Michael et. al. -- G++ 1.35.0 on a uvax3. Consider the following program: -------------------------------------------------- #include <stream.h> struct foo { public: foo(); private: int i; }; foo::foo() { cout << "Hello.\n"; } void main() { foo f(7); } -------------------------------------------------- This should give an error message, because there is no "foo" constructor that takes an integer argument. Instead if gives no argument. Even more insidious, it does not call the default constructor -- when run, the above program prints nothing. Thanks. Ad astra. Dave
