array tutorials?

[cheawick]

Can anyone point out some good tutorials on initializing and using arrays and matrices?
Thanks!

[Valmont]

Just about every tutorial on the net or in a book covers arrrays. Is there something in particular you want to know?

[cheawick]

Thanks for the reply!
I'm trying to figure out how to write an array (or matrice) that will hold three different values and can be rewritten (or perhaps better to say updated).
It's part of a "game" (if you could call such a non-interactive thing such). If you want to see what code I have so far I'll email it to you, I'd wager it is too large to post here.
Thanks!

[cheawick]

Oops! I forgot to mention that there are six different instances(?)of the three values running at the same time.

[Valmont]

It's ok. As long as you realize that pointer handling and array handling goes hand in hand.

[cheawick]

Umm. Pointer handling? I've heard of pointers, but never encounter their use as of until now. Would you be so kind as to elighten me on this subject?
Cheawick...

[Valmont]

Well, not "hand in hand" perse. Although they are related.

[cheawick]

Well, here is what I have so far as far as code, or at least what I have tested in compiles and runs.

EGAD!!! Cut and paste works terrible here! Or is there another way to post code?

Thanks!
Cheawick.

#include<dos.h> //for the clear screen function

//values back to the calling functions

cout<<"This is a non-interactive simple game named SIMPLEGA\n";
cout<<"When the enter key is pressed, six units called Cores will be generated.\n";
cout<<"\nThe following are the three type classes that make up a Core.\n";

//display body, target, and attack including the 3 possible values of each
//example: body= life 20, life 25, life 30 >not needing this exact format<
//example: target= random core, core with high life, core with low life
//example: attack= damage 10, damage 12, damage 15

//step 2: determine damage to each core

//step 3: determine any dead cores

/*NOTE TO SELF!!! MAY NEED TO CHANGE THE STATIC NUMBER IN THE FOR STATEMENT

Never mind about the appearance issue, I see it looks better than on the posting board.

Cheawick.

[redhead]

just write [ code] [/ code] around what you want kept with the required indentation.

[cheawick]

I'm assuming you mean [ code] at the beginning and [/ code] at the end? Yes?

Yes. Try it. Just edit your post and insert them.
Just a tip: learn to place comments above the line of code. Not to the right of it.

Besides that, you are using a pure (16 bit) dos program, calling in86. These days Win32 api calls are used. I have VC versions so I cannot check out your code, since later VC versions don't generate pure DOS programs.
But if you like to move on with pure dos programs then here is a some reading for you: 256 color programming

Good luck!

Sorry SDE, but I don't understand the "--split--" and link below it. The link brings me back to my last post here. Did I miss something?

[Valmont]

He is new sde .

Anyway, what problems do you have with DevCPP? Did you download it from my site?
Check out THIS THREAD and see how it goes.

You also asked a question about the full potential of C++ and platform independent programming. First of all, ansi C++ does not know about platforms (like Windows XP), so that problem is solved straight away. Certainly when studying as a novice, you won't be bothered by platforms much (console programs).

But first check out the link I gave you (above) and try to move on from there.
