This book provides instruction for using C in an object-oriented fashion. The book covers the problems likely to arise in a C++ application, explains why C++ is inappropriate for some object-oriented applications, and shows how to do real object-oriented programming (based on a multitasking model) in a C or C++ environment. Using real-world examples throughout, the book relates C++ concepts directly to C, showing how a C++ feature could be implemented in C by presenting code in both languages. Readers will see exactly how the object-oriented methodology works and how it can be implemented in both C and C++.
