Curiosity, (Coding c, C++)

craigengbrecht · Post by **craigengbrecht** » 04 Feb 2009, 03:12

As I am very new to coding, is it possible to run C code (the main part of the game) and C++ code running the sound engine? are they compatible working together or is this impossible?

Yes, this is possible, with a little fancy coding. Nothing too serious, but a deeper understanding of how C and C++ works will help you in your efforts. (In other words, programmers new to either language probably wouldn't be able to do it).

Got ya, But if I were able to learn and make it work, at least it is something I can strive for and work with.
I may be learning but a challenge is always welcome.

And here I thought C++ was back-compatible with C. Wouldn't it be enough just to say "This is C++ now!" on the C code and have it work?

C is a subset of C++, so in theory it is possible to compile C code as C++ code and everything works. However, the two have been drifting apart over the last few years, so if you flip that compiler switch you may get a (large) number of small errors that need to be resolved.

Yes, but we aren't using the drifted-apart versions - I think the '//' is one of the few C99 features we use, and that's definitely C++ compatible.

You will have issues compiling C code as C++ code, especially the Warzone source.

you may find what follows of some use in your studies.

started with c and found kernighan and ritchie's "the ansi c programming language" 2nd edition enjoyable (to my surprise) as much as edifying.

moved on to c++ (& script code based on) where i am currently entrenched. the work i found both delightful and extremely useful was (is)
"thinking in C++" (2nd Edition) in 2 volumes by Bruce Eckel (you can get as a no charge .pdf download & save your self a hundred bucks).

lastly, a work whose usefulness transcends particular languages (while using examples in c, c++, c#,vb, java and so on) that you should, i strongly feel, fully absorb, is called: "code complete: a practical handbook of software construction" by Steve McConnell. the lessons in this work are essential to a pro mastery, imho. an indispensable classic.

all good things, bud

Wow, the things you can learn in one week!
Thanks for all the tips guys, they will help speed my learning!

It is more than possible to write the sound engine in C++, so long as you provide a C interface for it. So as long as all of the functionality can be accessed from C (using extern "C" { ... } in the header file to ensure that C-style linking is used) then there is no problem.

Since we do not have a C++ coding style document, and any collaborative C++ project is hopelessly lost without it, I think it would be wise to stick to C for now. Otherwise you might get bogged down with questions far removed from those you were supposed to solve.

That sure is a understatement.
