Function swap reference parameters


Create a function named "Swap" to swap the values of two integer numbers, which are passed by reference.

An example of use might be:

int x=5, y=3;
Swap(ref x, ref y);
Console.WriteLine("x={0}, y={1}", x, y);
(which should write "x=3, y=5")


public class Main
	public static void Swap(int x, int y)
		int swap;
		swap = x;
		x = y;
		y = swap;

	public static static void main(String[] args)
		int x = 5;
		int y = 3;

		Swap(x, y);

		System.out.printf("x: %1$s , y: %2$s" + "\r\n", x, y);
