Design and develop a program that accepts test score values from the Console window until the user enters the value -1. The value -1 is called a sentinal value, which is used to tell the loop to exit when the number of values is entered. After the user enters the sentinal value (-1), compute the average of values based on the running total and the number of values entered. Display all three values-in the console window using a user-friendly message. For example, test scores of 100, 95, 90, and 90, should produce the results shown in figure 3-19. This is what it should look like when you input it.


Enter a score: 100
Enter a score: 95
Enter a score: 80
Enter a score: 90
Enter a score: -1

The total of the values is: 365
The number of scores is: 4
The average is: 91.25

Press the ENTER key to continue._

I can only input two scores right now, and then the program screws up.

My variables are
Dim intScore As Integer
Dim intCount As Integer
Dim intAverage As Integer

Can someone please solve this, you would be doing me a HUGE favor, Would anyone like to try it? It's supposed to take 10 minutes, but I haven't been able to do it for some reason...

I'm not sure whether you're supposed to assign an array or not. My whole class was messed up because of the blizzard and now it's catch up.

intCount = intScore + 1

Then again, this is the first time I have used variables that = 0, and they never even taught us how to do that in class.

By the way, can you not do intCount++ or intCount += 1 in VB.NET?
If not, I'll stick with C#, thank you

---

Oh you big programming baby.

Once again thanks for the help, I appreciated it a lot. I finally saw that I was making a moutain out of a mole hill.

So far they've only taught us to declare variables like:
Dim intCount As Integer
or
Dim decAverage As Average

but yeah, no intCount = 0 or intTotal = 0. Maybe they didn't have time, but that's still no excuse. They also said not to worry about arrays yet, although I've done a little bit of them, how are they?

If you don't mind me asking do you program for fun, for a job?

I like to program and when I don't use it, I forget syntax of the languages. It gets frustrating when you know what you want to do but can't remember the proper syntax of the language.

---

LOL ... that's the worst part of programming. It's like trying to learn english, spanish, french, italian and german ... then switching to one for a couple of years, and then moving to another and trying to remember it again.

Right now I program almost exclusivly in VB, but occasionaly use Perl here and there. When I have to do something in Perl, I'm almost ALWAYS forgetting to put a semi-colon at the end of my statements and can never figure out why they're erroring out.

Of course I usually find my missing semi-colons in the VB code I'm working on concurrently.

It's bad enough that if I don't use a function for a couple months, I need to research it on the internet again to remember the correct syntax.

I use mostly, .asp here at work now for alot of things, this way anyone can access them from a browser to do what they need. Got a couple of VB programs here as well, but I forgot more than I remember, and can't update them now

I've ridden in that boat quite often and will do so again.

It can get really hard - that's why I have tons of manuals and books at work.

I use java, C, perl, Unix shell script, Oracle PL/SQL all the time and it's so easy to confuse the syntax among all the different languages!

c++ .Net and c++ are 2 different things...c++.net relies on .net, now you can configure visual Studio to do c++ nativly, but you would need the windows sdk along with it which can be downloaded

THANK YOU, I just took my CIT final exam and the test was to incorporate a loop into a program. Needless to say I passed with flying colors, and it took me about 2 mintues for the thing to work.

Thanks for helping me out!
