Pascal Programming- Arrays?

Hi! I'm taking a computer science class in which we use Pascal to write all of our programs. IRight now we're working with arrays, and I'm completely lost.





The program we're supposed to write is:


Write a program that computes grades for a class of up to 50 students. The program reads in a score in the range 0 . . 100 for each student and then outputs the grades, identifying each student by number (first is 1, second is 2, etc) Any student who receivces 10 points below the average receives an F. Any student who receives above that and at most 10 points above the average receives a C. Any student who receives a score above that receives an A. There are no D's or B's. To use your program for a larger class, you should not need to change anything except the constant declaration section.





I know I need


const maxstudents = 50





And I'm guessing I would need to use parallel arrays?





I really just need help getting it started. Thanks!

Pascal Programming- Arrays?
you can add this in your const :


valueBelowAvg = 10;


valueAboveAvg = 10;


so when their ask you to change the rules to get a grade, you just change their constant value.





you can use this for array :


var arrType : array [1..maxStudents] of integer;





and for grading, make a function with if.. then.. else.. and compare it with your constant value.
Reply:hi sam, actually despite of the programming language, i think you should concentrate on the program logic. You can start with defining a class of students. I cant answer much but im a computer science student also in Malaysia. You can contact my handphone number. 016-2417247. Take care
Reply:Right. You use array to store the scores.





type


arraytype = array [1..50] of integer;








Another tip is use "case" command to shorten your program when assigning A, C or F
