Create a class named Student that has three member variables: name – A string that stores the name of the student numClasses – An integer that tracks how many courses the student is currently enrolled in classList – A dynamic array of strings used to store the names of theclasses that the student is enrolled in Write appropriate constructor(s), mutator, and accessor functions for the classalong with the following: • A function that inputs all values from the user, including the list of class names.This function will have to support input for an arbitrary number of classes. • A function that outputs the name and list of all courses. • A function that resets the number of classes to 0 and the classList to anempty list. • An overloaded assignment operator that correctly makes a new copy of the listof courses. • A destructor that releases all memory that has been allocated.

This is an object oriented programming question The code should be in C++ language Create a class Student having a private data members S_ID, S_Name and S_CGPA. Now create a public member functions void getID(), void getName() and getCGPA() and finally to display all the data members, create a function void display(). In the main(), create an array of student class, size of the array should be taken from user at run time and call all the functions defined in the class.

(Polynomial Class) Develop class Polynomial. The internal representation of a Polynomialis an array of terms. Each term contains a coefficient and an exponent, e.g., the term2x4has the coefficient 2 and the exponent 4. Develop a complete class containing proper constructorand destructor functions as well as set and get functions. The class should also provide the followingoverloaded operator capabilities:a) Overload the addition operator (+) to add two Polynomials.b) Overload the subtraction operator (-) to subtract two Polynomials.c) Overload the assignment operator to assign one Polynomial to another.d) Overload the multiplication operator (*) to multiply two Polynomials.e) Overload the addition assignment operator (+=), subtraction assignment operator (-=),and multiplication assignment operator (*=).
array of Payroll ObjectsDesign a PayRoll class that has data members for an employee’shourly pay rate and number of hours worked. Write a program withan array of seven PayRoll objects. The program should read thenumber of hours each employee worked and their hourly pay ratefrom a file and call class functions to store this information in theappropriate objects. It should then call a class function, once foreach object, to return the employee’s gross pay, so this informationcan be displayed.
Create a class for smart pointers. A smart pointer is a data type that simulates a pointer and offers automated garbage collection. It is often implemented using templates. When the number of references to a SmartPointerT*> object drops to zero, the object of type T is immediately released.
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

create using c++ One problem with dynamic arrays is that once the array is created using the new operator the size cannot be changed. For example, you might want to add or delete entries from the array similar to the behavior of a vector . This project asks you to create a class called DynamicStringArray that includes member functions that allow it to emulate the behavior of a vector of strings. The class should have the following A private member variable called dynamicArray that references a dynamic array of type string. A private member variable called size that holds the number of entries in the array. A default constructor that sets the dynamic array to NULL and sets size to 0. A function that returns size . A function named addEntry that takes a string as input. The function should create a new dynamic array one element larger than dynamicArray , copy all elements from dynamicArray into the new array, add the new string onto the end of the new array, increment size, delete the…
Create a class Department with attributes DName, DID, a dynamic listDTeachers of type string.Write accessors and mutators for all data membersand show function to show all data members.Create nullaryand parameterized constructors to initialize the data members.Also write a copy constructor for Department class.In main() create a dynamic array of departments, Use loop to create four objects in the dynamic array. All the even indexed objects should be created with nullary constructors and thencall the accessors and mutators to initializethe objects while, all the odd indexed objects should be initialized using parameterized constructors. Create four copy objects from array using copy constructors.Call the show function to show the four objects.
Smart Pointer: Write a smart pointer class. A smart pointer is a data type, usually implemented with templates, that simulates a pointer while also providing automatic garbage collection. It automatically counts the number of references to a SmartPointer<?> object and frees the object of type T when the reference count hits zero.
