Grades - c program

write a program which will read 3 exams grades for a class of students, calculate and display the average and letter grade for each student, and then display some statistics for the class as a whole. For example: Suppose that a class had 8 students with these exam scores: 90 92 81 60 70 75 93 100 95 40 30 55 80 70 78 55 60 73 90 91 92 94 93 92 Each line contains 3 exam scores for a student. For the input data shown above, your program should produce output in the following format: student exam 1 exam 2 exam 3 average grade 1 90 92 81 87.67 B 2 60 70 75 68.33 D 3 93 100 95 96.00 A 4 40 30 55 41.67 E 5 80 70 78 76.00 C 6 55 60 73 62.67 D 7 90 91 92 91.00 A 8 94 93 92 93.00 A ------ class average -> 77.04 Student averages ranged from 41.67 to 96.00 grade distribution: 3 A *** 1 B * 1 C * 2 D ** 1 E * Your program should be designed to handle any number of students greater than 0. Each student will have 3 integer exam scores. For simplicity, you may assume that the input data will always contain valid integer numbers in the range [0,100] and that there will be no more than 70 students who have the same grade. Letter grades should be assigned based on the following thresholds: A [90,100]; B [80,90); C [70,80); D [60,70); E [0,60). I do not need to a file to test the program, but you may want to create one of your own to test it.

## Deliverables

1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Complete ownership and distribution copyrights to all work purchased. ADDITIONAL INFORMATION: In designing your program output, follow the form of the examples shown above. Columns of numbers should be neatly aligned under the column headings and should be right justified. All averages should be displayed with 2 digits after the decimal pt. In the grade distribution one asterisk should be displayed for each student earning that grade. IMPORTANT: All data should be read using scanf. DO NOT USE fscanf or any other "file" reading function. SUGGESTIONS: your program should contain a loop controlled by a scanf. Within the loop, the program should calculate the student's average, determine his letter grade, do other needed processing, and display the line for that student. After the loop, the program should display the line above the class average, then display the class average and then display the grade distribution output. You might want to use a for loop to display the asterisks.

## Platform

Windows XP

## Deadline information

Use very basic c. I don't need anything fancy. In fact I prefer that the program is written as stated under suggestion. Thanks
