first, define the rectangle class which has two functions for calculating area and perimeter. then write a c++ program that in its main function has 2 square objects and calculate their area and perimeter. for each object ask the user to give you the sides. in your class definition write a comment to tell which function is mutator, which function is accessor, which one is the constructor.
(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.
Mark the following statements as true or false. The member variables of a class must be of the same type. (1) The member functions of a class must be public. (2) A class can have more than one constructor. (5) A class can have more than one destructor. (5) Both constructors and destructors can have parameters. (5)
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. 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.
Problem: Create a Fraction class with two private positive integer member variables numerator and denominator, one constructor with two integer parameters num and den with default values 0 and 1, one display function that print out a fraction in the format numerator/denominator in the proper form such as 2/3 or ½ . Note: 2/4 should be displayed as ½.

In this assignment, the class declaration should come first, followed by the definitions of the class member functions, followed by the client program. #include <iostream> using namespace std; class Fraction { private: int numerator; int denominator; public: void set(int n,int d){ numerator=n; denominator=d; } int getNumerator(){ return numerator; } int getDenominator(){ return denominator; } Fraction addedTo(Fraction& r){ int a=this->numerator; int b=this->denominator; int c=r.numerator; int d=r.denominator; int e,f; e=(a*d+b*c); f=b*d; Fraction f1; f1.set(e,f); return f1; } Fraction subtract(Fraction& r){ int a=this->numerator; int b=this->denominator; int c=r.numerator; int d=r.denominator; int e,f; e=(a*d-b*c); f=b*d; Fraction f1; f1.set(e,f); return f1; } Fraction multipliedBy(Fraction& r){ int a=this->numerator; int b=this->denominator; int c=r.numerator;…
Write an OOP program in C++, which contains three, classes i.e. Parent Class, Child1 Class & Child2 Class. Parent Class inherited within Child1 Class & Child2 Class. Parent Class has one member function that is Public: void Show( );. Child1 & Child2 Class will follow the signature of the Parent Class member function; each class will have different function definitions. And during running time a message will be displayed that which class object you want to create to call their member function as shown in the output below. For Example: if enter 1 then it will call parent class function If enter 2 then it will call child1 class function If enter 3 then it will call child2 class function. Hint: Solve this Program using Run Time Polymorphism.

C++YOU ONLY NEED TO EDIT date.h, dateOFYear.h, and dateOFYear.cpp date.h | date.cpp | dateOfYear.h | dateOfYear.cpp | dateTest.cpp You have been provided a Date class. Each date contains day and month parameters, a default and a custom constructor, mutator and accessor functions for the parameters, and input and output functions called within operator >> and <<. You will be writing a DateOfYear class, which expands on the Date class by adding a year parameter. This will be achieved via inheritance – DateOfYear is the derived class of the Date base class. In DateOfYear, will need to write… The include guards for the class A default constructor that initializes all parameters to 1 A custom constructor that takes in a month, day, and year to initialize the parameters Mutator and accessor for the year parameter Redefined versions of inputDate and outputDate that takes into account the new year parameter. The driver program, dateTest.cpp, is already set for use with both Date…
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. I've included a photo of how the program currently runs. 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…
Create a class called Name that contains data members of type string called first name, middle name, last name, and salutation. Add a constructor that takes four parameters which are used to initialize the four data members and a member function called to-string that returns the person's full name in the form of “Salutation First name Middle name Last name”. Finally add set and get functions for all the data members. Add a destructor to the program displaying a suitable msg.
