Another way to swap two numbers without using temporary variable in C Language?

Introduction: In this article i am going to explain with example program How to swap/interchange the value of two numbers without using third variable in C language.

Description: Swapping the value of two numbers in C Language is off course not a difficult task. But how many of us actually know that there are multiple ways to swap the value of two variables in C language. There are a number of ways to swap the value of two numbers in C Language.  In this article I am going to use Multiplication (*) and Division (/) arithmetic operators to help in swapping. In previous article How to swap two numbers in C Language ?  I explained how to swap two numbers using temporary variable and there is also my another article How to swap two numbers without using temporary variable in C Language?  that explains another way to swap two numbers in C Language .

Implementation: let's understand by creating a program to swap the values of two numbers.

#include<stdio.h>

#include<conio.h>

void main()

{

 int a,b;

  clrscr();

 printf("Enter the value of a= ");

 scanf("%d",&a);

 printf("\nEnter the value of b= ");

 scanf("%d",&b);

 printf("\nValue of a before swapping= %d",a);

 printf("\nValue of b before swapping= %d",b);

 a=a*b;

 b=a/b;

 a=a/b;

 printf("\nValue of a after swapping= %d",a);

 printf("\nValue of b after swapping= %d",b);

 getch();

 }

Run the program using ctrl+F9

Output:

Enter the value of a=10

Enter the value of b=20

Value of a before swapping=10

Value of b before swapping=20

Value of a after swapping=20

Value of b after swapping=10
