how where arrays stored again?

[Piotr Sawuk]

I'm trying to re-compile some old ltris version, and got
ISO C++ forbids casting to an array type `int[12][400]'.
caused by the line

((int[BOWL_W+2][BOWL_PIX_H+BLOCKSIZE])bowl)[(int)cur_y + by*BLOCKSIZE + b]

so I hope that in order to compile this I need to multiply i
by 400 and add the other stuff, or was it the other way around?
sorry, I'm not experienced with this old-code-repairing.
is int[a] an array of int[a] arrays or one of int arrays?
or is there an option for g++ to compile without any ISO-checking?

I'd probably use a typedef:

typedef int bowl_array[BOWL_W+2][BOWL_PIX_H+BLOCKSIZE];

and then do this:

((bowl_array)bowl)[(int)cur_y + by*BLOCKSIZE + b]

If it doesn't work, try a reference to that array:

((bowl_array &)bowl)[(int)cur_y + by*BLOCKSIZE + b]

[snip]

int[a] is a two-dimensional array with a rows and b columns. I'm
guessing this is old C code, which tends to be more lax on conversions.
Why don't you try a C compiler (e.g., gcc) rather than g++?

hmmm, strangely the debugger is telling me that

&((int[BOWL_W+2][BOWL_PIX_H+BLOCKSIZE])bowl)[0][0]

is a lot smaller than (int*)bowl, thereby making my whole idea of
emulating above construct in an iso-compilant c++-compiler useless.
basically it seems that in the situation with an error-message like

error: ISO C++ forbids casting to an array type `int[12][400]'

one is forced to completely re-write the definition and the logic
behind the involved types. it seems iso-c++ is in some cases a whole
different programming-language than old c++ or c, in that a complete
re-write is quite inevitable...
