Design the class patientType, inherited from the class personType, with additional data members to store a patient’s ID, age, date of birth, attending physician’s name, the date when the patient was admitted in the hospital, and the date when the patient…
In this exercise, you will design a class memberType.a. Each object of memberType can hold the name of a person, member ID, number of books bought, and amount spent.b. Include the member functions to perform the various operations on the objects of memberType—for example, modify, set, and show a person’s name. Similarly, update, modify, and show the number of books bought and the amount spent.c. Add the appropriate constructors.d. Write the definitions of the member functions of memberType.e. Write a program to test various operations of your class memberType
In Chapter 10, the class clockType was designed to implement the time of day in a program. Certain applications, in addition to hours, minutes, and seconds, might require you to store the time zone. Derive the class extClockType from the class clockType by adding a member variable to store the time zone called timeZone. Add the necessary member functions and constructors to make the class functional. Also, write the definitions of the member functions and the constructors. Finally, write a test program to test your class. Codes Given: clockType.h & clockTypelmp.cpp clockType.h //clockType.h, the specification file for the class clockType #ifndef H_ClockType #define H_ClockType class clockType { public: void setTime(int hours, int minutes, int seconds); //Function to set the time. //The time is set according to the parameters. //Postcondition: hr = hours; min = minutes; // sec = seconds // The function checks whether…

Create a class Student that contains information about a student’s name, semester, roll no, and date of admission. To store the date of admission, use a structure to define date. Providea. a no-argument constructor for initializing the values of data members to some defaults. b. a 4-argument constructor to initialize the data members sent from the calling function at the time of creation of an object (date should be sent from outside in the form of a date object). c. An input function for setting the status of a student. d. A display function to display all the attributes of a student. Derive a class undergraduate from Student class that contains some additional information. This information is about the semester GPA of a student and the credit points earned per semester. To store this data, provide a 2D array (2x8 array since at maximum there are 8 semesters for an undergraduate program). One dimension of the array should hold information about the SGPA of each semester so far and the…
Use C++ Create a class called Fruit. Add one member variables name. Add only one getter function for the name. The get function returns name. Implement a constructor that expects name value and assigns it to the member variable. This class doesn't have an empty constructor. Create a subclass of Fruit named CitrusFruit. The CitrusFruit class has two member variables weight and color. Add a constructor which expects weight and name and color.Pass name to the base constructor and set weight and color to it's member variable. Write a program that has an array of 3 Fruits, and an array of 3 CitrusFruits. Feel free to give the name , weight and color to the object as your choice. Use loops to print out the array properties to the terminal screen.
Program: Circle.h and newCircle.cpp 1: Create a class specification file, Circle.h, that contains the Circle class declaration 2: Create a class implementation file, Circle.cpp, that contains the member function definition, with a constructor that can accept arguments 3. Based on Program 13-8 in the textbook, create a program, newCircle.cpp, that generate two instances of the Circle class, pizza1 and pizza2, which can have different size (radius). Hint: Use the example source code in “Rectangle Version 4.zip” to create a multi-file project. Step 1: In Dev-C++, go to file à New à Project to create an empty project Setp 2: Go to ProjectàAdd to project, add new cpp files (e.g. Rectangle.cpp and Pr13-8.cpp files). Step 3: Compile and run Problem 2: Read the example source code in “HW2Problem2.zip” and modify it as follows: 1. Modify the code and create three rectangle objects, box1, box2, and box3. 2. Modify the code and create some static member function(s) that can count…
7. PersonData and CustomerData classesDesign a class named PersonData with the following member variables:lastNamefirstNameaddresscitystatezipphoneWrite the appropriate accessor and mutator functions for these member variables. Next, design a class named CustomerData, which is derived from the PersonData class. The CustomerData class should have the following member variables:customerNumbermailingListThe customerNumber variable will be used to hold a unique integer for each customer. The mailingList variable should be a bool. It will be set to true if the customer wishes to be on a mailing list, or false if the customer does not wish to be on a mail- ing list. Write appropriate accessor and mutator functions for these member variables. Demonstrate an object of the CustomerData class in a simple program.
