with QBasic.
"Assume that your money is invested in an account that draws interest compounded annually. That is, at the end of each year the amount invested (principle) is multiplied by the interest rate, and that interest amount is added to the principle. Write a program, using a FOR.. NEXT LOOP, that will get the amount invested, the interest rate, and number of years from the keyboard (INPUT statements). It should then produce a printout showing how much money will be on hand at the end of EACH year."
So far, this is what I have:
INPUT "Enter amount to invest: ", moneyinvested
INPUT "Enter the interest rate: ", interestrate
INPUT "Enter number of years to invest: ", years
FOR X = years to 1 STEP -1
totalmoney = (moneyinvested * interestrate) + moneyinvested
NEXT X
Any help would be appreciated! :)

Uhh.. I don't think anyone here *uses* or *knows* QBasic.... :P
-
I know it a little though I haven't used it in ages. Also, I have a friend who just took a programming class online that for some reason programmed in QBASIC.
In the loop add "PRINT totalmoney" I think that is what is need. I'll check when I get home and have the program, I think QBASIC is on my computer somewhere. QBASIC is a language that I haven't used in a long time.
-
I know QBASIC.
Basically you want a /PRINT "You have ", totalmoney/ in there
-
Ah, Why would you atempt to learn QBasic anyways?

Probably because he took a class where it was taught. I can't think of any other reason...

Exactly.
@rabbit/Miamiandy: The program is far from finished than by just adding a simple PRINT statement. Re-read the instructions in my first post. :P
-
You also need to another to plug total money back into the equation for every subsequent year following the first one.

Rabbit was around back in the days of QBASIC, I think. In fact, I remember back when Windows 95 was bleeding edge, Windows 3.1 was commonplace, and Visual Basic 3 was the thing to do.
-
The first language I learned was QBASIC and at the time I could use it quite well. Although, this was 8 or so years ago. I was in 3rd or 4th grade at the time I think.

Arn't you like 15? So..you were programming at the age of like 8?

17 years old. I definitely was doing QBASIC in 4th and 5th. Nothing else till 7th though.

Not you, I quoted Joe for a reason :P

Oops, sorry.

I first learned to program QBASIC and Batch on Windows 3.11/MSDOS and (pwn) for OS/2 :P

I always feel that when people ask for help on homework it forces the forum members into a moral dilemma. The people who assist never know for sure whether the teacher allows it or whether the person asking for help is honest.
Anyways, hints...
That's not how compound interest works. It semantically resembles it but is conceptually stranded. If you have any questions about compound interest, post in the math forum ^_^.
-
mm, and another hint
Your code doesn't make sense. You're reassigning a variable to a constant times a constant plus a constant each iteration of the for-loop.

Uhh.. I don't think anyone here *uses* or *knows* QBasic.... :P
How does that prevent people from helping?
Woops, triple posted =\ Mods feel free to merge these...

Now how's he supposed to learn anything? >:(

Yes, that was a hindrance to his learning. And although one may plausibly argue that such a transgression causes insignificant disturbance to the educational system, it is more a matter of morality. Just like downloading music illegally.
*braces himself for angry responses*

Go fuck the RIAA. We don't care about your stance on downloading music.
Illegally downloading music has nothing to do with posting code for a homework assignment. You just want attention.

My favorite artists, Sigur Ros and Explosions in the Sky, distribute their music freely on their sites. Ergo my taste of music is superior.

So does Heathen. I'm pretty sure you could find places that allow you to download their composures of Vivaldi, Bach, Mozart and Beethoven legally, therefore, you suck at analyzing your taste in music. ;)

Feel free to delete it, I originally was just going to do it but not post it, but then I changed my mind.

A lot of my indie bands post their music on the Internet for free downloads.

Arn't you like 15? So..you were programming at the age of like 8?
I'm sixteen. I started programming basic AppleScript back in like.. third grade. So yeah, I was programming at the age of eight. From there I stepped up to some Commodore / Apple II BASIC, which I've completely forgotten. Eventually I moved at the beginning of a summer vacation and found myself in my room, programming, 24/7, becoming the God of VB.

Joe, there are a lot of things I would call you. God of VB is not on that list.

Compared to some people though, I'm rather good, no? :P

I'm pretty good at roller blading, but I don't think I'm the god of it.

Though I tend to agree with you to an exent, from what I've seen, I think you've been brainwashed by "the educational system" into taking these things a bit too seriously. In the big picture, does it really matter that much? (Hint: this is a rhetorical question, and the obvious answer is no).

Some people like retarded 5 year olds, or people who can read?

Depends if you're Nigerian or not.

That's like saying a penguin is good at swimming compared to other birds. :P

You picked a bad example, because you know that out out of one iago's know that penguins are the God's of everything.
