    Simulating Inheritance in C

    To simulate inheritance in C what would be the better solution?

    1. Use the base Structure as a member of the derived one?

    2. Copy and paste the declarations for the base structure into the derived structure?

    3. Other option I haven't thought of?

    Any links in general to OOP with C?

    Here's one:

    7. It is easier to write an incorrect program than understand a correct one.
    40. There are two ways to write error-free programs; only the third one works.*

    I generally use option 1. Something like:
    Code:
    struct foo
    {
      int somedata;
      int somemoredata;
    };
    
    struct bar
    {
      struct foo basedata;
      int additionaldata;
    };
    If you understand what you're doing, you're not learning anything.

    You could just choose not to do this with C, but you're on the right track. Do a bit of Google searching to find answers to specific questions, but I found a decent article that will get you started.

    Thanks for the tips and the links. I am not thinking of doing anything too complex though. For that learning C++ would be a better option for me. I would prefer avoiding c++ because i prefer simpler languages. With c++ there are too many rules and exceptions to learn. With C I think I will be better able to understand what the code does. What I want is not necesarily to implement C++'s object model in C but maybe to think in an Object oriented way while coding in C. I think structures for encapsulation and void pointers for polymorphism would work well enough. I don't want the code to get too complicated because that would make c++ a better option.
