In this version, the properties 

Width

 and 

Height

 provide access to the private members, 

pri_width

 and 

pri_height

, which actually store the values. Therefore, even though 

pri_width

 and 

pri_height

 are private to 

TwoDShape

, their values can still be set and 

obtained through their corresponding public properties.

When referring to base and derived classes, sometimes the terms 

superclass

 and 

subclass

are used. These terms come from Java programming. What Java calls a superclass, C# calls 

a base class. What Java calls a subclass, C# calls a derived class. You will commonly hear 

both sets of terms applied to a class of either language, but this book will continue to use 

the standard C# terms. C++ also uses the base-class/derived-class terminology.
