Given a binary file containing the scores of 50 students in a class on Systems Programming course, compute the following statistics. Design the program such that the file should be specified as command line argument. 1. Maximum score 2. Min score 3. Average score. 4. Standard deviation 5. Number of students who got an “A Grade (90 <= score <= 100) 6. Number of students who got a “B” grade (80 <= score <90) 7. Number of students who got a “C” grade (70 <= score <80) 8. Number of students who got a “D” grade (60 <= score <70) 9. Number of students failed (score < 60) Write a separate function in a separate file for each of the above and a header file and ‘scores.c’ for main function. Menu: 1: for Max score, 2: for Min score, 3: ---- 9: for Number of students failed. 10. for Exit, 0: for continue. The data file scores.dat is attached to the assignment. You may download the file and copy into Cygwin with the following command: cp “C:\Users\loginname\Downloads\scores.dat” scores.dat OR you can use the attached C-program to generate your own scores.dat file 1. Statement of the problem (as given above) 2. Program Design (function hierarchy diagram) and program code (weight 0.2) 3. Compilation results (copy from unix window and paste it to MSWORD file) 4. Show the results (copy from unix window and paste it to MSWORD file) 5. If the program has bugs, show you used debugger and show how you fixed the program (Get a screen shot and paste it to MSWORD file) 6. Conclusions prog scores.c #include #include #include int main() { FILE *fp; int i; fp = fopen("scores.dat","wb"); int scr[50]; for (i=0; i < 50; i++) scr[i] = 50+random()%100; fwrite(scr,50, sizeof(int),fp); return 0; } create your own scores.dat file in C language please

Given a binary file containing the scores of 50 students in a class on Systems Programming course, compute the following statistics. Design the program such that the file should be specified as command line argument.
1. Maximum score
2. Min score
3. Average score.
4. Standard deviation
5. Number of students who got an “A Grade (90 <= score <= 100)
6. Number of students who got a “B” grade (80 <= score <90)
7. Number of students who got a “C” grade (70 <= score <80)
8. Number of students who got a “D” grade (60 <= score <70)
9. Number of students failed (score < 60)
Write a separate function in a separate file for each of the above and a header file and ‘scores.c’ for main function.
Menu:
1: for Max score, 2: for Min score, 3: ---- 9: for Number of students failed.
10. for Exit, 0: for continue.
The data file scores.dat is attached to the assignment. You may download the file and copy into Cygwin with the following command:
cp “C:\Users\loginname\Downloads\scores.dat” scores.dat
OR you can use the attached C-program to generate your own scores.dat file
1. Statement of the problem (as given above)
2. Program Design (function hierarchy diagram) and program code (weight 0.2)
3. Compilation results (copy from unix window and paste it to MSWORD file)
4. Show the results (copy from unix window and paste it to MSWORD file)
5. If the program has bugs, show you used debugger and show how you fixed the program
(Get a screen shot and paste it to MSWORD file)
6. Conclusions
prog scores.c
#include <stdio.h> #include <stdlib.h> #include <math.h> int main() { FILE *fp; int i; fp = fopen("scores.dat","wb"); int scr[50]; for (i=0; i < 50; i++) scr[i] = 50+random()%100; fwrite(scr,50, sizeof(int),fp); return 0; }
create your own scores.dat file
in C language please
