I though D should have syntax similarities with C, but recently I've
found that array indexing in D is different. Suppose we have a code:
import std.stdio;
void main ()
{
wstring[6][2] strings;
strings[2][0] = "test";
}
It fails to compile because of error:
"./main.d(6): Error: array index 2 is out of bounds strings[0 .. 2]"
Why? There should be 6 rows and 2 columns, but it seems that it's the
opposite. Am I misunderstood something or is it a bug?
Yes, opposite.
C's array declaration mimics the way arrays are used in code: first row,
then column. In D, array declarations are always "type followed by
square brackets";
int[N] arr;
Array of arrays follow the same consistent definition: first type, then
the square brackets. So if we need an array of 6 elements where the type
of elements is int[2], then we follow that description (space added for
emphasis):
int[2] [6] arr;
