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
YOU CAN GET A HUGE LIST OF C PROGRAMS ON www.vitedu.in with output and in downloadable format.... Have a Look at it...
