1. Assume that the weights sum to 100.
2. Assume that the number of items in each category is positive.
3. The number of Final Exams will always be 1.
4. There will be no more than 10 grades in any category.
5. All scores are based on a maximum of 100 points.
6. All scores in a given category are equally weighted.

1. All data for a given category will be on a single line.
2. No input line will be long than 100 characters.
3. Since you don't know how many grades will be on a line, you should use look_ahead to help you determine if there are any more values on the line. The program lookaheaddemo.adb (prettified) show look_ahead in use.

1. Your program is to have no prompts.
2. Students are to be output in descending order of letter grade and in the same order as they were input within a given letter grade (ie use a stable sort).
3. Output all numeric values with one decimal point.
4. Use a 10 point scale: 90.0 and above is a grade of "A", less than 60 is a grade of "F", and so on.

1. Your program should be called grades.adb
2. Your main routine is to have only three statements (ie it will consist of three procedure calls: input, calculate, output).
• Each procedure is to have exactly one parameter.
3. You should make good use procedures, functions, records, and enumerated types when designing your program.
4. Make sure that you test your program on rucs2.
5. Make sure that you do NOT use any GLOBAL VARIABLES in your program! All communication with procedures and functions must be via parameters and return values!

Style: In coming up with your Ada solution to the following problem, please follow my style guide. In particular, please note the use of consistent indentation, named constants, and descriptive constant and variable names. Please remember that the first thing in any program file should be a comment that gives a brief overview of what the file contains (and should do). Also remember to keep your lines less than 80 characters long. Not only does this mean that printouts won't run off the side of the page, but it also makes your programs look neater on an 80 column wide xterm window (a popular size). If you are unsure of an element of programming style, please ask, as I would be more than happy to show you what I want.

Submission: Use the submit command to turn your program in for grading. You may submit as many times as you like, but only the last submission is kept. In particular, be aware that since only the last submission is kept, if the last one is late, then your assignment is late and will thus receive a late penalty. Also remember that you must be on rucs2 for submit to work. To submit your work for grading do the following:
