DarkBASIC Discussion / A question about Arrays = Zero? (It's stupid so brace yourselves...)

This is going to sound pretty stupid, but I need to know.

If I create an Array:
DIM ArrayName(#,#,#,#,#)

Will all the coordinates start with a value of 0 by default?

The answer to this could save me a lot of time...
Or doom me to repetitive typing for the next few hours.

Ack! I didn't see the 'Newcomers Corner' section of the forum.
I should have posted this there.

!!!

When I said coordinates I don't mean the # in the array I mean
ArrayName(1,2,1,1,2) = ?
Where '?' is the variable I require information on...
(Oops... I'll try to avoid not clarifying in future...)

Everything starts at 0. Repetative typing? You never need to do anything repetative in programming, thats what a loop is for.

Thanks for the help. (That saves me a nice chunk of time!)

Unfortunatly using a loop won't auto-build the database I'm constructing.
(I've got to convert all my design notes into data *sigh* time consuming, but interesting in it's own way...)

Example:
DIM ArrayName(2,2)
ArrayName(0,0) = 0
ArrayName(1,0) = 2
ArrayName(2,0) = 2

ArrayName(0,1) = 18
ArrayName(1,1) = 2
ArrayName(2,1) = 1

ArrayName(0,2) = 17
ArrayName(1,2) = 2
ArrayName(2,2) = 18

I needed a blank array for the program to add values to while it was running, but I still have a lot of data-entry to go for the rest of it.

personally if making an editor to enter the data is not an option i would put those numbers in a text file and read them in in a loop

if u don't want to do that u can use the data command and a for/next loop

Wandering Swordsman, you don't ever have to use element 0 of an array if you don't want to. I usually just start at position 1. When they're created, they're created with one more element than you specify.

dim a(5) actually creates 6 positions, 0-5. Just start at one and you'll reduce your logic errors. If I use 0 then I use it as a control element. It just depends on what I'm doing.


Come see the WIP!

@Hobgoblin Lord:
Been working on one for a while...
I'm looking into storing the data in separate files and reading them into the program.

@Slayer93:
Data command is now on my list of things to learn.

@Phaelax:
Thanks for the code snippet.
*Reads it over carefully...*
I see:
By using 'i' & 'j' in the for/next loop and as array coordinates you can transfer the data into the array coordinates as the loops variable changes.

@Cash Curtis II:
Thanks for the info.


*Salutes*
Thanks to everyone who posted to this thread, sorry it took so long for me to post a response.
(This thread has served it's purpose. Now let it slowly fade back into the dark recesses of the DB forum...)
