Beispiel
Diesen Code ausführen
#include <iostream> #include <experimental/string_view> int main() { std::string str = " trim me"; std::experimental::string_view v = str; v.remove_prefix(std::min(v.find_first_not_of(" "), v.size())); std::cout << "String: '" << str << "'\n" << "View : '" << v << "'\n"; }
Ausgabe:
String: ' trim me' View : 'trim me'
