Upper

Do we have a built-in function to convert a string declared as

string A="Ab";

to uppercase

[Danny]

What's a built-in function? A standard (extern) function or a member function of std::string?
There's no member function of std::string that does that but you can use toupper to convert each character individually.
This omission is about to be fixed soon, though. There has been a lot of demand for such a member function.
