Sams Teach Yourself C in 21 Days

Q Can I use member functions in structures in my C programs?

ANo. Remember that C++ structures are a specialized type of class. Member func-

tions are a part of a class. C does not have a class construct, so you shouldn’t try to

use classes, nor should you try to use member functions.

Q Can I write full-fledged C++ programs using what is covered in this book?

AYou can write complete C++ programs using what was learned in the lessons in

this book; however, you have only learned a few of the basics of C++. If you try to

update or modify existing C++ programs, you may find that they are much more

complex than any you saw here.

Q Can you inherit from more than one base class?

AYes. In C++ you can inherit from multiple base classes. Just as you inherited from

both your mother and your father, a class can have multiple parents. The new sub-

class, then, has characteristics of both of the base classes. It is beyond the scope of

this book to go into more detail on this.
