C or C++?
April 22, 2002 04:42 PM
I often hear that C++ adds an extra overhead with classes and that many games are programmed in plain C. I''m currently learning C++ but I was wondering, should I aslo be proficient in C (ie learn the procedural way)? Will all games be programmed in C++ eventually?
I hate signatures.

Some of the mechanisms available to you through classes (e.g. virtual functions) have an overhead cost. But implementing the same mechanisms in C would give you the same (or worse) overhead. Objects with expensive constructors will be expensive to instanciate. Same in C, if a data structure requires expensive initialisation.
Yet, C++ has features which are actually more efficient than the C equivalent (case in point: sorting with an inlined predicate, as opposed to using qsort() with a function pointer). Do learn to use the Standard Template Library. It contains better code than most of us can write.
The point is to know exactly what features are costly and where/when to use them or not. That''s at least as important as knowing the language itself.
Now, to actually answer your question, knowing C does no harm. After all, the C library is also part of the C++ library, and C++ can very well be used as a "better C", without ever using a single class.

It''s probably a good idea to start with C. As Fruny said, C is a subset of C++ (all that you can do in C you can do in C++) so learning it first won''t harm you in any way. In my opinion C is easier to learn for a beginner than diving right into C++ (then again it''s just my opinion). Also it''s good to know the straight up C because things like handhelds use it. GBA uses C for instance.

There are so many "Should I use C or C++?" threads out there...

It''s too late, I already like the concepts of OOP so I''m into C++. I admit those concepts add extra difficulty though. Anyway, I''m only at the "C with classes" point for now. I''m not aiming for handhelds but I guess I''ll know C when I get into the industry.

If by "out there" you mean outside of gamedev, I''ll say I''m not interested in developing normal software.

Personally, I believe that C++ is an excellent second language. Exposure to a fairly restrictive beginner''s instruction language like BASIC or Pascal is a good way to learn the fundamental concepts of programming, and after that migration to C++ and absorption of OO principles.
No, he means here on GameDev. You can use the search feature to find and check them out.

i agree too....
i had learn pascal , cobol and C before getting into C++..
COBOL trivia. Did u know that cobol was created by a grasshopper ????
{ Stating the obvious never helped any situation !! }

Grace Hopper == grasshopper? As a pun/joke, this must be one of the worst I have heard in a long while.

I learned some kind of BASIC on a Texas Instrument calculator. All integer variables were predefined and global, which led to pretty ugly and hard to maintain code, but I had no problem with control flow when I switched to C++. The OO approach is surprising at first because it tends to mimic the real life semantics.

Was that a Jay Leno question?
