write a Program to swap the two numbers by using third variable in c++

 

#include<iostream>
using namespace std;
int main()
{
int variable_one = 10;
int variable_two  = 20;
int variable_three;
// print values before swapping
cout<<"Variable_one :"<<variable_one<<endl;
cout<<"Variable_two :"<<variable_two<<endl;
//swap values using third variable
variable_three = variable_one;
variable_one = variable_two;
variable_two = variable_three;
//Print values after swapping
cout<<"Variable_one :"<<variable_one<<endl;
cout<<"Variable_two :"<<variable_two<<endl;
}
