How to implement several source files?

This is a good idea - whay you would end up with is several source files containing the code, and perhaps a single .h file describing the interfaces

Now I want to implement the calculations in my program, but separated as I said.

I like Salem's idea, but I don't know how to "make it" (I can't think of an Enlish expression, sorry).

Any help?

What you would basically do is connect the source files (.c) to each other via a header file (.h). You would, summed up, aquire this by using the #include (don't forget with double quotes, not < and >).

Thanks Garfield.

Now I'm being told more or less how to do it (not more or less, totally ;) )

Obviously that was me, I forgot to login.

Thanks again
