could some one run this and tell me what i did wrong i really need to learn this

I'm doing that now.

First problem, I don't know C, though I'm faking it. :D

Second problem, you've got numerous errors in your code that you should have caught on your own. Silly stuff, really.

Third, I don't know C. (Did I mention that?)

i am new bie and this program has been giving me a headache

for the last week

i cant debug it

i was told if i tried u guys would be glad to help me

so i tried and now i am just totally lost

This I, at least, got to compile and run:

Code:

Now, I don't have the slightest idea about how 'happy' I am, but, never mind that part. :)

Your prompts work fine. Up until the 'table' executes, you're okay, as well.

(C programmers, feel free to jump in here, would ya?!?)

Anyway, Belfour, let me digest this a little more. In the meantime, take what I've posted and start doing some debugging of your own. Pay attention to the 'scanf' stuff I've commented out because they hang the program. Also, your functions must re-declare your variables. They're out of scope!

pay attention to comments. I really don't know C, but that should help debug the errors.

Belfour,

Can we talk? Let's, also, think in terms of using descriptive variable names? 'a' for 'principal' doesn't get it! (I'm pulling your leg here, but not by much!) :)

-Skipper

I leave the formatting of the data, for display purposes, to you (you probably know better than I do...right?). I've played with it, but that's all I've done is "play". (A little success, but...)

Your 'print_amortize' function is giving some God-awful value in the first column. Double-check both the type and value here. The fact that the value goes negative after 'x' number of iterations suggests that you're exceeding the limits of the 'type' that's being printed. (A "flag", as it were.) Again, I'm abyssmally weak in C so I can't say what's going on, or why.

Hopefully, one of the other folks with a stronger background in C will offer some advice. :)
