• J C Calvarese (12/35) Jan 30 2004 You might try:
• Phill (4/39) Jan 30 2004 Ok thanks! I like exotic :o))

Can somebody please explain why this code:

int[20][2] whatever;
 whatever[19][0] = 2;

gives this error:

test.d(6): array index [19] is outside array bounds [0 .. 2]

and  this code gives the same error:

int[2][20] whatever;
 whatever[0][19] = 2;

test.d(6): array index [19] is outside array bounds [0 .. 2]

Im still using v0.77 so was it a bug in this ver or am
I doing this wrong?

You might try:

int[20][2] whatever;
  whatever[0][19] = 2;

or

int whatever[2][20];
  whatever[0][19] = 2;


It's like this on purpose.  I think it's to faciliate porting exotic 
code from C, but I don't recall any more details.

So that the syntax is logical.

int[20][2] is an array of two int[20]s, not of 20 int[2]s.

Declarations then read from right to left, rather than C-style middle to 
right and then to left, or hopping about as you were thinking of it.
