Create a class called integerset. A set is represented initially as an array of ones and zeros. a[i] is 1 if integer number i is in the set, and 0 if the integer number i is not in the set. An object is instantiated by passing to the constructor an integer representing the range of the set. For a set of integers from 0 to 19 is instantiated as integerset a(20); the default constructor is used also. An array containing the appropriate number of elements is allocated dynamically and initialized by the constructor. Provide Public member functions for the common set operations (union – intersection), print a set as a list of numbers separated by spaces, Print --- for empty set, equalto member function that determine if two sets are equal in elements, and final lessthan member function that determine the set is less than other set in the elements. Include any additional operations that you think would be useful for a complex number class.

Write a C#program that uses a class called ClassRegistration as outlined below: The ClassRegistration class is responsible for keeping track of the student id numbers for students that register for a particular class. Each class has a maximum number of students that it can accommodate.   Responsibilities of the ClassRegistration class: It is responsible for storing the student id numbers for a particular class (in an array of integers) It is responsible for adding new student id numbers to this list (returns boolean) It is responsible for checking if a student id is in the list (returns a boolean) It is responsible for getting a list of all students in the class (returns a string). It is responsible for returning the number of students registered for the class (returns an integer) It is responsible for returning the maximum number of students the class is allowed (returns an integer) It is responsible for returning the name of the class. (returns a string)   ClassRegistration -…

Create a class: “Question 1” with data members: 1D integer array of maximum size: 100, n(int). Create a dynamic constructor which takes input of n and n no. of array elements. Apartfrom taking input this class also displays the maximum and minimum elements from the givenarray elements.

Define a class called Book. This class should store attributes such as the title, ISBN number, author, edition, publisher, and year of publication. Provide get/set methods in this class to access these attributes. Define a class called Bookshelf, which contains the main method. This class should create a few book objects with distinct names and store them in an ArrayList. This class should then list the names of all books in the ArrayList. Enhance the program by providing a sort function, which will sort the books in ascending order of their year of publication. Create a few more Bookobjects with the same names but with different edition numbers, ISBNs, and years of publication. Add these new Book objects to the ArrayList, and display the book list sorted by book name; for duplicate books of the same name, sort the list by year of publication. (Hint: You will need to define a comparator class that takes two Book objects as parameters of the compareTo This method should do a two-step…
