Answer to Question #191943 in C++ for Rahel Aschalew

Question

Swap the content of two variables without using a third variable.

Answer 1

It can be achieved by two methods one is by Arithmetic method and the other is by Using Bitwise XOR.

I am doing it by using Arithmetic operators-

#include <iostream>
using namespace std; 
  
int main() 
{ 
  int x = 10, y = 50; 


  x = x + y; // x = 60
  y = x - y; // y = 10
  x = x - y; // x = 50
  cout << "After Swapping: x = " << x << ", y = " << y; 
}
