a c++ program in which class A is base class for class B. While Class C is derived from class B and class D is derived from class E. Provide explicit implementation of default constructors and destructors. Write a test program which initializes each class object and shows execution order of constructor and destructor by printing appropriate messages.
Modify the above classes and provide overloaded constructor implementation for each class. (Note: Use base initialize for this purpose)

- Write a program IN C++ to model a student class with roll number and name as the sensitive information. Initialize default values for the sensitive information using a default constructor, use a copy constructor to copy from another object, use a member function to take user input and update the name and roll number and display the same using another member function. b.Add constructor overloading to the above code and enable initialization of name, roll number via constructor arguments. NAME ROHI ROLLNO 18Write a program IN C++ to model a student class with roll number and name as the sensitive information.

NAME KOHLI ROLLNO 18This lab will exercise your understanding of some of the concepts covered in Chapter 13:overloading operators 1. Create a class, name of your choice, to represent a college class in which students might register. a. Create three private member variables:Class Name (to hold values such as CSC210)Number of StudentsClass Hours b. Overload the >> operator to input, from cin, into the class object, the Class Name and Class Hours c. Overload the << operator to output all the private member variables d. Overload the + (plus) operator to add a value to the Number of Students private member variable.This will represent students registering for the class. e. Overload the - (minus) operator to subtract a value from the Number of Studentsprivate member variable. This will represent students dropping the class. f. The default constructor should initialize the private member variables appropriately. 2. Write a client program to: a. Upon program execution, create one class object that…
- This chapter uses the class rectangleType to illustrate how to overload the operators +, *, ==, !=, >>, and <<. In this exercise, first redefine the class rectangleType by declaring the instance variables as protected and then overload additional operators as defined in parts 1 to 3. Overload the pre- and post-increment and decrement operators to increment and decrement, respectively, the length and width of a rectangle by one unit. (Note that after decrementing the length and width, they must be positive.) Overload the binary operator – to subtract the dimensions of one rectangle from the corresponding dimensions of another rectangle. If the resulting dimensions are not positive, output an appropriate message and do not perform the operation. The operators == and != are overloaded by considering the lengths and widths of rectangles. Redefine the functions to overload the relational operator by considering the areas of rectangles as follows: Two rectangles are the…Write a program to display the given details with the normal constructor and the copy constructor.Strictly adhere to the Object-Oriented specifications given in the problem statement.

- Write a program in C++ , which has three classes one, is StudentRecord having members (degree,year) and functions (getdata), the 2nd class is called EmployeeRecordwhich has data members (emp_id and salary). The 3rd class is Manager having title, dues and an object of EmployeeRecord as well asStudentRecord. Create a function of getdata in all of these classes and call where necessary. Using this scenario, show how the concept of Composition works.write a class implementation using C++ from the given class diagram TAKE NOTEOF THE FF SPECIFICATIONS: Using the constructor, create three objects from class Voters and store it in the stack memory. Two voters must have an active account and one voter has a deactivated account. Please note that the deactivated voter account must be still part of the “object”. Test all the functions by making calls. this should be the sample result. Please use simple codes only.Hi can you assist me on the problem below for a class and a test class that conforms to the following specifications: 1. The name of the class is RightTriangle 2. The class has member variables base and height 3. The class has a constructor that initializes base and height 4. The class has accessors and mutators for base and height 5. The class has a toString method that produces String representation of a RightTriangle like the following example for a triangle with base 12 and height 10. Base : 12 Height 10 6. The class has a method called findArea to compute the area of the right triangle. Here is a suggested implementation. public double findArea() { return 0.5* this.base*this.height; } 7. The class using proper naming conventions Write a test class called RightTriangleTest that conforms to the following: 1. Create an object with base = 10 and height = 20, for example myTriangle. 2.
