Chapter 15: Problem 34

Write the first line of the declaration for a poodle class. The class should be derived from the Dog class with public base class access.

Short Answer

Expert verified
Answer: To create a Poodle class deriving from the Dog class with public access, use the following syntax for the class declaration: ```cpp class Poodle : public Dog { ```

Step by step solution

01

Write the class declaration for Poodle

To create a derived class, use the syntax 'class DerivedClass : access-specifier BaseClass'. In this case, the derived class is 'Poodle', the access specifier is 'public', and the base class is 'Dog'. The first line of the Poodle class declaration should look like this: ```cpp class Poodle : public Dog { ```

Most popular questions from this chapter

True or False The base class's access specification affects the way base class member functions may access base class member variables.

What is the difference between redefining a base class function and overriding a base class function?

Write the declaration for class B. The class’s members should be • m, an integer. This variable should not be accessible to code outside the class or to member functions in any class derived from class B. • n, an integer. This variable should not be accessible to code outside the class, but should be accessible to member functions in any class derived from class B. • setM, getM, setN, and getN. These are the set and get functions for the member variables m and n. These functions should be accessible to code outside the class. • calc, a public virtual member function that returns the value of m times n. Next write the declaration for class D, which is derived from class B. The class’s members should be • q, a float. This variable should not be accessible to code outside the class but should be accessible to member functions in any class derived from class D. • r, a float. This variable should not be accessible to code outside the class, but should be accessible to member functions in any class derived from class D. • setQ, getQ, setR, and getR. These are the set and get functions for the member variables q and r. These functions should be accessible to code outside the class. • calc, a public member function that overrides the base class calc function. This function should return the value of q times r.

True or False Private members of a protected base class become inaccessible to the derived class.
