Write a program to perform student record manage for class IST311. It contains two parts: student record class and main program. It should get the student information from the user and set up student record class array with proper size. The program will perform sorting student record by last name then first name, compute each student’s final grade, then print out the student information list, then search highest student final grade and use ToString() in student class to print out this student’s information. Part I: Student class (Already done in Assignment 2) Student class definitions: It should contain first name, last name, 5 labs grade, 3 exams grade, final grade. Its member functions are default constructor, 2 copy constructors, display student’s information and override ToString(), which only display class type, last name, first name, and final grade. (Note: labs grade and exam grade are array with 8 elements) Student class implementation: Your implementation: All base set get information for student’s information’s. Default constructor: set student class variables to default value. String variables set to "None", double variable set to 0, and all elements in the array set to 0. 2 Copy constructors: set student class variables in student information by different number of pass in parameter list
