- Write c# equivalent statements for the following: There is a book library. Define classes respectively for a library. The library must contain a name and a list of books (use array). The books only contain author name as information. In the class, which describes the library, create methods to add a book to the library, to search for a book by a predefined author, and to delete a book from the library. Write a test class, which creates an object of type library, adds several books to it. Implement a test functionality, which finds all books authored by Stephen King and deletes them. Finally, display information for each of the remaining books.Create a class “Student” with data members such as roll number, name and branch. Create another class “Exam” for storing marks of three subjects. Derive a new class “Result” from “Student” and “Exam” class with data members such as total and average. Display the values of all the data members. Develop a C++ program to model the above relationships. Include comments for the code. Also, can you include screenshots of the code and the output as well Test cases Private – Input 1000 ABC CSE 90 80 70 Output 240 80 Public – Input 2000 DEF IT 25 30 35 Output 90 30Create a class IntArray.
