Well it looks for all the world like your temp isn't pointing anywhere. A crude fix might be to make temp an array of char, rather than just a pointer to char. Better, use std::string for all your strings.

> I write my thesis in Artificial Intelligent fields. Perhaps create an AI system which can auto-respond to all the "please think for me" posts we seem to get on this forum.

In a loop which runs 12 times, you want [code=c++] cin >> temps[0][col]; // this is max cin >> temps[1][col]; // this is min [/code]

Sure, figuring out how to use code tags would be high on your list. You were a lot closer than most people manage, but you still didn't make it.

You're not going to believe this, but there's this new fangled invention called [URL="http://clusty.com/search?query=approximate+square+root+algorithm&sourceid=Mozilla-search"]"Da Interweb"[/URL] which has useful tools like "Search Engines". Take a trip to [URL="http://www.catb.org/~esr/faqs/smart-questions.html#before"]here[/URL] as well, then read the rest of the ASQ (for that is what it is).

Maybe upgrade to a compiler which matches your OS, rather than cling to the backward compatibility ? Lets begin with which option you chose? Or perhaps add some error detection to the initgraph() call. [url]http://www.cs.colorado.edu/~main/cs1300/doc/bgi/initgraph.html[/url]

> Also is this code correct? I am getting strange errors... Whilst saying that they're "strange" errors is a step up on "I'm getting errors", it really doesn't help us that much to figure out what's going on. Be specific, post actual error messages and actual observations.

The short answer is you can't. The language itself is portable, therefore it works hard to avoid any explicit knowledge of the OS on which it is running. Take TurboC (an often used, but misplaced example), and your OS is XP. Is your OS a) DOS b) The Virtual DOS …

> but I don't know the order. Then you'll have to read the documentation to find out. You can't just look at 2 bytes and decide which order they're supposed to be in. When you have found out, it will be one of [icode]result = ( x1 << 8 ) …

So what's the problem? Have you read the relevant documentation to learn about the .cap file format? Are you able to open and read the file, and retrieve a packet? Are you able to decode the header of that packet to determine it's purpose?

How about the other "incentive" of working out which people are worth helping? If two posters have started 100 threads (say), where one of them has marked nearly all of them as "solved", and the other hasn't even bothered, then I'd like to know.

So why didn't you put the comments in when you wrote it? Also, how come you missed all the hints to use [code][/code] tags when posting code.

> t = num / 10; If num is 1234, then t is 123 This is WAY beyond the end of your array.

1. main returns an int, not void. 2. None of your strings have a \0 at the end, so things like printf with %s, and atol are going to be disappointed. 3. a = atol(&string1[cnt]); I rather suspect you want just the digit value, in which case it would be …

Gee, yet another massive post from someone too dim to figure out how to use code tags despite the numerous places where they get explained!. Good luck with that, I'm sure people will be only too glad to wade through several hundred lines of unformatted code for a fossil compiler …
