Question

c++ swap program write

Answer 1

hey there,

There are 3 methods of writing c++ swap programme one is using temporary variables and the other is without using temporary variables and other is using third variable.

Here I am writing program with non temporary variables

let's begin

#include <iostream>
using namespace std;

int main( )
{
int a = 5, b = 10;

cout << "Before swapping." << endl;

cout << "a = " << a << ", b = " << b << endl;
a = a + b;
b = a - b;
a = a - b;
cout << "\nAfter swapping." << endl;
cout << "a = " << a << ", b = " << b << endl;
return 0;
}
