C - Gradebook program

Need two gradebook programs written in "C". One will grade an individual classroom of 12 students, the other must grade 3 separate classes of with 12 students each. Program will get its data from keyboard input. Must use an array of structs. 1st function will load FIRSTNAME, LASTNAME and exam grades for 6 exams. 2nd function will calculate the average grade for each student as well as the class average score. 3rd function will sort the class average by grade in descending order. A=91-100, B=81-90, C=71-80, D=61-70, and <60=F. Each students' grade must be converted to a letter grade. Exam scores also need to be written to a file on a disk. No global variables can be used. Must use pass by value (no pointers). Need in a hurry!!! ## Deliverables Complete source code of all programming work done ## Deadline information Must be completed by 7/14/2001.
