Error 2 Use of unassigned local variable 'Y'

Question

Again i run into an error i don't mean to bug anyone but I'm getting an error on this code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;

namespace Input_Program
{
    class Program
    {
       private static void Main()
        {

           char Y;
            char N;

           Console.WriteLine("Welcome to my bool program!");
           Console.WriteLine("Input a NON capital y or n when told to.");




            if(Y == 'y')
            {
                Console.WriteLine("Thank you,Please wait.....");
            }
        }
    }
}

Thanks for you answers!

Answer 1

Your variable char Y is not initialized before using. Try to give a default value when declaring.

EDIT It seems that you want the users to input something, and assign it to the variable Y. Try:

Y = Console.ReadKey().KeyChar;

Answer 2

if(Y == 'y')

Y is a local variable which isn't assigned anything. So, you assign it any value before the if statement to make any comparison.

Y = 'a';  // or some character 

Answer 3

You're not setting Y to anything, and you're also not reading anything from the keyboard.

Answer 4

You could explicitly set it to null.

char Y = '<whatever_is_the_default_char>';

That would get rid of the compiler error.

The root cause of the compiler error is that when it goes to compile the if conditional nothing as been assigned to Y. The above is considered an assignment.
