Defined in header <iomanip>
/*unspecified*/ resetiosflags( std::ios_base::fmt_flags mask );

When used in an expression out << resetiosflags(mask) or in >> resetiosflags(mask), clears all format flags of the stream out or in as specified by the mask.

Contents

Parameters

mask - bitmask of the flags to clear

Return value

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:

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
