Question

Implement the body of the swap function using the indirection operator


// finish this program so that the values of
// x and y are swapped in main().
#include <iostream>
using namespace std;

void swap(int* first, int* second)
{
    // IMPLEMENT THIS FUNCTION
    // YOUR CODE GOES HERE
}

int main()
{
    int x = 9;
    int y = 2;

    swap(&x, &y);

    cout << "x: " << x << endl;
    cout << "y: " << y << endl;

    // if your program works, it will print:
    // x: 2
    // y: 9
}

Given below is the completed code for the question. Please do rate the answer if it helped. Thank you.

// finish this program so that the values of
// x and y are swapped in main().
#include <iostream>

void swap(int* first, int* second)
{
   int temp = *first;
   *first = *second;
   *second = temp;
  
}

int main()
{
   int x = 9;
   int y = 2;

   swap(&x, &y);

   cout << "x: " << x << endl;
   cout << "y: " << y << endl;

   // if your program works, it will print:
   // x: 2
   // y: 9
}
