Why talk about the OO advantages and so on with respect to languages; OO is a methodology not a language. You can write NON-OO (random function) programs with C++ just as much as you can write OO programs including full inheritance (single and multiple) using C (with not overwhelmingly more effort). The main reason for using C++ over C for OO programs is that your OO structures are syntactically checked by the compiler whereas they are not for C and, of course, you have the battle hardened STL library to use. I've only used C recently once, for a DSP project, where the C++ compiler turned out to be useless.
