This function isn't doing anything: [CODE] double diameter(double diam) { double d ; while (d = 2 * radius ) return d ; }[/CODE] You're passing in the radius, not the diameter, so your function argument should be named to reflect this. Also, you're not using the value that you're …

Wait.....what? What do you mean? You want to do what in functions? Call a separate function to read in the input and a function to perform the math? A separate function for each arithmetic operation? You only want to have variable declarations and function calls in your main()?

Did you [URL="http://support.microsoft.com/kb/315265"]chkdsk[/URL] it?

Needing vista to use those functions is BS. The functions without Ex at the end are windows 3.1 (and above) compatible and the ones with Ex at the end are Win32 compatible. Why are you using the Win32 function to set the value, but the Windows 3.1 function to open …

I wouldn't be so sure that it's duster gunk. The only thing spraying it upside-down should really get on it is the propellant (C02 ?), which should just freeze it and then evaporate. My concern would be that one of the electrolytic capacitors went south and leaked it's goo everywhere …

Hi all. Bear with me, I promise this will be hardware related in a minute... I'm working on a project for which I need to generate some FSK. I'm doing so by using a sin(...) function to calculate the values along the wave for N periods of frequency A and …

First, join ACM. If you're currently a student then you can qualify for the student membership rate, which is really cheap. You'll get loads of books and online courses to help you learn all sorts of programming topics. In just about any field anymore you can probably get a decent …

Check the input immediately after reading it in and break out of the while loop right there if it's -1. ETA: Or, rather, return immediately...I wasn't paying attention to where you do the calculations. ETA2: You'll also have to make a flag to tell if you've read in any good …

Good eye, dkalita. In other words, OP, you need to either only display the values (save to an int and output that int) or, if you want to keep all the squared and cubed values, you'll need to store them in square_array and cube_array.

You need to move your if/else inside of your while loop. Unless the first input is -1, you're just going to keep doing this over and over and over: [CODE]Number[i] = Input; Count++;[/CODE] because Input will never change from the first input and it won't stop executing the while loop …

Edit: oops, never mind. Is there a way to delete my own post?

Please use code tags when posting code. That's really hard to read.

You want something like the Linksys WCG200-RM, NETGEAR DGN2000, or NETGEAR DG834G. They are combination cable/DSL modems plus routers. I don't think the one you posted will cut it.

What? If I understand you correctly, you have to capture "count" when you set the min and max values.

Looks like prince is a string and you're comparing it to a character? Use double quotes rather than single quotes. That was keeping it from compiling; was that all you wanted help with, or did you need help with the logic also?

If you can read them in OK, then you can just do the math on them to get the values. Do you understand how different number bases work? Each of those 32 bit strings is just representative of a power of two i.e. 2^x where x is the place of …
