healthcare treatment and business operations
* Provide that all patients are formally notified of covered entities' privacy practices,
* Enable patients to decide if they will authorize disclosure of their protected health information (PHI) for uses other than treatment or healthcare business operations
* Establish new criminal and civil sanctions for improper use or disclosure of PHI
* Establish new requirements for access to records by researchers and others
* Establish business associate agreements with business partners that safeguard their use and disclosure of PHI.

HIPAA 270/271 Flow:
The Health Plan Employer Data and Information Set (HEDIS®)

A set of standardized performance measures designed to ensure that purchasers and consumers have the information they need to reliably compare the performance of managed health care plans.
The performance measures in HEDIS are related to many significant public health issues such as cancer, heart disease, smoking, asthma and diabetes.
HEDIS also includes a standardized survey of consumers' experiences that evaluates plan performance in areas such as customer service, access to care and claims possessing.
HEDIS is sponsored, supported and maintained by NCQA.

* Point-of-service plans are health benefit arrangements that evolved in response to consumer desire for broader choice in physicians and health care facilities. Health maintenance organizations offer POS plans to give their members a choice of either in-network benefits or out-of-network benefits.
* "In-network" refers to health care professionals and facilities that are members of the health plan's provider network. They are usually listed as "participating providers" in membership materials. Except in special cases, such as emergency treatment, HMOs usually cover care delivered by in-network providers only.
* "Out of network" refers to health care professionals who have no contractual relationship with the health plan. Out-of-pocket costs vary according to how a member chooses to receive care at the "point of service" (hence the name).
Defined Contribution Plan
* Involve employer funding of a fixed (as opposed to variable) dollar amount for health benefits, which employees may then use to purchase benefits from an employer arranged funding mechanism.
* The benefits could either be group benefits packaged and arranged by the employer, or purchased individually by the employees.
Carrier vs. Payer
An insurer; an underwriter of risk that finances health care. Also refers to any organization, which underwrites or administers life, health or other insurance programs. When an employer has a “self-insured” plan, the carrier (such as Aetna or Blue Cross) may not serve as carrier in this case, but may serve only as “third party administrator.
Payer :
The public or private organization that is responsible for payment for health care expenses. Payers may be insurance companies or self-insured employers.
* A federal program that pays for certain health care expenses for people aged 65 or older. Enrolled individuals must pay deductibles and co-payments, but much of their medical costs are covered by the program.
* Medicare is less comprehensive than some other health care programs, but it is an important source of post- retirement health care.
* Medicare is divided into three parts.
* Part A covers hospital bills,
* Part B covers doctor bills, and
* Part C provides the option to choose from a package of health care plans.
* State programs of public assistance to persons regardless of age whose income and resources are insufficient to pay for health care.
* The United States federal government provides matching funds to the state Medicaid programs.
Coordination of Benefits (COB)
* Provision regulating payments to eliminate duplicate coverage when a claimant is covered by multiple group plans. The procedures set forth in a Subscription Agreement to determine which coverage is primary for payment of benefits to Members with duplicate coverage.
* A coordination of benefits, or "nonduplication," clause in either policy prevents double payment by making one insurer the primary payer, and assuring that not more than 100 percent of the cost is covered. Standard rules determine which of two or more plans, each having COB provisions, pays its benefits in full and which becomes the supplementary payer on a claim.
* Also called cross-over

DRG Diagnostic Related Groupings
International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM, ICD-10-CM) - This is the universal coding method used to document the incidence of disease, injury, mortality and illness.
A diagnosis and procedure classification system designed to facilitate collection of uniform and comparable health information.
The ICD-9-CM was issued in 1979. This system is used to group patients into DRGs, prepare hospital and physician billings and prepare cost reports.
Classification of disease by diagnosis codified into six-digit numbers.
Diagnosis Related Groups (DRGs):
An inpatient or hospital classification system used to pay a hospital or other provider for their services and to categorize illness by diagnosis and treatment.
A classification scheme used by Medicare that clusters patients into 468 categories on the basis of patients' illnesses, diseases and medical problems. Groupings of diagnostic categories drawn from the International Classification of Diseases and modified by the presence of a surgical procedure, patient age, presence or absence of significant complications/other relevant criteria.
System involving classification of medical cases and payment to hospitals on the basis of diagnosis.
Common Health Plan Types:
Defined Contribution
A health maintenance organization (HMO) is a health care delivery system that accepts responsibility and financial risk for providing a specified set of health care services to an enrolled membership in exchange for a fixed, prepaid fee from the purchaser (i.e., either the employer, government or an individual.) HMOs build network through contracts with selected physicians or physician groups, hospitals, and other providers who render care for a given population for a discounted fee in anticipation of an increased volume of patients. Those individuals who become members of an HMO (i.e., enrollees) agree to receive care from this contracted network of providers.
Characterized by a PCP, all treatment/referrals thru PCP
A Preferred Provider Organization (PPO) is a group of health care professionals and/or hospitals that contract with an employer or insurance company to provide medical care to a specified group of patients. Participating health care providers exchange discounted services for an increased volume of patients from this group. Insurance companies offer PPOs to give their members a choice of either in-network benefits or out-of-network benefits.
