Hi, I can help a little bit but I don't guarantee it to be right also :D
1. Yes, only the first dimension can be omitted in the type
specification. But as I remember, array is allocated at compile time,
therefore in the definition all size must be specified.
int c[][3] = {1,2,3,4,5,6}; // the first dimension is implicitly set
to 2 (2x3 = 6);
int c[][3]; // this would probably cause error
int c[2][3]; // this will do
To have a dynamic multidimensional array use malloc with pointer
arithmetic.
2. To check the legality of the code, why not compile it yourself. And
for constructor definition, a C text book would serve well :D
3. There is a type of cast called reinterpret case which can
deconstantize a const.
