C Program to Swap Values of Two Variables

Solution:

I have used Code:: Blocks compiler for debugging purpose. But you can use any C programming language compiler as per your availability.

#include<stdio.h>
int main()
{
     int num1;
     int num2;
     int temp;

     printf("Type value of number 1 : ");
     scanf("%d",&num1);

     printf("\nType value of number 2 : ");
     scanf("%d",&num2);

     temp = num1;
     num1 = num2;
     num2 = temp;

     printf("After swapping values \n");
     printf("number 1 : %d",num1);
     printf("\nnumber 2 : %d",num2);
     return 0;
}

Result:

Type value of number 1 : 5

Type value of number 2 : 3

After swapping values 

number 1 : 3

number 2 : 5
