C++ Program To Swap Value By Passing Reference

#include <iostream>
using namespace std;
#include <iomanip>
int swap(int &a, int &b)
{
    int temp;
    temp = a;
    a = b;
    b = temp;
    return 0;
}
int main()
{
    int a, b;
    cout << "Enter the value of a and b \n";
    cin >> a >> b;
    swap(a, b);
    cout << "The swapped value of a is " << a << endl
         << "The swapped value of b is " << b;
}

OUTPUT

Enter the value of a and b

60

90

The swapped value of a is 90

The swapped value of b is 60
