Protected members can be accessed by the base class and any of its descendants (child class or child of a child class). answer choices True False
Person and Customer Classes Write a class named (Person) with data attributes for a person’s name, address, and telephone number. Provide accessors/getters and mutators/setters for each attribute. Write a displayPerson() to print out the attributes of the Person. Next, write a class named (Customer) that is a subclass of the (Person) class. The (Customer) class should have a data attribute for a customer number, and a Boolean data attribute indicating whether the customer wishes to be on a mailing list. Provide accessors/getters and mutators/setters for each attribute. Write a display customer() to print out the attributes of the Customer. Demonstrate an instance of the (Customer) class in a simple program.
Declare classes Person and Student where Student is derived from Person class. Person has Name and Student has RollNo as its private member. Create a Student class object and initialize it with the already existing object of Student class. Analyze the behavior of default constructors of Person and Student classes. Create a Student class object and initialize it with the already existing object of Student class. Analyze the behavior of default copy constructors of Person and Student classes. Explicitly write copy constructor for Person class. Analyze the behavior. Now, Explicitly write copy constructor for the Student class.
Create a class Animal and Add a protected data member named id of integer type. Add get/set methods for id data member in Animal class with public access. Also provide default constructor this should initialize id to 0. Also provide parameterized constructor and toString method. Add an abstract method tellAboutSelf method to Animal class with public access Add another abstract method speak method to Animal class. Reptile, Bird, Mammal Next create the three child classes which extends form Animal class. Add a default constructor to each of the above created class. The constructor should initialize the id data member id, Reptile, Bird and Mammal, to 1, 2 and 3 respectively also it display a message “(class Name)’s default constructor”. E.g. for Bird it says “Bird’s default constructor”. Add a parameterized constructor to each of the above created class. The constructor should initialize the id data member, Reptile, Bird and Mammal, to the specified id passed to the constructor also it…
Only___________ data members of a class can be accessed by a derived class. a. Private and public b. Public and protected c. Private and protected d. Private, protected and public
Complete the thick.h, thick.cpp, thin.h, and thin.cpp classes in the attached pizza solution. Modify your main.cpp class so that it creates a thin and thick crust pizza if selected by the user. Your solution should allow the user to order a regular, stuffed, thin or thick crust pizza. All child classes (stuffed, thin, thick) should inherit attributes and functions from the Pizza class. The stuffed class has already been implemented. The thick and thin class set_cost() funtions should differ in the following ways: thick crust has an additional charge of $2 thin crust has a cost discount of $1
A class that is not intended to be instantiated, but used only as a base class, is called a(n) __________. a. dummy class b. subclass c. virtual class d. abstract class
1- Create a class SchoolKid that is the base class for children ar aschool . It should have attributes of the child’s name and age ,the name of the child’s teacher ,and the greeting. It should haveappropriate accessor and mutator methods for each of the attributes. Derive a class ExaggeratingKid from schoolkid , as described above . The new class should override the accessor method for the age , reporting the actual plus 2. It also should override the accessor for the greeting ,returning the child’s greeting concatenated with the words “I am the best”.
When deriving a class with public inheritance, public members of the base class become _________members of the derived class, and protected members of the base classbecome______________ members of the derived class.
Every employee in a firm XYZ has attributes employeeid, name and salary. However the sales employees in firm XYZ has all the attributes of employees and also has an additional attribute named bonus. You are a software developer who has to the implement the relation between employee and sales employee. Write the code for classes employee and employee_sales. Write the constructors for both classes that set the attributes of both classes.
When the inheritance is private, the private methods in base class are __________ in the derived class (in C++).a. Inaccessibleb.. Accessiblec.. Protectedd. Public
A new class safe member that would allow us to export a reference to a member Suggest a simple scheme for creating a new class SafeMember that would allow us to export a reference to a Member. The classes outside the system should be unaware of this additional class, and access the reference like a reference to a Member object. However, the reference would not allow the integrity of the data to be compromised. Remember that when designing the “Return Book with fines” use case, Member object is returned to the UserInterface to be able to display the member information such as owed fine. But this also means that the UserInterface can access all the Member methods. Your implementation of SafeMember class should prevent this.
