I think i understand "function pointer": a pointer that points to a function.

Function pointer-questions:
1) Can function pointer point to a static function?
2) Can function pointer point to a member function?
3) Can function pointer point to a virtual member function?
4) Why use function pointer? can i just use if/then to avoid the use of function pointer completely? (because i really am afraid of using function pointer)

generic-questions:
1) how to use ' extern "C" ' ? is it necessary ?
2) Why do we need multiple inheritance?

I do not see why not, so I say yes.

There are pointers to member functions, but they are not really function pointers.

Take for example qsort(). You certainly cannot just use if statements to replace passing the comparator function as a function pointer. The std::sort() generic algorithm takes a comparator that behaves like a function: so it could be a function pointer or a function object. In that sense, you can avoid function pointers in such cases by using function objects (possibly with template code).

We do not need multiple inheritance. That said, read Inheritance - multiple and virtual inheritance

You have to use function pointers to call some function in exe from dll - you cannot link directly, because dll does not knows about your exe...

Look at any win32 API that uses CallBack functions.

You can link, I do it all the time. For plugin systems for example it could be useful. For code modularizing/reusing it isn't
