C Program to Swap Two Numbers Using Pointers

Pointers in C language is a variable that stores/points the address of another variable. In this Program we will swap to variable using pointers.

//C program to swap two numbers using Pointers
#include <stdio.h>
int main()
{
  int x, y, t;

  printf("Enter two integers\n");
  scanf("%d%d", &x, &y);

  printf("Before Swapping \nFirst integer = %d \nSecond integer = %d\n", x, y);

  t = x;
  x = y;
  y = t;

  printf("After Swapping \nFirst integer = %d \nSecond integer = %d\n", x, y);

  return 0;
}
