swap function

[G60iz8AR]

How to find the swap function ?
#include <iostream>
#include <string>
using namespace std;

// YOU WRITE THe SWAP FUNCTION PROTOTYPE HERE


int main ()
{
int x,y;
cout << "Enter a two small positive numbers: ";
cin >> x >> y;
cout << "Before swap: x=" << x << " y= " << y << endl;
// swap( x , y );
cout << "After swap: x=" << x << " y= " << y << endl;

return 0;
}


// YOU WRITE THe SWAP FUNCTION BELOW

um...

int y(1), x(0);
swap(x, y); //x and y are swapped... 

Mabey you want to rephrase?
