First you have to switch to C++,
haven't you?

Not necessarily. It is possible to do OO in C as well. Some of the
early C++ compilers were actully just producing C code for the
underlying C compiler.

This, however, still does not make the OP topical here. The
comp.programmin g group might be a better place to start.

the question was not very clear, i rewrite:
how implément design pattern in style of object oriented programming in c ?
I think it could be simulate Object oriented by subtitute heritance
style by agregation style.

what you think about that ?

Yes, OO in C can be done that way. The simplest way to represent an
object in C is to add appropriate function pointers to a struct.

Really you are using the wrong language.

You can design some really elaborate schemes using C, like a function called
"void *queryinterface (Object *obj, char *name)", which returns a structure
full of function pointers implementing the given interface, given that the
object supports it. So a car might implement the "container" , "moveable" and
"light source" interfaces.

However it soon gets very unwieldy. You really want a language that will
hide the internal operations for you behind some intutive syntax.

For most users, this new feature is actually very convenient. If you want to control the update process,...
