Answer / rafiya

Variable is a name given to the memory location of the specified data type.
Pointers are the variables which are capable of storing another variable's address.

Answer / nibedita

Pointers will store the variable address and normal variable
will store the variable value. But if you will declare int *p;

to write p=&i; But i can access directly the memory adress
of variable through printf("%d",&i); Then wht is the
difference between pointer and normal variable?
