Write a C++ program to swap the values of two variables.

Write a C++ program to swap the values of two variables.

Program Code:

#include<iostream>

using namespace std;

int main()

{

int x;

int y;

int temp;

cout<<"Enter first number : ";

cin>>x;

cout<<endl;

cout<<"Enter second number : ";

cin>>y;

cout<<endl;

temp=x; 

x = y;

y = temp;

cout<<"After swapping these two numbers are : ";

cout<<endl;

cout<<"x = "<< x;

cout<<endl;

cout<<"y = "<< y;

return 0;

}

The program code is tested on www.jdoodle.com

Output:

Enter first number : 10

Enter second number : 20

After swapping these two numbers are : 

x = 20

y = 10
