Title
Body
I have a C++ struct and a method: struct Account { unsigned int id; string username; ... }; Account GetAccountById(unsigned int id) const { } I can return an Account struct if the account exists, but what to do if there's no account? I thought of having: An "is valid" flag on the struct (so an empty one can be returned, with that set to false) An additional "is valid" pointer (const string &id, int *is_ok) that's set if the output is valid Returning an Account* instead, and returning either a pointer to a struct, or NULL if it doesn't exist? Is there a best way of doing this?
