Question: Okay, you may call me a noob but I'm realling confused.

My ex classmate paid me to write a program in C. She gave me the task and it said something like "blah blah blah make at least TWO CLASSES, write at least ONE CONSTRUCTOR and rewrite at least ONE METHOD" it says that word by word.

And then I told her "this is C++ not C" she said "but we're learning C"

I ignored it and wrote the program in c++ and sent to her as I thought she didn't know what she was talking about. She said "it doesn't work on code blocks, and wtf is cout <<" and then she sent me a chunk of code that they write and instead of cout and cin there was printf and scanf. It had to be C. So, I rewrote the program with printf and scanf and she still says codeblocks throw errors (I still left classes as task demanded).

I want to ask wtf? Does C have classes? Or is there a misunderstanding or something?

EDIT: I've come back to the question after so many years and noticed some a\*\*\*\*\*es took time to remove 99% text from the question. Get a life, this is not 1984 yet.

Answer: 
No, C has no classes per se, only C++ (which started out as "C with classes" back then...). But you can use the standard C library in C++ code, even if it is often not considered good practice (where C++ has its own, higher level constructs, e.g. `cout` vs `printf`).

You can sort of emulate the behaviour of classes, inheritance and virtual functions in C too, but it's not worth the pain.

You should probably buy/get your ex classmate a C programming book :-)
C does not have classes.

But one can approximate a class by using static globals as private class members, and static functions as private member functions. extern members as public. In this case an entire file could be viewed as a class.

Probably this is not what you want.
