If the ANSI Strict option is off in the C/C++ Language Panel, the compiler allows arrays of no length as the last item in a structure. Listing 3.5 shows an example. Arrays may be defined with a zero as the index value or with no index value between brackets.

struct listOfLongs {
	long listCount;
	long list[0]; // OK if ANSI Strict is off, [] is OK, too.
}
