Help With The Code Playground Compiler

Question

This code I made for a console game,worked PERFECTLY fin on my pc with gcc BUT it gives alot of errors when I run it here at the code playground,and one of the errors is for unknown type 'bool'..... Idk how this compiler works but wanted to still upload my work.Any help would be appreciated

Edit:
I managed the bool error by using "_Bool"(which seemed completely pointless) but still the other errors are there....

Edit 2:
I worked out all the errors but wtf it dosen't even wait for input,how am I supposed to input all needed vals without any helping text...Can anyone tell me why this compiler is sooooooooooo crappy?

Answer 1

please add the code here instead of the error messages, this is really disturbing

Answer 2

*AsterisK* The code is really long over 200 lines,but its the only code I've posted on my profile, you can find it easily, its under 'EveOdd'

Answer 3

Bennett Post That's strange then,gcc compiles my code with 'bool' pretty nicely and I did fix that error by using '_Bool'

Answer 4

it seem to be working fine now

Answer 5

*AsterisK* It dosent on mine.Its supposed to dynamocally take values,taking input for player's score/num AFTER displaying and calculating the opponent's.But you have to enter it all together in playground.........it dosen't take input,only once when you run it........
