what's the problem you're having?

CheetahOP•16mo ago

im trying to make what the user types in an interger so i can do like == stuff but it dont work :( and i cant figure out

SinFluxx•16mo ago

what do you mean by "dont work" you're receiving an error?

CheetahOP•16mo ago

when i use variable "Guess" it says i cant use == with Int and String and when i use IntGuess as variable and try to print it nothing comes up wait

Sorry @cheetahsflame your message contained blocked content and has been removed!

CheetahOP•16mo ago

wait i might be dumb hold on do i use IntGuess or Guess as int variable here

Pobiega•16mo ago

Guess is declared as a string and can thus only ever hold strings IntGuess is declared as an int.

CheetahOP•16mo ago

yea ok good thats what i thought but here its suppose to say a number and if i write the number it says good job but nothing happens so im wondering if IntGuess thing isnt working

Pobiega•16mo ago

how about debugging it?

CheetahOP•16mo ago

how

Pobiega•16mo ago

well actually before that, I see a bug

        Console.ReadLine();
        string Guess = Console.ReadLine();

        Console.ReadLine();
        string Guess = Console.ReadLine();

you are doing readline twice that seems bad, so remove the first one

CheetahOP•16mo ago

i did now ok that fixed it? for some reason

Pobiega•16mo ago

well yes so what was happening is that you were entering a value that was ignored, then it was waiting for a second value and you didnt know

CheetahOP•16mo ago

oh ok

Pobiega•16mo ago

ReadLine() halts your application waiting for a string to be given, and only "resumes" after it sees an enter press since this was happening twice, your program was actually frozen

CheetahOP•16mo ago

ok thank you

Pobiega•16mo ago

however, you really should learn how to $debug

Pobiega•16mo ago

assuming you are using visual studio, this guide should teach you the basics

CheetahOP•16mo ago

ok ill read that some time

Pobiega•16mo ago

good its a way to see whats going on and what values your variables have etc while the program is running. you can also follow the execution line by line its extremely handy

CheetahOP•16mo ago

oh ok so with debug idont need to print it in my program it does it for me

SinFluxx•16mo ago

yeah, instead of Console.WriteLine(num); you can just debug to look and see what the value of num is
