Below is some code for a rectangle class that needs to be completed. Add member function declarations to the class declaration and member function definitions below the declaration. For the accessor functions, you can add the definitions directly into the class declaration. The goal is to code the class so that it works wthout changing the main program #include <iostream>using namespace std; // rectangle has a vertical height and horizontal width// The class below is a rectangle. It has two private// data members: height and width.// TODO: Complete the class declaration and definition.class rectangle {public:// TODO: declare a default constructor// Make the height and width = 1. // TODO: declare member function void add// @param int height, int width // TODO: delcare member function void set// @param int height, int width // TODO: declare member function void draw // TODO: define accessor for width // TODO: define accessor for height private:int width;int height;}; // TODO:…
c++ Build a class Sale with private member variablesdouble itemCost; // Cost of the itemdouble taxRate; // Sales tax rateand functionality mentioned below:● Write a default constructor to set the member variable itemCost to 0 andtaxRate to 0. ● Write a parameterized constructor that accepts the parameter for eachmemberSale( double cost, double rate) ● Generate only accessors for itemCost and taxRate● Write a function double getTax( ) to calculate tax i.e take a product ofitemCost and itemRate. ● Write a function double getTotal( ) to calculate the total price of itemi.e. take a sum of itemCost and getTax( ) (calling getTax() will returnthe calculated tax on item).
Assume a class named Dollars exists. Write the headers for member functions that overload the prefix and postfix ++ operators for that class.
write a c++ in which you vreate a class Point. This class have four member variables, a,b,c,d. Write the following member functions drawTriangle(int x, int y, int z ) and drawRectangle(int x, int y, int z, int a). Each function should calculate the length of lines and calculate circumference for each of the shape (triangle, rectangle). example triangle should calculate length of its three lines and then calculate circumference. such as, Note: the number of lines depends on the name of shape.void drawTriangle(int x, int y, int z ){int line 1 = x - y; // convert to positive value if line 1 is negativeint line 2 = y -z; int line 3 = z -x; cout<< the circumference of triangle is << //// here write formula to calculate circumference of triangle and display output of circumference}Write similar code for drawRectangle(int x, int y, int z, int a). write main function to callthese three functions to display output.b. write another function drawLine(int x, int y) in the above code.…
create two classes named mammals and marine animals. create another class named blue whale which inherits both the above classes.now, create a function in each of these classes which prints "I am mammal", "I am marine animal" and "I belong to both the categories: mammals as well as marine animals "respectively. now, create an object for each of the above class and try calling function of a mammal by the object of mammal function of blue whale by the object of blue whale function of each of its parent by the object of blue whale function of marine animal by the object of marine animal
Part 1:Create a class DateType that has the following member variables: day (int), month(int), and year(int). - Your class should have the following member functions:o Parametrized default constructor.o Destructoro A get function for each member variables- Your class should also have the following friend functions:o Overload insertion operator to print date to screeno Overload extraction operator to read date from userPart 2:Create a class PersonType that has the following member variables: id(int), name(string), birthdate (DateType), and gender (char). - Your class should have the following member functions:o Parametrized default constructor.o Destructor.o A get function for each member variableso Overload == operator to check if two persons have equal ids or not.- Your class should also have the following friend functions:o Overload insertion operator to print person info to screeno Overload extraction operator to read person info from user
(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.
Assume the definition of class foodType as given in Exercise 6. Answer the following questions? (1, 2, 3, 5, 6) Write the definition of the member function set so that private members are set according to the parameters. The values of the int and double instance variables must be nonnegative. Write the definition of the member function print that prints the values of the data members. Write the definitions of the member functions getName, getcalories, getFat, getSugar, getCarbohydrate, getPotassium to return the values of the instance variable. Write the definition of the default constructor of the class foodType so that the private member variables are initialized to 0, 0. 0, 0, 0. 0, 0. 0, respectively. Write the definition of the constructor with parameters of the class foodType so that the private member variables are initialized according to the parameters. The values of the int and double instance variables must be nonnegative. Write a C + + statement that prints the value of the object fruit 2. Write a C++ statement that declares an object my Fruit of type foodType, and initializes the member variables of myFruit to Apple, 52, 0. 2, 10,13.8, and 148.0, respectively.
Create a class called time that has separate int member data for hours, minutes, and seconds. One constructor should initialize this data to 0, and another should initialize it to fixed values. Another member function should display it, in 11:59:59 format. Includes an overloaded decrement (--) operator that operates in both prefix and postfix notation and return values. Add statements to main () to test these operators.
