a. Write the specification (i.e., what would be in a header file) for a class called studentType. Code the data member section (as private) and the function prototypes (as public). You do not need to write any include, using or other directives. Include the following: Data: Student First Name Student Last Name Student gpa Student ID

I have the basis of a program that works as an inventory, it reads the contents of a file and displays them and their quantity in three places, listed below are the things that I need to add to the program below. Provided is the current code. 1) Convert your structure into a class. For this exercise, you can leave the data as public (otherwise you would have to change the input and output functions). 2) Write a member function show_all that prints all the information for one record - name, cost, markup, and the three inventory numbers. 3) Add a user option S that lets the user see all the information for all the items in the inventory, using the show_all member function. Print a header so the user knows what each column means, and format the output to appear in columns. Hint: do a setwidth() before *each* cout. Pick widths that make sense for name, cost, markup, and the three inventory numbers. Contents of the file: Contents of Inventory.txt Red delicious apples1.00 25 6 8…
Using C++ and Visual Studios Using your own creativity, make a set of class templates that have these features: For this class template, put everything in one place--do not declare the member functions and have separate definition of the member functions elsewhere. Keep them in one place. Include a private variable. Include a constructor that loads the private variable when constructed. Include a destructor that clears the private variable to zero. Include set and get functions to set and get the private variable.
Rewrite the calculator program using a class called calculator. Your program will keep asking the user if they want to perform more calculations or quit and will have a function displayMenu to display the different functions e.g .(1 - addition, 2- subtraction, 3- multiplication, 4- division) Your program must have appropriate constructors and member functions to initialize, access, and manipulate the data members as well as : A member function to perform the addition and return the result A member function to perform the subtraction and return the result A member function to perform the multiplication and return the result A member function to perform the division and return the result
In C++ 11. In this exercise, you will design various classes and write a program tocomputerize the billing system of a hospital.a. Design the class doctorType, inherited from the class personType,defined in Chapter 10, with an additional data member to store adoctor’s speciality. Add appropriate constructors and member functionsto initialize, access, and manipulate the data members.b. Design the class billType with data members to store a patient’sID and a patient’s hospital charges, such as pharmacy charges formedicine, doctor’s fee, and room charges. Add appropriate constructorsand member functions to initialize, access, and manipulate thedata members.c. Design the class patientType, inherited from the classpersonType,defined in Chapter 10, with additional data membersto 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 datewhen the patient was discharged from the hospital. (Use the classdateType to…
I have the basis of a program that works as an inventory, it reads the contents of a file and displays them and their quantity in three places, listed below are the things that I need to add to the program below.

Double Bubble For this exercise you need to create a Bubble class and construct two instances of the Bubble object. You will then take the two Bubble objects and combine them to create a new, larger combined Bubble object. This will be done using functions that take in these Bubble objects as parameters. The Bubble class contains one data member, radius_, and the corresponding accessor and mutator methods for radius_, GetRadius and SetRadius. Create a member function called CalculateVolume that computes for the volume of a bubble (sphere). Use the value 3.1415 for PI. Your main function has some skeleton code that asks the user for the radius of two bubbles. You will use this to create the two Bubble objects. You will create a CombineBubbles function that receives two references (two Bubble objects) and returns a Bubble object. Combining bubbles simply means creating a new Bubble object whose radius is the sum of the two Bubble objects' radii. Take note that the CombineBubbles function…
(a) Write the cinema class that contains two private data: one to hold cinema location and the other to hold the number of seats in cinema. (b) Write the constructor foe the class that takes two parameters to set the location and the number of seats.
PLEASE HELP: In c++ please The class function needs to be in a header file (.h) The main needs to be on the main .cpp file. Please try to avoid using -> operators. Looking for a solution without them. Any help is very much appreciated. Much thanks! Create a class AccessPoint with the following attributes: x - a double representing the x coordinate y - a double representing the y coordinate range - an integer representing the coverage radius status - On or Off Add constructors. The default constructor should create an access point object at position (0.0, 0.0), coverage radius 0, and Off. Add accessor and mutator functions: getX, getY, getRange, getStatus, setX, setY, setRange and setStatus. Also, add a set function that sets the location coordinates and the range. Add the following member functions: move and coverageArea. Add a function overlap that checks if two access points overlap their coverage and returns true if they overlap. Add a function signalStrength that returns the…
ll data members must be declared as private. Global variables are not allowed. Constants are ok. There should be no usage of cin or cout in the method or in the class definition or required functions. They should be handled using parameters and return values. cin and cout can and should be used in the testing functions. There should be only one “return” statement in a function or method. Multiple return statements within the same function/method are not allowed. Please pay attention to the required data types in the description. tuple, list and vector classes are not allowed to be used in this exam. Please write C++ functions, class and methods to answer the following questions. 1. Define a new C++ class named “Exam” that manages simple exam information: student id (integer) and a score (integer) The class must provide at least the following two methods: • isPassing which will return a boolean: true if the score is >=60 and false otherwise • toString method that returns the string…
