How to swap two variables without using the third variable || C Programming||

what is swapping?

swapping refers to exchanging the values of two variables.

for example if a=1 and b=2.Then swapping is changing value of a to b and b to a.

Here after swapping a=2 and b=1.

By C program too we can swap two values.

I am swapping two variables without using third variable.

 Program to swap:

#include<stdio.h>

void main()

{

int a,b;

printf("\n Enter a and b to swap\n");

scanf("%d%d",&a,&b);

\\Logic

a=a+b;

b=a-b;

a=a-b;

printf("\n Swapped values are \ta=%d\tb=%d",a,b);

}
