Standard C++ doesn't know about screens or graphics or pixels. You need to say more about your setup (OS, Compiler etc) Start by practising simple stuff, like say just drawing a line.

A real pre-emptive OS would need a clock interrupt (from the outside world) to function. This would be capable of interrupting "while(1);" and give control back to the OS to decide on something else to do.

What a fantastic first post! Code tags and nicely indented code - top notch stuff. > The output always reads 0 0 0. scanf("%s") uses all white space as a delimiter, so no spaces etc will ever appear in your string. Try [ICODE]fgets( s, sizeof(s), stdin );[/ICODE] instead.

We're missing the rest of the code. Random "memory corruption" bugs generally mean the problem could be anywhere else in the code EXCEPT the part you're staring at and the handful of lines you've posted. A small and complete self-contained example which shows the same problem would allow us to …

Perhaps you should explain why you don't have a pointer of the correct type to begin with. [ICODE]pVBRes = new anotherType[someSize];[/ICODE] If you do this elsewhere, what is to stop you performing the wrong cast?

Well which OS/Compiler/GUI system are you using? None of this is standard C++.

In C++, you should be using [ICODE]new [/ICODE]and [ICODE]delete[/ICODE], or [ICODE]new[][/ICODE] and [ICODE]delete[][/ICODE]

I know you yanks like spelling English words differently, but seriously, it's "Throne", not thrown (which is the past participle of throw). "Tabloids" and "rumours" - yep, seems about right.

Use a debugger, and it will point you at the line of code which is dereferencing a NULL pointer.

Well speaking of vague.... Your post makes very little sense to begin with.

So use one of the several XML parsers which are available at the end of any search engine. [url]http://expat.sourceforge.net/[/url]

There are plenty of examples on the board for that kind of conversion.

You're using a 16-bit assembler, and those registers are only accessible from 32-bit programs.

And we're supposed to guess(believe) that you declared [B]AND [/B]allocated [B]ALL [/B]your buffers correctly?

I must say that I'm really liking the new prefix the mods are applying to threads wrested from the clutches of the zombies :)

1. Your indentation sucks - no wonder you can't find anything wrong with it, it's way too hard to trace your way through it. This is some improvement, but it could still be better.

The prototype needs to be [ICODE]void deal (user&, user&, card[]);[/ICODE] if you want to modify the details of the user and dealer.

Use a debugger, and set up a data access breakpoint on the address in question. It will break whenever that location is read or written.

Your compiler will have read the entire function, and worked out in advance just how much space each local variable would need (and the total space). At code generation time, the right amount of stack space can be reserved.

I think the universe would have been much better off if you'd just deleted the post Walt. Most everyone here would be glad to see someone so lazy to "flame out" of the course they're on. The OP should get their "flame on" down at the local burger joint instead. …

I think they've screwed up the compiler installation by editing stdio.h at some point in an attempt to solve a problem. Now, every project is broken. Re-install the compiler and SDK.
