C++20 for Programmers: An Objects-Natural Approach, 3rd Edition

9. Custom Classes

Objectives

In this chapter, you’ll:

• Define a custom class and use it to create objects.

• Implement a class’s behaviors as member functions and attributes as data members.

• Access and manipulate private data members through public get and set functions to enforce data encapsulation.

• Use a constructor to initialize an object’s data.

• Separate a class’s interface from its implementation for reuse.

• Access class members via the dot (.) and arrow (->) operators.

• Use destructors to perform “termination housekeeping” on objects that go out of scope.

• Assign the data members of one object to those of another.

• Create objects composed of other objects.

• Use friend functions and declare friend classes.

• Access non-static class members via ...
