Create a class called ClassQuiz. ClassQuiz will maintain quiz grades for students in a class.

The class has the following member variables: int numStudents // holds the number of students in the class double* grades // to point to a dynamically allocated array of grades

The class has the following public functions: +default constructors //set numStudents = 0; and grades = nullptr; +parameterized constructors //accepts numStudents and creates an array with size = numStudents; +AcceptGrades // accept grades from end user using cin and stores them in grades array. +CalculateAverage //calculate and returns the average of the class. +Destructor to free the dynamically allocated array. +Any setters/getters needed. Note that a setter for the numStudents should also initialize grades array.

Main: Create an object of the ClassQuiz class. Call AcceptGrades to accept grades from user. Call CalculateAverage to calculate the average of the class. Print the class average.
