Answer Posted / dally
defination is allocating memory to the variable.
but declaration is telling what type of variable it is and
not allocating memory for it.
Ex.int i;
extern int b;
here int i is definition because variable of value is
allocated in memory.
but variable b declared as int variable but memory is not
allocated for this.
float y is defination as compiler allcates memory for it
if you give as extern float y it is declaration
