C++ : Defining class Person, class Student, class Teacher and class Graduate. Note that class Student and class Teacher inherits from Person, and class Graduate inherits from Student. Defining two constructors (including a default constructor) for each class. Defining virtual function print() for three classes (person, teacher and graduate), where each has different function body. Writing a main function to test the above definition and run each print function.
(Program) a. Complete the following class by including functions corresponding to the two prototypes listed in the declaration section: classElevatorprivate:intelNum;//elevatornumberintcurrentFloor;//currentfloorinthighestFloor;//highestfloorpublic:Elevator( int=1,int=1,int=15);//constructorvoidrequest( int);; In this definition, the data member elNum is used to store the elevator’s number, the data member currentFloor is used to store the elevator’s current floor position, and the data member highestFloor is used to store the highest floor the elevator can reach.The constructor should allow initialization of an object’s three data members with the data passed to the constructor when an Elevator object is instantiated. The request function should code the following algorithm: If a request is made for a nonexistent floor, a floor higher than the topmost floor, or the current floor Do nothing ElseIf the request is for a floor above the current floor Display the current floor number While not at the designated floor Increment the floor number Display the new floor number EndWhile Display the ending floor number Else // the request must be for a floor below the current floor Display the current floor number While not at the designated floor Decrement the floor number Display the new floor number EndWhile Display the ending floor number EndIf b. Include the class written for Exercise 3a in a complete program, and verify that all member functions work correctly.
Assume the definition of class houseType as given in Exercise 11. Answer the following questions. (1, 2, 3, 5, 7) a. Write the definition of the member function set so that private members are set according to the parameters. b. Write the definition of the member function print that prints the values of the data members. c. Write the definition of the constructor of the class houseType so that the private member variables are initialized to according to the parameters. d. Write a C++ statement that prints the value of the object newHouse. e. Write a C + + statement that declares an object house of type newHouse, and initializes the member variables of house to "Ranch", 3, 2, 2, 2005, 1300, 185000, and 3600.0, respectively. f. Which function members are accessors and which are mutators?
C++ a) Implement a class Animal.data members:type – an automatic variable (mammal, fish etc.)functions:accessor - an accessor for the type variableoutput() - output the type of animal b) Implement a class Human which is derived from Animal. data members:name - a dynamic variable (name of human)functions:accessor - an accessor for the name variableoutput() - redefined to output name and type
Define the class RectangularCube in C++. A RectangularCube has three sides length(L), width (W), and Height (h), define the sides as private data fields. Include a no-argument constructor that sets all three sides to 1. The class must also have a constructor that receive parameters to initialize sides of the RectangularCube. Include get and set functions for all three data fields. Finally define the functions volume () and surfaceArea () in the class RectangularCube that use the formulas given below to calculate and return the volume and the surface area of the RectangularCube. Give the UML diagram of the class, you may use the MSOffice/Visio to create the UML class diagram (best to download and use Visual paradigm tool, or any other free UML tool). Implement the class using separate files for definition and implementation, use inclusion guard to avoid duplicate code. Make sure to include at least one inline function implementation. Do not Implement the volume () and the SurfaceArea…
Using c++ Book information (overriding member functions) Given main() and a base Book class, define a derived class called Encyclopedia. Within the derived Encyclopedia class, define a PrintInfo() function that overrides the Book class' PrintInfo() function by printing not only the title, author, publisher, and publication date, but also the edition and number of volumes. Ex. If the input is: The Hobbit J. R. R. Tolkien George Allen & Unwin 21 September 1937 The Illustrated Encyclopedia of the Universe James W.

Q. Please solve this C++ program and show all the steps. (kindly do not use any advanced coding or coding info from any other program. Don't copy from other sources too) a) Add a new function convMonth to the class Date that returns the month in letters (e.g., January, February, etc.). b)Add a function that prints the date using the following format: Month dd, yyyy . Example, January 21, 2023 c) Test the new functions of the class Date by creating dynamically (i.e., using pointers) two objects of the class Date and invoking the new member functions on both objects. Deliverables: date.h, date.cpp, testdate.cpp. (any description or thought process of this coding problem will be really useful, particularly in part c) please let me know if there's any way I could contact you for further assistance,( please!) Thank you !

Write the following program in C++. 1. Create a class called Employee that includes attributes: empid, name, points,group, and avg with data types: “int”, “String”, “double”, “String”, and “double”respectively.2. Include a constructor with parameters: empid and name.3. Include another constructor to assign default values to the attributes.4. Include a function called addPoints that is used to add a given amount to the valueof the attribute points.5. Include a function called upgradePoints that is used to increase the value of theattribute points by a given percentage.6. Include a function called removePoints that is used to reduce a given amount fromthe value of the attribute points. If the resultant value is negative then the value ofthe attribute should be set into zero.7. Include a function called computeGroup that assigns a value to the attribute groupbased on the value of the attribute points as given in the following table. Points Group points < 100 Silver 100 ≤…
In C++, write a simple software that computes the total points based on the Practical Examination Rubric Detail using functions inside a class. Create objects with three input arguments in the main function (SO1.3, SO6.1, and SO6.4, respectively) which values range from 1 to 4 (1 = Beginning, 2 = Developing, 3 = Accomplished, 4 = Exemplary). The sum of the related points will be displayed in the output.
