Methods in C

Written by Paul Buetow 2016-11-20

You can do some sort of object oriented programming in the C Programming Language. However, that is very limited. But also very easy and straight forward to use.

Example

Lets have a look at the following sample program. Basically all you have to do is to add a function pointer such as "calculate" to the definition of struct "something_s". Later, during the struct initialization, assign a function address to that function pointer:

Taking it further

If you want to take it further type "Object-Oriented Programming with ANSI-C" into your favorite internet search engine, you will find some crazy stuff. Some go as far as writing a C preprocessor in AWK, which takes some object oriented pseudo-C and transforms it to plain C so that the C compiler can compile it to machine code. This is actually similar to how the C++ language had its origins.
