Answer 1

Since this is your "Main function" it is set to static:

static void Main(string [] args) ....

Because it's static you can only use other static methods unless you create an object or do an object reference. (That's when you use other classes to help you in this program)

So you'll be to make your functions in your main class all static functions before the program can correctly work

Oh, forgot about this.
Thanks so much)
