Complete the following:

Solution

  1. NOTE: You need to start indenting your programs properly. Points will be taken off for not indenting this homework appropriately
  2. Reminder to look at CMSC104 Indentation Standards
  3. Create a copy of hw09.c called hw10.c
  4. Be careful you don't lose/overwrite your hw09.c
  5. Note that one directory up from your home directory is a directory called "backup" that stores a nightly backup of your entire home directory. You can look there for files that get corrupted/lost.
  6. You are going to implement the same program as hw09, but you will use arrays to store the set of homeworks, classworks, and quizzes.
  7. Modify the program to have an array of integers to store each of the classwork grades, an array for homework grades, and an array for quiz grades.
  8. Create the arrays as the maximum size of assignments for our class (16 classworks, 12 homeworks, and 5 quizzes)
  9. If the user tries to say there were more than that number of assignments, print an error and ask again.
  10. Keep track of all of the grades, and then after the user inputs them all, calculate the averages and the final GPA.
  11. After printing out the GPA, you should also print out a list showing the individual user classwork, homework, and quiz grades that were entered.
  12. After printing out the list of all values, also print the highest and lowest values for each set of items (classwork, homework, quizzes)
  13. Example run: 

    How many homeworks have been completed: 24
The maximum number of homeworks is 12, try again
How many homeworks have been completed: 3
Home many classworks have been completed: 4
Home many quizzes have been completed: 2
Enter 1 if the final has been completed: 0
Enter homework 1 grade: 90
Enter homework 2 grade: 95
Enter homework 3 grade: 95
Enter classwork 1 grade: 20
Enter classwork 2 grade: 100
Enter classwork 3 grade: 100
Enter classwork 4 grade: 75
Enter quiz 1 grade: 90
Enter quiz 2 grade: 90
Your total GPA is: 89.1
Your homework scores are: 90, 95, 95
Highest homework score is: 95
Lowest homework score is: 90
Your classwork scores are: 20, 100, 100, 75
Highest classwork score is: 100
Lowest classwork score is: 20
Your quiz scores are: 90, 90
Highest quiz score is: 90
Lowest quiz score is: 90

  14. Create a script of you running your program twice.
  15. Once you are done, use submit to submit two files, hw10.c and typescript
