C Program to add two numbers / Integers using Pointers :

PROGRAM: 

#include<stdio.h>

#include<conio.h>

main()

{

   int num1,num2, *p, *q, sum;

   /* *p,*q are integer pointer variables*/

   printf("\n Enter two integers to add: ");

   scanf("%d %d", &num1, &num2);

   p = &num1;   /* &num1 gives the value at address of num1*/

   q = &num2;

   sum = *p + *q;  /* adding the values of two pointer variables*/

   printf("\n Sum of entered numbers is: %d",sum);  /*printing sum*/

   getch();

   return 0;

}

Sample Output: ( using GNU GCC Compiler with Code Blocks IDE )

Enter two integers to add: 15 10

Sum of the entered numbers is: 25
