If you're asking others to do your homework for you than I think it is time to for you get out of the course or program you're taking.

[masket]

The teacher is not my best friend and won?t help me so i?m askeing anyone to help me not doing the whole programm for me

[nvme]

any chance you could put the strings in english?

edit: actually.. all of it

You are about to learn the value of commenting your code:):)

If your source was in a zip file it would be easier for others to try and debug. I know I don't want to copy-paste-splice-into-correct-files.

[masket]

If i can?t do something my teacher tells me to find it on the internet lol,my teacher is an ass****

Yes i know i do alla the commenting after i?m done with my program:):)

debuging is not my speciality

give me you?re email and i?ll send it to you ziped

Thank you

He probably thinks he's teaching you how to learn independently. Good, when a solid foundation has been laid. If not, it'll all just sink into the mud.

no link and you need to tell people the problem

[Rudy]

ut would take ALOT more than 5$ for me to try to go through this mess you call code....

[masket]

Don?t know what is wrong

[dsfirth]

Where's the Makefile? How do you compile your source code?

[dsfirth]

  masket said:

Well, for starters you don't have type declarations for your class members. gcc screamed at me for more lines than are in your code. This looks like a do-over.
