Question

Write a program to complete the following tasks. Record all results to a data file called "GradeSheet.dat".(1) Read the grade sheet from attached data file, "Assignment4.dat". Print the original grade sheet.

(3) Write a module to sort array GRADE[] and print the sorted grade sheet.

(4) Write a module to sort array NAME[] and print the sorted grade sheet.

(5) Write a module to sort array ID[] and print the sorted grade sheet.

(6) Write a module to print the student's id, name, and grade for student with highest grade and with lowest grade, respectively.

(7) Write a module to determine mean of the grades.
