2D arrays

[MysticVegeta]

I know what 2D arrays are but i have a question on hwo to use them, for example if i have a 2D array, how do i get them to match each other for example :

1st -> 1st
1st -> 2nd
1st -> 3rd

2nd -> 1st
2nd -> 2nd
2nd -> 3rd

3rd -> 1st
3rd -> 2nd
3rd -> 3rd

Match each other, hard to understand?? =S

wat does -> mean?

I think it means "=".

do u get the question though?
umm
do u wanna replace all the values in the array that has the index with the same values?
ummm

code:

var nums : array 1 .. 3 of int for i : 1 .. 3      nums (i) := 1 end for

Now they all equal 1. Is that what you wanted? Not sure what is meant by 2D array (Never heard of them).

2D arrays r arrays wich r stored in an array...i know someone (probably Cervantes) wrote a tutorial on it...all i remember was wat 2D arrays r and that it was a good tutorial

ex)

code:

var test:array 1..5,1..5 of int for i:1..5    for a:1..5       test(i,a):=i*a    end for end for

that right there is a 2d array. so each array of 1..5 has another array of 1..5, so test(1,1) would = 1 , test(3,5) would = 15. hm.. maybe like a graph may work to explain best

code:

test(1,*)=  test(1,1)             test(1,2)             test(1,3)             test(1,4)             test(1,5)             test(2,*)=  test(2,1)             test(2,2)             test(2,3)             test(2,4)             test(3,5)             test(3,*)=  test(3,1)             test(3,2)             test(3,3)             test(3,4)             test(3,5)             test(4,*)=  test(4,1)             test(4,2)             test(4,3)             test(4,4)             test(4,5)             test(5,*)=  test(5,1)             test(5,2)             test(5,3)             test(5,4)             test(5,5)

kinda like that lol

thats 2D arryas in a nutshell!!!

btw: ur not limited to just 2 dimensions, u can go all the way to watever if u like but that would be confusing and....(i digress)......

okay now i have a question, is it possible to have a string variable inside an integer variable, or vice versa? like for example a high score, i would want to store the persons username and then theyre score, i could put them both into a string array but then i wouldent be able to sort them unless i used the strint function, any ideas?

i sugest using records

code:

var player:array 1..2 of         record             name:string             score:int         end record

[Flikerator]

Its easy to suggest records when you don't explain how to use them

Yah after I asked what 2D arrays where I read a tutorial on them...Thanks though

Records are VERY useful with arrays/flexible arrays.

srry i think kinda wierd and in my own way so i dont think to explain things at first

code:

var player:array 1..2 of %making an array of 1..2 of the following         record %starts the record lol             name:string %gives the variable player(x) a sub variable             score:int %adds another subvariable         end record %end the record, could have more variable if wanted

as an example you would do:
player(1).name:="Bob"
player(1).score:=13

that way 'Bob' would have a score of '13' sotred under the same variable, you can make a type by using records (pretty sure in tutorial) and u can even use records in records if you wanted to. just an easy way to store sub variable uynder one name to keep track of them

Yea its something like that but if the first array is 2, 4, 5, 6, 3 and the second array is 3, 2, 5, 6, 1

then
if
2 matches 3 then do blah
2 matches 2 then do blah
2 matches 5 then do blah
2 matches 6 then do blah
2 matches 1 then do blah

4 matches 3 then do blah
4 matches 2 then do blah
4 matches 5 then do blah
4 matches 6 then do blah
4 matches 1 then do blah

5 matches 3 then do blah
5 matches 2 then do blah
5 matches 5 then do blah
5 matches 6 then do blah
5 matches 1 then do blah

try nested for loops

code:

for i:1..upper(array1)     for a:1..upper(array2)         if array1(i)=array2(a) then             %do stuff         end if     end for end for

cool thanks
