How can we right a program in which we swap/interchange just two integers, remember that we use only two variables?

## Swap/interchange variable c++ program question.

Normally anybody can swap any variable. We can use any programming Language to do that job. If we use C language.

First We need to declare a three variable like int x,y,temp;

Suppose x=10;

y=5;

temp=0;

When we swap it x comers value 5, and y comes Value 10.

Do it as x= temp; /————— the value of x comes in temp now 10.

X=y; / —————–Value of y comes x now.

y= temp; / —————–value of temp means value of x previous 10 comes in y now.

Result : value of x=5;

Value of y=10.

temp=0.

Its easy in c programming. Anybody can do as easily.

## Swap/interchange variable c++ program question.

Please find the below code to interchange / swap two variables in c++.

#include <iostream.h>

int main()
{
int a=3,b=4;

count<<" n Original value of a = "<<a<<" t b = "<<b;

a = a + b;
b = a – b;
a = a – b;

count<<" n Interchange value of a = "<<a<<" t b = "<<b;

return 0;
}

Thanks,

I've tried your program Sophia in interchanging two variables and looks like you've got it. Thanks! Very helpful indeed.

Thanks Sophia and techyv.
