Multidimensional arrays in Boo
When declaring a variable or a field as a multidimensional array, use this syntax:
foo as (int, 3) //declare a 3 dimensional array of integers.
When creating a brand spanking new multidimensional array, use this syntax:
foo = matrix(int, 2, 3, 4) //That creates an empty 3 dimensional array. //1st dimension will have 2 items, 2nd has 3, 3rd has 4
Set and retrieve data from the array:
foo[0,0,1] = 100 print foo[0,0,1]
This shows looping over the array to set or get values:
n = 1 for i in range(len(foo,0)): //# of items in 1st dimension for j in range(len(foo,1)): //2nd dimension for k in range(len(foo,2)): //3rd dimension foo[i,j,k] = n ++n //Print the values out in a table format: columns = len(foo, foo.Rank - 1) line = [] for item in foo: line.Add(item.ToString("00")) if len(line) >= columns: print join(line) line.Clear()
The whole code together produces this output:
100 01 02 03 04 05 06 07 08 09 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24
