Question: You are required to write a program to use parrel arrays to determine grades of students from their given marks using the instructions given below: i. Create a loop to read the students' IDs and their corresponding total marks in the course from the students.txt input file. *While reading store the ID numbers and Marks in two seperate parrel arrays. One array should contain IDs and another array should contain marks i.e string id and int marks *Hint: use a while loop structure to read data from a file. ii. Print out ID numbers and Marks of all the students on the screen after reading the data from the input file is done. iii. iii. The function: char determine_grade(int total_mark) defines how to determine the grade for each student according to the criteria in the following table: Marks Grade 80-100 A 65-79 B 50-64 C 0-49 D â€¢ The function receives as parameter the mark of a student and returns the grade character corresponding to the mark range. The function is already defined. â€¢ Determine the grade of each student by calling the determine_grade() 2 function within a loop that reads the mark of each student from the marks array. The grade returned is stored in the char grades array for each student. iv. Define the function: void print_students_records(string sid, char sgrades, int size) to print studentsâ€™ IDs and their corresponding grades. The function receives the id, and grades arrays and size (size is the number of records to print). Call this function after the grades have been determined. v. Define the function: int total_failed_students(int smarks, int size) to determine the number of students who have failed the course. The function receives the marks array and size and returns the number of students failed. Call this function after printing student records.
