#include <stdio.h>

int main()

{

      int n1, n2, temp;

      printf("Enter first number: ");

      scanf("%d", &n1);

      printf("Enter second number: ");

      scanf("%d",&n2);

      temp=n1;

      n1 = n2;

      n2=temp;

      printf("\nAfter swapping, firstNumber = %d\n", n1);

      printf("After swapping, secondNumber = %.d", n2);

      return 0;

}
