Inheritance in Detail
This chapter formalizes and details some of the concepts introduced earlier in Chapter 6. We explain how constructors, destructors, and copy assignment operators are generated and used by derived classes. We discuss how the keywords public, private, and protected can be used for base classes as well as class members. We also provide examples of multiple inheritance.

23.4 | public, protected, and private Derivation | 536 |
