By that same argument, there's no reason for double to be treated the same as int, since it's not an int. In many ways double is more similar to complex than it is to int. complex<> is defined as an implementation-defined class, but that's not the only way it could have been done. In Fortran and in C9X, it's a fundamental type. In C9x, complex will obey the same initialization rules as the other built-in types. Even as a class type, the default constructor for complex<> could have been defined to leave it's members uninitialized, just like the built-in types. > See -- C compitibility. Could you be more specific? I didn't find any reference to complex in the "C compatibility" Annex. [ comp.std.c++ is moderated. To submit articles, try just posting with ] [ your news-reader.
