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.

Hi Bubble Jade,

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,

Sophia Taj
