Whenever I run the program, it's fine until I get to the point where it asks which game they want to play. if I select 1, it'll ask for my number, if I give a number bigger than 30, the program quits. I didn't program it to do that. If I pick a number 30 or below, it'll run it fine, but if the number the computer guesses is too low, it'll repeat that same number over and over and not change. Also, if I select option 2, the program will quit.

example of 1st issue:
Select number: 25
is this your number?: 55
too high: 45
too high: 30
too high: 15
too low: 15
too low: 15

Edited my code: It works, to an extent. I can't exit my loop with -1

Progressing slightly, but now I'm truly at a stalemate. I've spent ~ 35 - 40 min trying different solutions to my problem, and now I'm stuck.

I can't get myNum > 100 to actually work correctly, it'll pretend I entered a number and computer starts guessing.
I also can't get the computer to properly guess, say he guess 22 and it says too low, there's a chance he'll guess 22 again either later, or directly after guessing 22..

Please, any help.. at all.. Test the code out for yourself, and let me know what ya think, what a solution, anything. Not homework, just projects during class break.

Make it so you can't enter bellow 1 or above 100 so a glitch doesn't happen.
(This won't solve your problem, just make it more user friendly.)

Okay, I got it. It took awhile but it works. I tested it like 300 times. Here is the code: (the underlined stuff is what I added and edited.)

Try it. I hope it works.

One error whit what I just posted. If the user enters the number '0' for the computer to guess it glitches. Make it so it says you can't enter bellow 1.

I'll try it out tonight! Thanks for the reply!

My only issue is.. When I enter a number greater than 100, it'll still continue on with the game as if I entered something below 100.

Just use if to tell it not to go above or bellow those numbers.
