std::resetiosflags(3) C++ Standard Libary std::resetiosflags(3) NAME std::resetiosflags - std::resetiosflags Synopsis Defined in header <iomanip> /*unspecified*/ resetiosflags( std::ios_base::fmtflags mask ); When used in an expression out << resetiosflags(mask) or in >> rese- tiosflags(mask), clears all format flags of the stream out or in as specified by the mask. Parameters mask - bitmask of the flags to clear Return value Returns an object of unspecified type such that if str is the name of a stream of type std::basic_ostream<CharT, Traits> or std::basic_istream<CharT, Traits>, then the expression str << resetiosflags(mask) or str >> resetios- flags(mask) behaves as if the following code was executed: str.setf(std::ios_base::fmtflags(0), mask); Example // Run this code #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'; } Output: 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 See also setf sets specific format flag (public member function of std::ios_base) setiosflags sets the specified ios_base flags (function) http://cppreference.com 2022.07.31 std::resetiosflags(3)
