C Program to swap two numbers without using third(temporary) variable.

/*C Program to swap two numbers without third variable*/

In C we have two techniques to swap the number

1. Without using third variable
2. Using third variable

1. Without using third variable swap the number:

#include<stdio.h>

#include<conio.h>

void main()

{

    int a, b;

    printf("Enter First number in a = ");

    scanf("%d",&a);

    printf("Enter Second number in b = ");

    scanf("%d",&b);

    a= a+b;

    b=a-b;

    a=a-b;

    printf("\nafter swaping the value of a = %d", a);

    printf("\nafter swaping the value of b = %d", b);

    getch();

}
