SWAPPING TWO NUMBERS WITHOUT USING TEMPORARY VARIABLE

AIM

To write a C program for swapping two numbers without using temporary variable

ALGORITHM

Step 1: Start

Step 2: Read two numbers a,b

Step 3: a←a+b

Step 4: b←a-b

Step 5: a←a-b

Step 6:Print the numbers a,b

Step 7:Stop

PROGRAM

#include<stdio.h>

#include<conio.h>

void main()

{

    int a,b;

    scanf("%d%d",&a,&b);

    printf("Before swapping\na=%d\nb=%d\n",a,b);

    a=a+b;

    b=a-b;

    a=a-b;

    printf("\nAfter swapping\na=%\nb =%d ",a,b);

    getch();

}

RESULT

The C program for swapping two numbers is completed successfully and the output is verified.
