This program performs addition of two numbers using pointers. In our program we have two two integer variables x, y and two pointer variables p and q. Firstly we assign the addresses of x and y to p and q respectively and then assign the sum of x and y to variable sum. Note that & is address of operator and * is value at address operator.

## C programming code

#include <stdio.h> int main() { int first, second, *p, *q, sum; printf("Enter two integers to add\n"); scanf("%d%d", &first, &second); p = &first; q = &second; sum = *p + *q; printf("Sum of entered numbers = %d\n",sum); return 0; }
