Data structures and C(Self)
In C language ,declaration of variables is done as follows: <var type> <name of var1> , <name of var2>; For eg: int a,b; Then why can’t we use the declaration for pointers as follows to declare 2 interger pointers: int * a,b; instead we use : int *a, *b; ? This might be a silly doubt but please help me out.
