Question

consider the following C++ base and derived class declarations.

 

class BaseClass

{

   public:

      void BaseAlpha();

   private

      void BaseBeta(); //private data

      float baseField; //Private data

};

 

class DerivedClass : public BaseClass

{

   public:

      void DerivedAlpha();

      void DerivedBeta();

   private:

      int derivedField; //private

};

 

List all the private data members of BaseClass.

 List all the private data members of DerivedClass.

int derivedField;

List the private data members that the member functions of BaseClass can reference directly.

List the private data members tat the member functions of DerivedClass can reference directly.

List all the member functions that a client of the BaseClass can invoke.

 

 

Expert Solution
Step 1

To solve the above question, you should understand the basic concepts of object-oriented programming and the C++ programming language. In particular, you should have knowledge of class definitions, inheritance, access specifiers (public, private, protected), member functions, and data members.

In this example, we have a base class called BaseClass, which defines a public member function called BaseAlpha(), a private member function called BaseBeta(), and a private data member called baseField. We also have a derived class called DerivedClass, which inherits from BaseClass and defines two public member functions called DerivedAlpha() and DerivedBeta(), and a private data member called derivedField.
