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
using System;
public class exercise106
{
public static void Swap(ref int x, ref int y)
{
int swap;
swap = x;
x = y;
y = swap;
}
public static void Main()
{
int x = 5;
int y = 3;
Swap(ref x, ref y);
Console.WriteLine("x: {0} , y: {1}", x, y);
}
}
