#include <stdio.h>
main()
{
   int a, b, temp;

   printf("\n Enter the values of a and b: ");
   scanf("%d %d", &a, &b);  // Taking The values of x and y from user
   printf("\n Before Swapping: \n a = %d b = %d \n",a,b);

   temp = a; //temp stores value of a
   a = b;    //a stores b value
   b = temp; //b stores temp value

   printf("\n After Swapping: n a = %d b = %d \n",a,b);
   return 0;
