hi im dchar3! you may remember me from such forums as the one from yesterday about hangman. i finished my hangman game and today i decided to try something someone told me yesterday. instead of declaring each string one at a time, i used an array. when it was done it worked perfectly fine, so i deleted the old source code and took a break. when i came back to the computer a few hours later, for absolutly no reason at all it says windows has encountered an error and needs to close. i tried to find the old source code that i deleted but it wasnt there. what the crap?

... because you deleted it?

You might have to be more specific. Do you mean you saved the source file, made the change, then compiled, then crashed before it was saved? I think most compilers save when you compile.

Without looking at the code, I could think to only a possibility: when you changed the code, and restarted the programm, an old memory state was used. I try to explain a bit better:
-You ran the first version. Everything went OK, and you exited from your program. But the memory was not cleaned-up.
-You changed the code, and restarted the application. This time the code isn''t correct, but, in some way, it doesn''t change the memory, and the program uses the values stored by the first version because OS assigns the same memory address to the variables.
-You put off the pc: memory is deleted.
-When the program runs again, it fails, because it try to access to memory of other processes.

I repeat: this is just an idea. Try to debug your app in order to figure out where is the problem, and while you''re executing it step by step, take a look into the memory it is changing.

Hope this helps. Good luck!

that makes sense, it is the first time i used arrays so i might have done it wrong. but every other time i compile something with bad code, it doesnt even compile so i know theres nothing wrong with the source code.

heres the code, it should be right
