ooc programmning language is a different project!
Object Oriented C (ooc)
kit is for those who want to program in an object orieneted manner, but
stick on the good old C as well. ooc implements classes, single
and multiple inheritance, exception handling. Ideal for students
getting to know OO programming in pure C.
It can be mainly useful for education and for small systems
that lack C++ compiler. Althoug I have written quite complex programs
using ooc!
By the help of ooc
you can write object oriented code in C with little efforts, though you
must understand the underlying object model.
Creating ooc my main
goal was to develop a lightweight object model, that provides many
features of C++ but is pure ANSI-C. Thus this is highly portable even
for small embedded systems as well. On other hand it was kind a "proof
of concept" and a hobby.
ooc is mature enough to be ported onto small microcontrollers, PICs, or DSPs.
ooc is like giving a good old steam locomotion a new life! :-)
Features
- Uses only C macros and functions, no language extensions required! (ANSI-C)
- Easy to read source code for your application. Care was taken to make things as simple as possible.
- Single inheritance of classes
- Multiple inheritance by interfaces and mixins (since
version 1.3)
- Implementing exceptions (in pure C!)
- Virtual functions for classes
- External tool for easy class implementation
Comparison
There are some other object models in C as weel. They may be worth a try. The mostly known is GObject, that is a very sophisticated system, but requires lot of typing, and subclassing is labor-intensive.
A short comparison table may help understand the key differences:

THIS ooc is a set of C macro collection and a small C library!
Unfortunately shares the name with some other projects of similar purpose.Shall you be interested in those, you can find them here:
