You are given a partially completed program hw04q1.c. You should follow the instructions given in the program to complete the functions so that the program executes as instructed. You will need to implement three functions. The program declares a struct studentRecord with elements for student's name, student's major, school year of student, student ID. You will be completing a program that creates a list of students (array of structures). It is a menu-driven program where the user is given the following options: a) Add a new student to the list. When adding a new student to the list, the user is prompted for student's name, student's major, school year of student and student ID. The student should be added at the end of the list. If the student already exists in the list, then you should not add to the list. The school year is enum type. b) Display the list of students. This should display each students details one after the other. c) Sort the list of students alphabetically by student name. The sorting should happen within the list. You should not create a new list (array of structs) of students having sorted students. There is save() already implemented to write the students list to a file Student_List.txt. save() is executed when the user quits the program. You need to implement load() which is called at the start of the program. This function will read the saved file and fill in the array of structures. You need to read the file in the same order and manner that it is saved in save(). Expected output of each function:

Notice that since this is the first execution of the program, load() gave the message "Student_List.txt not found". This file is created at the end of the program by save().
