The AeroCar class inherits from the Car class and overrides the set_speed (double new_speed) function. In the AeroCar set_speed function, how can the Car set_speed function be called? Car::set_speed() ::set_speed(new_speed) O Car::set_speed(new_speed) The Car set_speed function cannot be called from the AeroCar::set_speed function. B

IN C++ Lab #6: Shapes Create a class named Point. private attributes x and y of integer type. Create a class named Shape. private attributes: Point points[6] int howManyPoints; Create a Main Menu: Add a Triangle shape Add a Rectangle shape Add a Pentagon shape Add a Hexagon shape Exit All class functions should be well defined in the scope of this lab. Use operator overloading for the array in Shape class. Once you ask the points of any shape it will display in the terminal the points added.
User-defined Class:You will design and implement your own data class. The class will store data that has been read asuser input from the keyboard (see Getting Input below), and provide necessary operations. As thedata stored relates to monetary change, the class should be named Change. The class requires atleast 2 instance variables for the name of a person and the coin change amount to be given to thatperson. You may also wish to use 4 instance variables to represent amounts for each of the 4 coindenominations (see Client Class below). There should be no need for more than these instancevariables. However, if you wish to use more instance variables, you must provide legitimatejustification for their usage in the internal and external documentation.Your class will need to have at least a default constructor, and a constructor with two parameters:one parameter being a name and the other a coin amount. Your class should also provide appropriateget and set methods for client usage. Other…
build a student class implement the student class with the following instance variables: * id * firstName *lastName *dateOfBirth * Major create an __init__ function adn initialize all the fields make the "major" an option field and set a default value to "undefined" create a setter and getter function for all these five variables create another function: "print_student_info()" which prints 5 pieces of information: id, first name, last name, date of birth, and major. Make sure to have proper formatting done for printing these 5 things. Use the student class Task 1: create an empty list named "all_students" Task 2: create a variable named "id" and initialize it to 100 (some default value to start with, next id would be 101) Task 3: ask the user for input "How many students:" Task 4: Now run a for loop based on that input number and do the following things for each iteration: - get input of student's first name, last name, date of birth, and major - user should be able to skip the…
In c++ The student class defines the strings studName and studSSN as protected data members. Aconstructor has arguments that initialize the data. The class studentAthlete has a private datamember sport, which describes the sport the student plays. Both classes have a memberfunction identify(). The base class student outputs the student information in the form student studName Social Security Number studSSN The function in the base class should support polymorphism, and the function in the derivedstudentAthlete class should add the information “Sport <sport>”. In the file “student.h”,declareand implement the two classes in an inheritance hierarchy. In a program, initialize an array of five student pointers as follows: student ja(“John Anderson”, “345-12-3547”);student bw(“Bill Williams”, “286-72-6194”);studentAthlete bj(“Bob Johnson”, “294-87-6295”, “football”);studentAthlete dr(“Dick Robinson”, “669-28-9296”, “baseball”); // list of student pointersstudent *stud[] = {&ja,…
Write a program to create a class teacher with the following data members.ID: Can be accessed only from the teacher class and derived classes of the teacher.Age: Can be accessed from all the classes and packages in the application.Phone Number: Can be accessed only from the classes inside the same package.Write the constructor function. Derive a class Math_teacher from the teacher class, add the following two data members in the Math_teacher class.Room Number: This can be accessed by all the classes in the application.Course_ID: This can be accessed by all the classes in the same package.Write the constructor function.

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
in c++ Define another new class named “GradStudent” that must inherit from the Student class. This GradStudent class will manage the following info: id, name, gpa and graduation year (integer). This class should allow to create a GradStudent object with or without a given graduation year. If the year is not given, it will default it to 2021. Its toString() method should return a string with the graduation year info such as ID(3000) NAME(Nancy Brown) GPA(3.50) GRADUATION-YEAR(2021)
In previous chapters, you have created programs for the Greenville Idol competition. Now create a Contestant class with the following characteristics: The Contestant class contains public static arrays that hold talent codes and descriptions. Recall that the talent categories are Singing Dancing, Musical instrument, and Other. The class contains an auto-implemented property that holds a contestants name. The class contains fields for a talent code and description. The set accessor for the code assigns a code only if it is valid. Otherwise, it assigns I for Invalid. The talent description is a read-only property that is assigned a value when the code is set. Modify the GreenvilleRevenue program so that it uses the Contestant class and performs the following tasks: The program prompts the user for the number of contestants in this years competition; the number must be between 0 and 30. The program continues to prompt the user until a valid value is entered. The expected revenue is calculated and displayed. The revenue is $25 per contestant. The program prompts the user for names and talent codes for each contestant entered. Along with the prompt for a talent code, display a list of the valid categories. After data entry is complete, the program displays the valid talent categories and then continuously prompts the user for talent codes and displays the names of all contestants in the category. Appropriate messages are displayed if the entered code is not a character or a valid code.
