This 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…
What are the similarities between structs and classes? (Select all that apply) - Private data members cannot be accessed outside of the class or struct -A default constructor will always be provided in both structs and classes to allow objects to be constructed -In both cases, objects are instances containing values -Operator == can be used to compare either struct or class variables of the same type -Operator = can assign variables of the same type by copying the values on the right to the object on the left -Variables of type struct or class that are declared in a function can be a return value for the function.
In C++ by using all header files and source files construct this: Create a Human class with the following features: Each Human needs a name, an age, and some phrase that they say. Each Human needs appropriate getters and setters for all attributes. For every interaction with this human, increment the age by 1 year. Default constructor with no arguments. Constructor that takes name, age, and phrase arguments. Create a driver to demonstrate all of the features of your Human class. The driver is the only class with main().The driver must create a dynamic array of Human Objects of some user defined size. This requires prompting the user for a number of Humans to create.Be sure to iterate through your array of Humans. Interact with every Human object. Demonstrate ALL features of the Human class. The Human class must to be defined in a header file with no implementation. Additionally, create an implementation file with all of the Human implementation code.

Consider the following declarations: (1, 2, 5, 7) How many members does class foodType have? How many private members does class foodType have? How many constructors does class foodType have? How many constant functions does class foodType have? Which constructor is used to initialize the object fruit1? Which constructor is used to initialize the object fruit2? Rewrite the definition of the class foodType so that each data member can be set individually. Write a C++ statement to replace the definition of the constructors with a constructor with default parameter.
you will design various classes and write a program to computerize the billing system of a hospital.a. Define a class personType having members of id, name, cnic. Define overloaded constructor,getter/setters and destructor.b. Design the class doctorType, inherited from the class personType, with an additional data member to store a doctor’s speciality. Add appropriate constructors and member functions to initialize, access, and manipulate the data members.c. Design the class billType with data members to store a patient’s ID and a patient’s hospital charges, such as pharmacy charges for medicine, doctor’s fee, and room charges. Add appropriate constructors and member functions to initialize and access and manipulate the data members.d. 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…
Create a class named 'Member' having the following members using C++:Data members 1 - Name 2 - Age 3 - Phone number 4 - Address 5 - Salary It also has a method named 'printSalary' which prints the salary of the members. Two classes 'Employee' and 'Manager' inherits the 'Member' class. The 'Employee' and 'Manager' classes have data members 'specialization' and 'department' respectively. Now, assign name, age, phone number, address and salary to an employee and a manager by making an object of both of these classes and print the same.
Model a room class, whose member data is three integers length, width and height. The classcontains two constructors to initialize the room class objects, first is no argumentconstructor, while the second in three arguments constructor. Class also contains threemember functions i.e., getdatat) to get the data from user and store in the memory of callingobject and showdata) to show the room data of calling object, int volume(int I, int w, int h)function should receive the length, width and height values from the objects one by one andreturn the volumes of the three objects respectively.Write a main program to declare the three object rl, 12, and 13 of room class. Two objectwill store the values through three argument constructor and third object will get the datafrom user by calling getdata function. Then all three objects should call the volumefunctions to calculate their volumes and store them in three variables of type integer. Finallythe system compare the three volumes values…
Write a Fraction class whose objects will represent fractions. Note: this is the first part of a multi-part assignment. For this week (1) do not reduce fractions, (2) do not use "const," (3) do not provide any constructors, and (4) do not use three separate files. These are topics we will study next week. You will not receive credit for the assignment if you do any of these things. In your single file, the class declaration will come first, followed by the definitions of the class member functions, followed by the client program. You must provide the following member functions: A set() operation that takes two integer arguments, a numerator and a denominator, and sets the calling object accordingly. Arithmetic operations that add, subtract, multiply, and divide Fractions. These should be implemented as value returning functions that return a Fraction object. They should be named addedTo, subtract, multipliedBy, and dividedBy. In these functions you will need to declare a local…
