[18:15:43]  <Chris>	 Norrin: it's, like all C declarations, "declaration follows use".

[18:16:14]  <Chris>	 So consider char (*x)[42]; You can then reason that *x is a char[42]. And (*x)[3] is a char.

[18:16:46]  <Chris>	 Norrin: and in the case of char *x[42]; you can say that x[3] is a char * and *x[3] is a char.

so [] has precedence over *.  hence why the () are required depending on intention. 

[18:14:32]  <Chris>	 Norrin: char *(*a)[42]; is a pointer to array of 42 char pointers.
