Exam 11: Object-Oriented Programming: Inheritance

A base class's constructors are inherited into its derived classes.

Every object of a base class is an object of that class's derived classes.

A key to improving the software development process is encouraging soft ware reuse.

Multiple inheritance,widely used in C#,is the process of inheriting from more than one class.

When a program creates a derived-class object,the object constructor is the last constructor called and the first whose body finishes executing.

The first task of any derived-class constructor is to call its base-class con structor.

A "copy-and-paste" approach is a simple and efficient way from a software-engineering perspective of providing func tionality that exists in other classes.

A base class is often designed by factoring out commonalities among a set of classes.

Inheritance preserves the integrity of a base class.

A derived class is often larger and more general than its base class.

If a base class constructor is overridden,the original constructor can no longer be called explicitly by the derived class.
