Chapter 15: Problem 11

What base class is named in the line below? class Pet : public Dog

Short Answer

Expert verified
Answer: Dog

Step by step solution

01

Identify the inheritance syntax in C++

To identify the base class, we need to know the syntax for inheritance in C++. In C++, the derived class inherits from the base class using the ":" symbol followed by the access specifier and the name of the base class.
02

Locate the base class in the given code snippet

In the given line of code, we can see the ":" symbol, which signifies inheritance. The code provided is: class Pet : public Dog
03

Identify and name the base class

In the code snippet, the class "Pet" is inheriting from the class "Dog" with the "public" access specifier. The base class in this case is "Dog". So, the base class named in the given line of code is Dog.

___________ binding is when a function call is bound at runtime.

A(n) ________ class cannot be instantiated.

How does base class access specification differ from class member access specification?

Write the declaration for class \(B\). The class's members should be \(\bullet\) \(\mathrm{m},\) an integer. This variable should not be accessible to code outside the class or to member functions in any class derived from class B. \(\bullet\) \(\mathrm{n},\) 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. \(\bullet\) 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. \(\bullet\) calc, a public virtual member function that returns the value of m times n. Next write the declaration for class \(\mathrm{D}\), which is derived from class \(\mathrm{B}\). The class's members should be \(\bullet\) \(\mathrm{q},\) 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 \(\mathrm{D}\) \(\bullet\) \(\mathrm{r},\) 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. \(\bullet\) 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. \(\bullet\) calc, a public member function that overrides the base class calc function. This function should return the value of q times \(r\)

An overridden base class function may be called by a function in a derived class by using the _______ operator.
