Hi,
I defined the following operator to stream optional<char>'s:
std::ostream & operator<< (std::ostream & os, boost::optional<char> const & op) { if (op) os << *op; else os << '_'; return os; }
Now, when I use:
boost::optional<char> a ('a'); std::cout << a;
'a' is printed like I expected. However, when I use:
std::ostream_iterator<boost::optional<char> > oi (std::cout); *oi = a;
'1' is printed and my operator is apparently ignored (I expected another 'a'). Is this a gcc (3.2.3) issue or a boost issue?
Neither. Your operator<< definition should be in namespace boost.
