Declaration and the definition of a variable difference?

Declaration and the definition of a variable difference?
The definition is the one that actually allocates space, and provides an initialization value, if any.
There can be many declarations, but there must be exactly one definition. A definition tells the compiler to set aside storage for the variable. A declaration makes the variable known to parts of the program that may wish to use it. A variable might be defined and declared in the same statement.
