Re: [Dev-C++] Number of elements of a multidimensional

[Carlos d. M. <cg...@wo...>]

The sizeof applied to a array will give you the size of a pointer, never
the size of the array.
Say char *array; or char array[];
Then sizeof(array) =3D 4. (at least in my intelIII x86, with win2k 4 is
the size for any kind of pointer).

The only solution is to have some special value for the end of the
array. Which for strings is '\0', and you can try to set another
depending on which kind of data you're working with and which range of
values you can find, so you can then choose on of the values which are
out of the range to set as that special value. So you can reach for it
and you can then now, with the approppriate functions you can write the
total size of the array and the size of each row of the multidimensional
array.
