5. Multiple Choice Questions: • A non-default destructor is needed 1. always (for correct operation) 2. optionally 3. only if a developer wants to be more explicit than the default when there will be more than one instance of a class 5. when class data members are dynamically allocated 4. Consider the following code: int x = 15; // located in memory at 0x1236 int* intPtr; // located in memory at Ox1240 intPtr = &x; cout << *intPtr; What is its output? 1. an error 2. 15 3. a random number 4. 0x1236 5. 0x1240 • The following function prototype is for the UberObject & operator-(UberObject & rhs); 1. copy assignment 2. default constructor 3. move constructor 4. move assignment 5. copy constructor

Programming Assignment #5 Educational Objectives: After completing this assignment the student should have the following knowledge, ability, and skills: Define a class hierarchy using inheritance Define virtual member functions in a class hierarchy Implement a class hierarchy using inheritance Implement virtual member functions in a class hierarchy Use initialization lists to call parent class constructors for derived class constructors Operational Objectives: Create (define and implement) a base class Shape classes that will inherit this class called Box, Rectangle, Circle, and Triangle Description: Programming Specifications: You will have a base class of Shape which will have an area and perimeter of type double. You must also create acceptable Gets and Sets for the private data items. All of the other classes will inherit this class. You will have a class Square which will have just one length of type double. You should create acceptable Gets and Sets for the one…

define a class person which has two data members. they are 1.pointer to character to store address of memory block to store name of person . 2. CNIC data member to store ID card number class person has also a constructor and distructor use class person as parent class and define child class student child class student has two data members. They are pointer to character and Roll no. NOTE that chaild class also has a constructor and distructor. In addition child class has two data member more member function to get data and display data. In main function , creat an object of class student and display information of student.

C++ Programming. Theme : Encapsulation and inheritance Task : General setting. The program must contain: • base class X, which includes two elements x1, x2 of type int, • constructor with parameters for creating objects in dynamic memory area, • destructor, • virtual methods for viewing the current state and reinstalling base class objects to a new state. • derived class Y, including one element y of type int , • a constructor with parameters and an initializer list, passing data to the base class constructor, • overridden methods for viewing the current state of objects and reinstalling them to a new state. Create a Run method in the derived class that defines: Value х1×х2-у
