[modifier] Retourne la valeur
Retourne un objet de type non précisé de sorte que si
str est le nom d'un flux de sortie de type std::basic_ostream<CharT, Traits> ou std::basic_istream<CharT, Traits>, alors l'expression str << resetiosflags(mask) ou str >> resetiosflags(mask) se comporte comme si le code suivant est exécuté:Original:
Returns an object of unspecified type such that if
str is the name of an output stream of type std::basic_ostream<CharT, Traits> or std::basic_istream<CharT, Traits>, then the expression str << resetiosflags(mask) or str >> resetiosflags(mask) behaves as if the following code was executed:The text has been machine-translated via Google Translate.

[modifier] Exemple
#include <sstream> #include <iostream> #include <iomanip> int main() { std::istringstream in("10 010 10 010 10 010"); int n1, n2; in >> std::oct >> n1 >> n2; std::cout << "Parsing \"10 010\" with std::oct gives: " << n1 << ' ' << n2 << '\n'; in >> std::dec >> n1 >> n2; std::cout << "Parsing \"10 010\" with std::dec gives: " << n1 << ' ' << n2 << '\n'; in >> std::resetiosflags(std::ios_base::basefield) >> n1 >> n2; std::cout << "Parsing \"10 010\" with autodetect gives: " << n1 << ' ' << n2 << '\n'; }
Résultat :
Parsing "10 010" with std::oct gives: 8 8 Parsing "10 010" with std::dec gives: 10 10 Parsing "10 010" with autodetect gives: 10 8
