setiosflags

manipulator function

<iomanip>

smanip setiosflags ( ios_base::fmtflags mask );

Set format flags

Sets the format flags specified by parameter mask.

Behaves as if a call to the stream's member ios_base::setf with mask as argument was made.

This manipulator is declared in header <iomanip>, along with the other parameterized manipulators: resetiosflags, setbase, setfill, setprecision and setw. This header file declares the implementation-specific smanip type, plus any additional operator overload function needed to allow these manipulators to be inserted and extracted to/from streams with their parameters.

Parameters

mask: Mask representing the flags to be set.
This is an object of type ios_base::fmtflags which can take any combination of its possible values (see ios_base::fmtflags).

Return Value

Unspecified. This function should only be used as a stream manipulator (see example).

Example

1 2 3 4 5 6 7 8 9 10

// setiosflags example
#include <iostream>
#include <iomanip>
using namespace std;
int main () {
  cout << hex << setiosflags (ios_base::showbase | ios_base::uppercase);
  cout << 100 << endl;
  return 0;
}

This code uses setiosflags manipulator to activate both the showbase and uppercase flags, with the same effect as if inserting manipulators showbase and uppercase.
