Loop Problem

[compsci]

While the status is at C or L, I want the user to input the participation and print it to the screen. I can't get my online_adjustParticipation function to run either. Everytime I run it, it loops the same amount of times as the first loop.

while(status == 'C'){

Hi. I think this is the part of your code you are referring to. You are asking for the student to enter the participation and you are recording that as the status. Then you are passing adjust as a parameter when adjust has been given no value. I expect you wanted to assign the input to adjust and not to status. Another thing to think about is, assuming my guess above is correct, if the user enters 7.5 you have no return value that applies to this function and, finally, this while loop is infinite if my guess is correct.

I am trying to make functions of the following:
• adjustParticip returns the adjustment factor reflecting the student’s class participation. It is passed the 0-10 evaluation of the student’s class participation as well as a character ‘C’ or ‘L’. For ‘C’, it delegates to on_campus_adjustParticipation, for ‘L’, it delegates to online_ adjustParticipation,.
• score2letter is passed a numerical course score and returns the corresponding letter grade. (This does not delegate its work since this conversion is the same for on-campus and online students.)

I have tried to do the adjustparticip function but it is not running right. It functon continues to loop.. For an on-campus student, the factor for adjusting the course score is 1 if his/her participation score is 4 or less, it is 1.04 if his/her participation score is from 5 to 7, and it is 1.08 if this score is 8 or more. For an online student, the factor is 1 if his/her participation score is 3 or less, 1.02 if this score is from 4 to 6, 1.05 if this score is from 7 to 9, and 1.08 if this score is 10.

I dont know how to start on the score2letter function. Th e function is suppose to compute the letter grade from the adjusted course score. A score of 90 or above (because of the adjustment, the score might be over 100) is an A, 80 up to (but not including) 90 is a B, 70 up to (but not including) 80 is a C, 60 up to (but not including) 70 is a D, and anything below a 60 is an F.

This is what I have so far:

OK. We can continue with this and get it to work or just nip it in the bud. This depends on you responding to my posts and the two of us working together on the problem, which I am more than happy to do if I get the idea that you are playing along.

So the first step is for you to read my last post and respond only to what I posted. Do not add any other information or code. One step at a time :)

Okay I'm ready
