    Yes. If you want details, search the Web.

    Polymorphism in C NOT in C++...!!!

    I tried google but what all i found was C++ codes. Would you please take the trouble of explaining me things or post some good links?

    Polymorphism in C - CodeProject®
    Inheritance and Polymorphism in C - CodeProject®

    Both articles start by showing C++ polymorphism, but then move onto a C implementation.

    Note that:
    • I can read what you write.
    • I know which forum I am in when I post.
    • I do not confuse C and C++.
    • I have done exercises that simulate OOP in programming languages that either do not support certain OO techniques natively, or which was merely an exercise in simulating OOP.
    • I have partially read a fairly comprehensive article on simulating OOP in C.

    Before telling you to search the Web for details, I entered polymorphism in C into Google just in case C++ articles would have dominated the search. The first three results I got were concerned with C. The fourth was concerned with C#, the fifth was the Wikipedia article on polymorphism in computer science, and the next two were again about polymorphism in C. The first C++ specific entry was the tenth. So, if all that you found was on C++, I wonder at what search terms you used, or maybe your search engine just sucks

    The answer is in the question. C is not an OOP language, but can simulate the concepts. Same way you can use imperative statements in some data-driven languages, but that doesn't make them imperative programming languages.

    Simulation - Definition and More from the Free Merriam-Webster Dictionary
    Definition of SIMULATION
    3a : the imitative representation of the functioning of one system or process by means of the functioning of another <a computer simulation of an industrial process>
    Note: I have used C to simulate Assembly; but, I would never call C Assembly.
    Note: I have also use Macros to make C like Pascal; but that does not make C a Pascal language.
