In this example, You learn about c program to swap two numbers using pointers.

Here you learn to swap two numbers using pointer, You are given two numbers and the task of the program to swap two numbers with pointers and functions.

C Program to Swap Two Numbers using Pointers

#include<stdio.h>
void swap(int *p, int *q);
void main()
{
  int *p,*q,a,b,temp;
  printf("Enter Two Numbers to be Swapped: ");
  scanf("%d %d",&a,&b);
  swap(&a,&b);
}
void swap(int *p,int *q)
{
  int temp;
  temp = *p;
  *p = *q;
  *q = temp;
  printf("Numbers After Swapping are: %d and %d",*p,*q);
}

Output

Enter Two Numbers to be Swapped: 12 -15
Numbers After Swapping are: -15 and 12
