#include <iostream>
using namespace std;
int main()
{
    int number1, number2;
    cout << "Enter the value for number1 : " << endl; 
    cin >> number1;  //taking first number
    cout << "Enter the value for number2 : " << endl; 
    cin >> number2;  //taking second number
    cout << "You Entered number1 as: " << number1 << " and number2 as: " << number2 << endl;
    int number3;
    number3 = number1; //Swapping two numbers using third variable i.e number3
    number1 = number2;
    number2 = number3;
    cout<<"After Swapping, number1 is : "<<number1<<" number2 is : "<<number2;
    return 0;
}

output :
