• Use XOR operator to swap two variables without using third variable

• Assign the XOR of both variables to the first variable

• Assign the XOR of the first...read more

#include<iostream>

using namespace std;

int main()

{

int a=0,b=1;

a=a^b; //1

b=a^b; //0

cout<<a<<b;

return 0;

}

//using XOR operator we can swap two variables without using third variable!
