Suppose the base class and the derived class each have a member function with the same signature. When you have a pointer to a base class object and call a function member through the pointer, discuss what determines which function is actually called—the base class member function or the derived-class function.

Create a base class and two derived classes. Also, create and call a member function named communicate() that behaves differently when called by each class. Create a single C++ project (and CPP source file) named animal_communication as follows: Into this source, type the source code for Program 15-16, "Program Output," in Section 15.6, "Polymorphism and Virtual Member Functions," in Ch. 15, "Inheritance, Polymorphism, and Virtual Functions," of Starting Out With C++ From Control Structures Through Objects.

C++ questions 1. _____ binding is when the compiler binds member function calls at compile time. 2. Matching a function call with the correct function is called _____. 3.____ is when member functions in a class hierarchy behave differently, depending upon which object performs the call. 4. When a pointer to a base class is made to point to a derived class, the pointer ignores any ____ the derived class performs, unless the function is _____.

A) Suppose you have a class called base which has been inherited by a class called derived. ( both classes have public, protected and private members ) What can a client of derived access within the class base ? What can the class derived access within the class base ?

Pure Abstract Base Class Project. Define a class called BasicShape which will be a pure abstract class. The class will have one protected data member that will be a double called area. It will provide a function called getArea which should return the value of the data member area. It will also provide a function called calcArea which must be a pure virtual function. Define a class called Circle. It should be a derived class of the BasicShape class. This...
