Create a base class called shape. Use this class to store two double type values that could be used to compute the area of figures. Derive two specific classes called triangle and rectangle from the base shape. Add to base class, a member function get data() to initialize base class data members and another member functions display_area() to compute and display the area of figures. Mark the display_area() as a virtual function and redefine this function in the derived class to suit their requirements.(Use pure virtual function)

Create a base class called shape. Use this class to store two double type values that could be used to compute the area of figures. Derive two specific classes called triangle and rectangle from the base shape. Add to the base class, a member function get_data() to initialize base class data members and another member function display_area() to compute and display the area of figures. Make display_area() as a virtual function and redefine this function in the derived classes to suit their requirements. Using these three classes, design a program that will accept dimensions of a triangle or a rectangle interactively, and display the area.Remember the two values given as input will be treated as lengths of two sides in the case of rectangles and as base and height in the case of triangles, and used as follows: Area of rectangle = x * y Area of triangle = ½ * x * y ( write the program in C++)
Write a class Travel having two private data members (distanceCovered , Time) The class has three constructors which are • having no parameter – for setting values to zero or null. • having two parameters for assigning values to both data members. • Overload the above constructor and use this keyword to set the values of data members. • Provide getters/setters for data members. • A function which calculates and display speed of traveling. • Write a function show() displays values. Write test Application that demonstrates the Run class by calling all the three constructors and method, creating a Create Travel objects, and then display the traveling with speed. Calculate highest speed. Programming language : java

Create a base class called shape, this class to store two double type values (value1, value2) that could be used to compute the area of figures. Derive two specific classes called triangle and rectangle from the base shape. Add accessor and mutator function to the base class, to initialize and retrieve base class data members and another member function display_area() to compute and display area of figures.. Make display_area as pure virtual function and provide its definition in the derived class to suit their requirements. Using these three classes, design a program that will accept dimensions of a triangle or a rectangle interactively and display area. Run the above program with following requirements. Provide appropriate constructor in each class. Use constructor function to initialize the data members of base class.
define a class named as rectangle having two data members named as base and height to store value of base and height. it contain a calculate function to calculate area of rectange. define another class with the triangle having two data members named as base and height to store value of base and height. it contain a calculate function to calculate area of triangle. define third class name as compare having a single function compare to compare values of both classes rectangle and triangle and display the area of maximum
In C++, Create a base class called shape. Use this class to store two double type values that could be usedto compute the area of figures. Derive two specific classes called triangle and rectangle from the baseshape. Add to the base class, a member function get_data() to initialize base class data members andanother member function display_area() to compute and display the area of figures. Makedisplay_area() as a virtual function and redefine this function in the derived classes to suit theirrequirements. Extend the above program to display the area of circles. This requires addition of a new derivedclass ‘circle’ that computes the area of a circle. Remember, for a circle we need only one value, itsradius, but the get_data() function in base class requires two values to be passed.(Hint: Make thesecond argument of get_data() function as a default one with zero value.)
1. Please read the main function and define a class CStudent. (object array, static member, string) 【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 There are 5 students. noname is destructing noname is destructing…
Create class distance that have (feet and inches) as float data members, and the following function members: • Constructor "parametrized". set: to input data. Print : to display ( feet and inches ) stored information as friend function . • Overload (-): operation to change the sign of distance object Using the previous class write a main program that will test this class functions for three objects.
Design a class bookType that defines a book as a class. a. Each object of the class bookType will hold the following information about a book: title number of authors up to four authors publisher year published ISBN 13 (with dashes) price number of copies in stock (may be 0) b. Include the member functions to perform the various operations on objects of type bookType: Include individual get and set functions for all member variables. c. Add a member function to update the number of copies in stock. d. Add the appropriate constructors and a destructor (if one is needed). Ensure a default constructor is coded and the constructor initializes all data members. Remember, an array of classes uses a default constructor only. e. ALL member variables must be private and accessed through member functions. The main client program CANNOT access the variables directly. f. Ensure the class declaration and class implementation files are in separate header and code (.cpp) files. This assignment will…

1- Create a class Rational for performing arithmetic with fractions.Write a driver program to test the class. Provide a constructor thatenables an object of this class to be initialized when it isinstantiated. The constructor should contain default values in caseno initializes are provided and should store the fraction in reducedform. Provide a private function to reduce numbers.Provide Public member functions for each of the followingarithmatic’s functions (addition – subtraction – multiplication –division), printing in the form a/b, printing in floating point formatand final overload the == and != operators to allow comparisons oftwo fraction numbers.Include any additional operations that you think would be useful fora rational number class.Design, implement, and test your class.
Define 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++
