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 ? B) Suppose you have a class called more which has a private object of a class called simple. ( both classes have public, protected and private members...

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.

URGENT!
Consider the following code for the definition of a Home object: 1 This class also contains getters, setters and a _str_method for it's owner and address attributes. class Home: def __init__(self, owner, address) self_owner owner, sell_address address Create a (derived) Apartment class that inherits from the Home class, but also has an attribute called rental price. Implement the Apartment class to inherit from the base Home class and contains all appropriate methods that need to be written for this...

In Exercise 1, displayAnimal uses an Animal reference variable as its parameter. Change your code to make the displayAnimal function anim parameter as an object variable, not a reference variable. Run the code and examine the output. What has changed? Polymorphic behavior is not possible when an object is passed by value. Even though printClassName is declared virtual, static binding still takes place because anim is not a reference variable or a pointer. Alternatively we could have used an Animal...
