How to Swap two Integers in C++

Structure of the Problem Requirements 

In this Problem we Swap the two integers in C++ Program. We can also change the Value of a Variable using Pointers in C++ but here we use three Variables two Swap the Value of two Integers . The First two Variables Hold their real values while the Third Variable is use to Swap their Variables.

Source Code

#include <iostream>         

using namespace std;

/* Programme to Swap the Value of two Integers */

int main()

 {

  int number1 = 0;   // Intilize a variable for number 1

  int number2 = 0; // Intilize a variable for number 2

  int swap = 0; // Intilize a variable for swaping the value

  cout<<endl<<"************ VALUE SWAP ***************"<<endl;

  cout<<endl<<"Enter Number_1 : ";

  cin>>number1; // Reccieveing from the Keybord

  cout<<endl<<"Enter Number_2 : ";

  cin>>number2; //Reccieveing from the Keybord

  swap = number1; // in Variable Swap save the value of number 1

  number1 = number2; // in Number 1 value save the value of number 2

  number2 = swap; // in number 2 save the value of Swap and in swap there is value of Number 1

  cout<<endl<<endl<<"After Swap Number_1 : "<<number1<<endl; // Display the number 1 after Swapping

  cout<<endl<<endl<<"After Swap Number_2 : "<<number2<<endl; //// Display the number 1 after Swapping

 return 0;

}

Output of the Program

Both Number's Swapping there Value
