Swapping of two numbers in C++ without using third variable.
#include <iostream>
using namespace std;
int main()
{
//Variable declaration
int number1,number2;
cout<<"Enter your first number to swap ";
cin>>number1;
cout<<"Enter your second number to swap ";
cin>>number2;
cout<<"Before swaping the numbers are "<<number1<<" and "<<number2<<endl;
// swaping of Variable using airthmetic operators
number1 = number1 + number2;
number2 = number1 - number2;
number1 = number1 - number2;
cout<<"After swaping the numbers are "<<number1<<" and "<<number2<<endl;
return 0;
}Output
Enter your first number to swap 4
Enter your second number to swap 6
Before swaping the numbers are 4 and 6
After swaping the numbers are 6 and 4
