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.

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)
Write a class result that has array of three integers as attribute. It has a member function to input and a member function to display average of elements. Create another class student that contains object of class result. It has additional attributes of roll number and name. It also has member functions to input and display data members
The Critter class is a base class with some basic functionality for running simulations of different kinds of critters. Critters can move, act, and remember their history. A typical simulation contains a number of critters of different types. In each step of the simulation, the act member function will be called on each critter. Define a class Sloth derived from Critter that simulates a sloth. Sloths alternate between eating and sleeping. Add the word "eat" or "sleep" to the history each time the act function is called. The implementation of the Critter class is not shown. Complete the following file: sloth_Tester.cpp #include <iostream>using namespace std; #include "critter.h" /**A sloth eats and sleeps.*/class Sloth : public Critter{public:Sloth();. . .private:. . .}; Sloth::Sloth(){. . .} void Sloth::act(){if (...) {add_history("eat");...}else{add_history("sleep");... }} int main(){Sloth sloth;sloth.act();cout << sloth.get_history() << endl;cout <<…
Using the attached diceType, create a class rollType that holds information for a roll of several dice simultaneously. rollType should contain the number of dice being rolled and a pointer to a dynamic array of diceType. (2) Create a client program to test your implementation that creates a dice roll whose size is based on the user's input. Step 1: Define remaining member functions Step 2: Complete test program Notes: DO NOT modify anything in diceType.h or diceTypeImp.cpp. **I just need your best guess at filling in the stub functions for this assignment and an updated test file. It doesn't have to be all that correct. I've attached the two diceType files as images. Only the rollDice ones need altering.** //diceRollType header file #ifndef DICE_ROLL_TYPE_H#define DICE_ROLL_TYPE_H #include "diceType.h" class diceRollType {public:void getResults() const;void rollDice() const; diceRollType(int = 1);~diceRollType();diceRollType(const diceRollType &otherDice); private:diceType…
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++)
Class student contains roll number, name and course as data members and Input_studentand display_student as member functions. Create a class exam and publicly inherit it fromstudent class. The derived class contains an array of marks and no_of_subjects as datamembers, and input_marks and display_result as member functions. Overload “<=”, “()” and“+=” operators and use the overloaded operators in the main function. Create an array ofobjects of the exam class and display the result of 5 student
Write a base class Computer that contains data member of wordSize (in bits), memorySize (in megabytes), storageSize (in megabytes) and speed (in megaHertz). Drive a Laptop class that s a kind of Computer but also specifies the objects length, width, height and weight. Member functions both classes should include a default constructor, a constructor to initialize all components and a function to display data members.
Create an employee class, basing it on previous lab. The member data should comprise an int for storing the employee number, a string for storing the name and a float for storing the employee’s salary. Member functions should allow the user to enter this data and display it. Write a main () that allows the user to enter data for three employees and display it do it by using scope resolution operator and pointer object.

Define two classes A and B each having one String private data member. Write zero argument and parameterized constructors to initialize the data member and member functions to get, set and display the data member for these classes. In the demo class, write a concat() function which takes the 2 arguments as class A and class B objects and concatenates the data ac members of these two objects. Write main method that creates instances of the classes A and B, assigns values to each and concatenates the value of data member of these objects using the concat() function. Display the objects before and after concatenation.
