Question

What is the output from the following code 

using System;
class Program
{
    static void ChangeMe(int x)
    {
        x = 5;
        Console.WriteLine("Inside Change() the value is {0}", x);
    }
    static void ChangeMe(out int x)
    {
        //out parameter must be assigned before it leaves the function
        x = 5;
        Console.WriteLine("Inside ChangeMe() the value is {0}", x);
    }
    static void ChangeMe(ref int x)
    {
        x = 5;
        Console.WriteLine("Inside ChangeMe() the value is {0}", x);
    }
    static void Main(string[] args)
    {
        Console.WriteLine("***ref and out Comparison-Demo***");
        //for ref, the variable need to be initialized
        int myVariable3 = 25;
        Console.WriteLine("Inside Main(),before call, the value is {0}",
         myVariable3);
        ChangeMe(myVariable3);
        ChangeMe(ref myVariable3);
        ChangeMe(out myVariable3);
        Console.WriteLine("Inside Main(),after call, the value is {0}",
         myVariable3);
    }
}

Compile time error

Note

We can have either ChangeMe(out myVariable3) or ChangeMe(ref myVariable3) with ChangeMe(myVariable3).

They are not allowed together.

If you comment out ChangeMe(out myVariable3), you can fix the error.
