Program to swap two numbers using pointer in c; Through this tutorial, we will learn how to swap two numbers using pointer in c program.
C Program to Swap Two Numbers using Pointer
#include <stdio.h>
void swapTwo(int *x, int *y)
{
int temp;
temp = *x;
*x = *y;
*y = temp;
}
int main()
{
int num1, num2;
printf("Please Enter the First Value to Swap = ");
scanf("%d", &num1);
printf("Please Enter the Second Value to Swap = ");
scanf("%d", &num2);
printf("\nBefore Swapping: num1 = %d num2 = %d\n", num1, num2);
swapTwo(&num1, &num2);
printf("After Swapping : num1 = %d num2 = %d\n", num1, num2);
}
The output of the above c program; is as follows:
Please Enter the First Value to Swap = 5 Please Enter the Second Value to Swap = 6 Before Swapping: num1 = 5 num2 = 6 After Swapping : num1 = 6 num2 = 5
