HELP! calculating student's average

Hey guys, I think we were a bit too rough on Jason. Yes, I agree, the post is about homework. However, he's not asking us to do the homework, he's just asking for a little help to fix it up. He also posted a pretty nice program so we can see that he's well ahead on doing the homework.
Give the kid a break!

Re: HELP! calculating student's average
Actually, you program looks good, but has a lot of problems, especially with the nested WHILE/WENDs.jasonkidd007 wrote:......
The program is almost done, i just need professional help to perfect it.
One problem with WHILE/WENDs is that there is no EXIT WHILE. So try to use DO/LOOPs instead where you can get out with an EXIT DO.
Another alternative to your nested WHILE/WENDs is SELECT CASE. Have you used that yet?
By the way, you said you can't use IF, but you used two of them.
PRINT "Wow a mark of"; average; "Holy Cow!"
The reason this message prints in an infinite loop is because it takes the exit out of the WHILE/WEND when counter is >4, it later hits the WEND at the bottom of the program, loops back up to "WHILE numcourses > 0" and starts the counter at 15 all over again.
The last 2 WHILE/WENDs, where you set counter=1 and then loop WHILE counter=1, puts the program into an infinite loop also. What you want here is to get out (finish). Just do a SYSTEM or an END.
WHILE 90 < average <= 100
This is really strange syntax to me, and I've been programming Basic for over 30 years. I compiled your code and got no error, but I don't understand what this statement means.
Good luck.

Guys, there's a difference between someone asking for someone to do their entire homework assignment for them, and someone asking for help on a homework assignment. As you can tell by the almost-finished program that jasonkidd007 wrote, he put in a valiant effort to finish the assignment, and just needed a little bit of help to get his code to work. This kind of post is precisely the reason why this forum exists.
Moneo: thanks for helping him out.

i agree thanks for helping him moneo...moneo wrote:Pete, thanks for posting your position on homework. I totally agree with you. That's why I went ahead and tried to help him.
Regards..... Moneo
he did make an effort... he just didnt make a blank
question asking for help or a weak 3-4 line attempt
at something....
What a surprise...moneo wrote:Yeah, but like many others, he hasn't come back to acknowledge the help given nor anything.

But yeah, I was harsher than needed, because I forgot to check his postcount. This guy actually has one, and so I should just have left the topic without posting at all. My bad.
I have left this dump.
Not to worry. You're kind of post helps to clear the air, and keeps them on their toes.Z!re wrote:What a surprise...moneo wrote:Yeah, but like many others, he hasn't come back to acknowledge the help given nor anything.

Re: HELP! calculating student's average
Hmm... It doesn't seem like this would work. Usually $$$ like this will require an AND statement. WHILE 90<average AND average <=100 is usually what it would be. The only use I could think of for this is detecting if the grade went over 100 somehow or became too low (below 90). I'll have to look into this!moneo wrote:WHILE 90 < average <= 100

Or he visited here before Sun Oct 01, 2006 1:11 am and is now too scaredmoneo wrote:Yeah, but like many others, he hasn't come back to acknowledge the help given nor anything.
Code: Select all
WHILE 90 < average <= 100 
Never seen anything like that. I hope jasonkidd007 comes back and tells what he means (or tried to mean) with that one.
Well no if's hope it works ok. You could also use SELECT CASE but I assumed you wanted only DO LOOP / WHILE WEND.
