Function Swap Reference Parameters
Objetive
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")
Example Code
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);
}
}
