FeetInches Class Copy Constructor and multiply Function
Add a copy constructor to the FeetInches class. This constructor should accept a FeetInches object as an argument. The constructor should assign to the feet attribute the value in the argument’s feet attribute, and assign to the inches attribute the value in the argument’s inches attribute. As a result, the new object will be a copy of the argument object.
Next, add a multiply member function to the FeetInches class. The multiply function should accept a FeetInches object as an argument. The argument objects feet and inches attributes will be multiplied by the calling object’s feet and inches attributes, and a FeetInches object containing the result will be returned.

- Object passing checklist1. Go over each member function and add the const keyword after their declaration ifthey do not modify any of the class' member variables.2. When accepting objects as parameters, prefer to pass them by reference. Add areference declarator (&) before the identifier name of an object parameter.3. If the member function does not modify the parameter, make the parameter constantby using the const keyword. apply the Object Passing Checklist. Modify food.h and volunteer.h to useobject references. Add const and & keywords in the appropriate places of the code.arrow_forwardCircle Class (Easy) Write a Circle class that has the following member variables: radius : a double The class should have the following member functions: Default Constructor: default constructor that sets radius to 0.0. Constructor: accepts the radius of the circle as an argument. setRadius: an mutator function for the radius variable. getRadius: an accessor function for the radius variable. getArea: returns the area of the circle, which is calculated as area = pi * radius * radius getCircumference: returns the circumference of the circle, which is calculated as circumference = 2 * pi * radius Step1: Create a declaration of the class. Step2: Write a program that demonstrates the Circle class by asking the user for the circle’s radius, creating Circle objects, and then reporting the circle’s area, and circumference. You should create at least two circle objects, one sets the radius to 0.0 and one accepts the radius as an…arrow_forwardPlease read the main function and define a class CStudent. (object array, static member, string) Please do not change the main function and complete the program given. 【Description】 Please read the main function and define a class CStudent. In the main funciton, two arrays of the ojbect of CStudent are define. Please analyze the call of constructor and destructor in the process of creating and releasing objects. 1. CStudent has two private member variables:stirng name, int age. 2. CStudent has a static member count. It will be incremented by 1 when the object is created and decremented by 1 when the object is destroyed. 3. The constructor function should output "*** is contructing". The destructor function should output “*** is destructing”. "***" indicates the name of the current CStudent object. 【Input】 No input 【Output sample】 There are 0 students. noname is contructing noname is contructing noname is contructing noname is contructing noname is contructing name:noname…arrow_forward
- Create an Employee class that includes three private data members— firstName (type string), lastName (type string), and monthlySalary (type int ).It also includes several public member functions.1. A constructor initializes the three data members. 2. A setFirstName function accepts a string parameter and does not return any data. It sets the firstName.3. A getFirstName function does not accept any parameter and returns a string. It returns the firstName.4. A setLastName function accepts a string parameter and does not return any data. It sets the lastName.5. A getLastName function does not accept any parameter and returns a string. It returns the lastName.6. A setMonthlySalary function accepts an integer parameter and does not return any data. It sets the monthlySalary. If the monthly salary is less than or equal zero, set it to 1000 and it displays the employee’s first name, last name and the inputted salary with a statement “**==The salary is set to $1000.”7. A getMonthlySalary…arrow_forwardTrue/False: a member function in a class can access all of its class's member variables, but not if the variables are protected.arrow_forwardCreate an overloaded > (greater than) operator in the Student class. The operator will compare the age of two student objects and return the object with the greater age. In main.cpp create a non member function named isFemale. This function will receive as parameter a pointer to a student object. If the last two numbers of the student number is valid numbers (Must be between 0 and 9) the function will return true. Otherwise the function will return false. How to do this part ?, I'm lost The student.h file is below.arrow_forward

A) True B) Falsearrow_forwardDesign a class called Bird that includes three pieces of information as data members-name (type string), species (type string) and a sizeInInches (type int).Define virtual function getCageSize ().Your class should have a constructor that initializes the three data members. Provide setter and getter function for each data member.Overload the virtual function of inherited class. Write a main part which creates the Bird class and a derived class Vulture.arrow_forward
- (C++) 23. True/False: function getGallons() is an inline member function 24. Design a class called Date. The class should store a date in three private integers: month, day, year. There should be a member function to print out the date in the month/day/year format, e.g. 12/25/2015, 4/1/1970 There should be a constructor which takes three parameters to initialize the date. It should not accept values for day greater than 31 or less than 1, or values for month greater than 12 or less than 1. If the constructor is called with these values an error message should be printed out and the field set to 0. Any value for year is acceptable. There do not need to be any other member functions. Provide the class declaration and also the implementation of the member function and constructor.arrow_forwardDefine a Pet class that stores the pet’s name, age, and weight. Add appropriateconstructors, accessor functions, and mutator functions. Also define a functionnamed getLifespan that returns a string with the value “unknown lifespan.” Next, define a Dog class that is derived from Pet. The Dog class should have aprivate member variable named breed that stores the breed of the dog. Add mutator and accessor functions for the breed variable and appropriate constructors.Redefine the getLifespan function to return “Approximately 7 years” if the dog’sweight is over 100 pounds and “Approximately 13 years” if the dog’s weight isunder 100 pounds. Next, define a Rock class that is derived from Pet. Redefine the getLifespanfunction to return “Thousands of years.” Finally, write a test program that creates instances of pet rocks and pet dogs thatexercise the inherited and redefined functions. use c++arrow_forward. Write a class definition that creates a class called leverage with one private data member, crowbar, of type int and one public function whose declaration is void pry(). Write a member function called getcrow(). This function should return the value of the crowbar data. Assume the function is defined within the class definition.arrow_forward
