Navigating C++ and Object-Oriented Design

4.14. Key Point Summary

• Objects have inside and outside views. Encapsulation allows designers to separate class interfaces from implementations.

• The private section of a class specifies members available only to member functions and friends of that class. The public section's members are available to member functions, friends, and user programs.

• Constructors build class objects and destructors release them. The compiler calls constructors when you declare objects, and calls destructors when objects go out of scope. The compiler also calls constructors when you use operator new to create free store objects, and calls destructors when you use operator delete with free store object pointers.

• Default constructors have either void argument lists or signatures ...
