- a class can be instaniated from an object (true/false) we use pointer variable to reference objects stored in the heap memory (true/false) a class diagram can only be implemented using C++ (true/false)Accomplish the following for the given class diagram. Elevator 1. Create the class implementation using C++ upDirection 2. Create one object from class Elevator and store it in the stack memory. 3. Create one object from class Elevator and store it in the heap memory. 4. Test all the functions of the two objects • currentFloor: int • move (numFloors : int): void stop (): void + status (): stringCircular Queue: A circular queue is the extended version of a regular queue where the last element is connected to the first element. Thus forming a circle-like structure. Create a C++ generic abstract class named as CircularQueue with the following: Attributes: Type*arr; int front; int rear; int maxSize; Functions: virtual void enqueue(Type) = 0; Adds the element of type Type at the end of the circular queue. virtual Type dequeue() = 0; Deletes the first most element of the circular queue and returns it. PLEASE USE C++
- Design a C class Student Log that prints a log of all operations in its object's life cycle i.e print CREATED, COPIED, ACCESSED, MUTATED, and DESTROYED when an object of the class is created, copied, its value read, its value changed, and object destroyed respectively. Student class stores name, roll no, and marks in 5 subjects (use appropriate data types). Use the concepts of constructor and destructors Write a menu-driven C program that creates a Student Log object studobj and performs operations on it. Your program should repeatedly read a character from the user and do the following: R- Read name and rollno into studobj from the user M - Read 5 integers from the user and Set marks C - Check whether the student passes (gets 50% marks). Print "PASS/FAIL" X - Exit the program INPUT FORMAT R Shyam CB.EN.2013456CSE M 32 24 45 12 9 C X OUTPUT FORMAT: CREATED MUTATED MUTATED ACCESSED FAIL DESTROYEDThe programmer constructs a class to isolate the functionality of an implementation from the kind of data utilized in it. As a result, every data type may be accommodated by functions and classes. o file with headers o technique that is virtual O design template a generic classAccomplish the following for the given class diagram. Course 1. Create the class implementation + courseName: string + courseld: int using C++ 2. Create two objects from class Course and store it in the stack + viewCourse (): void modifyCourse (newCourse : string): void memory. 3. Test all the functions of the two removeCourse() (): bool + createCourse (): bool objects
- Question Make Class Diagram And Use Case Diagram The system Description Title: Working student's system The objective of the system is to create and manage a generic working domain for any student through his/her computer at Oryx college. A user should be able to organize the working space by a tree of topics corresponding to his/her activities in a recursive way. Each topic should have a name, a short description, and if needed a list of links to folders, files or the web. A topic is either a terminal or a non-terminal. If the topic is not terminal then it should be related to other topics. Any terminal or non-terminal topic should be related to its parent and possibly horizontally to other topics in the network of topics in a symmetric way. By using the generic built structure, the system should be illustrated and used for student work organization, which goal is to minimize the browsing time used by the student to manage his/her documents, by adding, removing, reading, any target…Object oriented programming C++ Use Classes Write a C++ program in which each flight is required to have a date of departure, a time of departure, a date of arrival and a time of arrival. Furthermore, each flight has a unique flight ID and the information whether the flight is direct or not.Create a C++ class to model a flight. (Note: Make separate classes for Date and Time and use composition).add two integer data members to the Flight class, one to store the total number of seats in the flight and the other to store the number of seats that have been reserved. Provide all standard functions in each of the Date, Time and Flight classes (Constructors, set/get methods and display methods etc.).Add a member function delayFlight(int) in the Flight class to delay the flight by the number of minutes pass as input to this function. (For simplicity, assume that delaying a flight will not change the Date). Add a member function reserveSeat(int) which reserves the number of seats passed as…Using c++ create a class with a static member item so that when ever a new object is created the total number of objects of the class can be reported.
- An Abstract Data Type (ADT) is: A. same as an abstract class B. a data type that cannot be instantiated C. a data type for which only the operations defined on it can be used, but none else D. all of the above7. Dynamic MathStack The MathStack class shown in this chapter has only two member functions: add and sub. Write the following additional member functions: Function Description mult Pops the top two values off the stack, multiplies them, and pushes their product onto the stack. div Pops the top two values off the stack, divides the second value by the first, and pushes the quotient onto the stack. addAll Pops all values off the stack, adds them, and pushes their sum onto the stack. multA11 Pops all values off the stack, multiplies them, and pushes their prod- uct onto the stack. Demonstrate the class with a driver program. here is the extention file please use it. // Specification file for the IntStack class #ifndef INTSTACK_H #define INTSTACK_H class IntStack { private: int *stackArray; // Pointer to the stack array int stackSize; // The stack size int top; // Indicates the top of the stack public: // Constructor IntStack(int); // Copy constructor…3 - Write a class in C++ language contain three objects to illustrate the concept of Destructor.
