EC Lecture Notes - Lecture 6: Object Composition, In C
Document Summary
In the real world, complex objects are typically built using smaller, simpler objects. For example, a car is assembled using a metal frame, an engine, tires, and a large number of other parts. In c++, object composition involves using classes as member variables in other classes. It contains person and birthday classes, and each person will have a birthday object as its member. It also has a constructor that initializes the members using a member initialization list. The class was declared in a single file for the sake of simplicity.
