Hej!
Kan det passe at følgende ikke kan compileres?
string s="tekst";
cout<<s;
Jeg får følgende fejl:
error C2679: binary '<<' : no operator defined which takes a right-hand
operand of type 'class std::basic_string<char,struct
std::char_traits<char>,class std::allocator<char> >' (or there is no
acceptable conversion
Hvis jeg skriver cout<<"etEllerAndet"; virker det fint.
Hvordan får man ellers en string-variabel udskrevet?
På forhånd tak!

std::cout << std::string( "foo" );
_skal_ fungere (dersom <iostream> og <string> er #include'ert)

Tak for hurtigt svar!
Efter jeg har included <string> virker det fint.
