(scope?) question

class DateTime
{
public:
typedef enum Format
{
DDMMYY = 0,
DDMMMYY ,
DDMMMYYYY ,
MMDDYY ,
IS08601
};

std::string ToString(const Format fmt= DateTime::ISO8601, const
std::string& sep="-" ) const ;
};


Error: error C2065: 'ISO8601' : undeclared identifier


Why can't the compiler recognizer the enum?

I tried typedefing the enum (although I read its not required in C++ -
same as struct declarations don't need a 'typedef' anymore)

0 != O (means 'Zero' != "Oh")

S.

Stefan already answered that (and I'll admit that I wouldn't
have seen it either).

The typedef'ing not only isn't necessary, it's somewhat harmful.
I'm not even sure it's legal in your case, since the typedef
doesn't apply to anything. Don't do it, except when writing
compatible headers, which must also be compiled by a C compiler.
