You're right not to be sure. You cannot provide an initializer for array types. According to 5.3.4/14, the only types which can have initializers are class, arithmetic, enumeration, pointer or pointer to member types. The special rules pertaining to using a string literal to initialize an array don't apply here, either. -- James Kanze home: kanze@gabi-soft.fr +33 (0)1 39 55 85 62 office: kanze@vx.cit.alcatel.fr +33 (0)1 69 63 14 54 GABI Software, Sarl., 22 rue Jacques-Lemercier, F-78000 Versailles France -- Conseils en informatique industrielle -- --- [ comp.std.c++ is moderated.
