Answer / priyanka

It gives the value stored at a particular address

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;
int i=10; and you want to accsess the memory of i you have
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?

#include<stdio.h> int fun(); int i; int main() { while(i) { fun(); main(); } printf("hello \n"); return 0; } int fun() { printf("hi"); } answer is hello.how??wat is tat while(i) mean?
