True or false ?   Assuming class Quiz { public: void TakeIt ( ); }; Quiz cs2b_quiz; Quiz * p_quiz = & cs2b_quiz; The syntax to invoke TakeIt ( ) member function using the pointer is: p_quiz->TakeIt ( );

Write program in C++ Language The other solutions on chegg were incorrect! Please read carefully! Write a program that defines and tests a class called COP3014. The class resembles aclassroom. It has the following grading scheme:3 quizzes 20 points each 20%Mid term 100 points 30%Final 100 points 50%Based on the total grade of any student for the course, the letter grade of each student can becomputed as follows:Any grade of 90 or more is an A, any grade of 80 or more (but less than 90) is a B, any grade of70 or more (but less than 80) is a C, any grade of 60 or more (but less than 70) is a D, and anygrade below 60 is an F.This class needs to have some member variables. The first name, last name, the Z-number, thegrades, the total grade and final letter grade are all considered to be private member variablesof this class.The class should also have the following public member functions/procedural attributes that canbring the objects (students of the class) to life and give them some…

2. The MyInteger Class Problem Description: Design a class named MyInteger. The class contains: n [] [] A private int data field named value that stores the int value represented by this object. A constructor that creates a MyInteger object for the specified int value. A get method that returns the int value. Methods isEven () and isOdd () that return true if the value is even or odd respectively. Static methods isEven (int) and isOdd (int) that return true if the specified value is even or odd respectively. Static methods isEven (MyInteger) and isOdd (MyInteger) that return true if the specified value is even or odd respectively. Methods equals (int) and equals (MyInteger) that return true if the value in the object is equal to the specified value. Implement the class. Write a client program that tests all methods in the class.

C# languageCreate a class for “Plane” having functionalities (methods) startengine(), fly() and land(). When ever engine starts it should reset the attribute TTK (Total travel kilometer) to zero and attribute Fuel to 100. On fly() it should add 10 kilometers if the Fuel attribute is greater than zero and decrement Fuel by 20.On land() it should print total distance covered. Write the code providing all necessary details. And then show working object of Plane in main().

Classes, Objects, Pointers and Dynamic Memory Program Description: This assignment you will need to create your own string class. For the name of the class, use your initials from your name.  The MYString objects will hold a cstring and allow it to be used and changed. We will be changing this class over the next couple programs, to be adding more features to it (and correcting some problems that the program has in this simple version). Your MYString class needs to be written using the .h and .cpp format. Inside the class we will have the following data members: Member Data Description char * str pointer to dynamic memory for storing the string int cap size of the memory that is available to be used(start with 20 char's and then double it whenever this is not enough) int end index of the end of the string (the '\0' char) The class will store the string in dynamic memory that is pointed to with the pointer. When you first create an MYString object you should…
