That is ugly C++ code. It should be relatively easy to translate it to ugly C code: Put the class cvariables in a struct and then replace the public methods with functions accepting a pointer to such a struct.
Use array of characters instead of std::string instance and C I/O function instead of C++ streams. What else?

There is an alternative, of course: understand the logic an write a better C implementation.

Basically, don't.
You have found C++ code which does pretty much what your homework wants, and you think that just a simple translation will get you something to hand in.
It won't: C++ is (as the name suggests) a super-set of C, and that code uses features which aren't in C at all. Trying to convert that code to C will end up with really, really bad code! It's a bit like buying a Ferrari and cutting the body work off, welding on a series of huge boxes, changing the wheels and using it as a goods train.

Sit down, think about the question, and write your own code to submit. You might even learn something about how to produce code...
