[Dev-C++] ios header file

[Danny A. <tam...@ms...>]

Could someone tell me if ios header file is suppose to exist in Dev C++? =
 When I try to compile the code below I get the error that ios does not e=
xist.

#include <iostream>
#include <iso646>
using namespace std;
int main(void)
{
    cout << "Default True, False \n"
         << true << " " << false << endl;
         =20
    cout.setf(ios::boolalpha);
    cout << "\nwith ios::boolalpha:\n"
         << true << " " << false << endl;
         =20
    cout << "\n140 in hex\n";
    cout.setf(ios::hex, ios::basefield);
    cout.setf(ios::showbase);
    cout << 140 << endl;
    =20
    float f[2] =3D {1.0f, 775.374f};
    =20
    cout << "\nDefault numeric formula\n"
         << f[0] << endl
         << f[1] << endl;
         =20
    cout.setf(ios::showpos);
    cout << "\nand with shopos\n"
         << f[0] << endl
         << f[1] << endl;
         =20
    //indicates that cout should always use 6 digit precision
    cout.setf(ios::fixed);
    cout << "\nand with a precision of 6\n"
         << f[0] << endl
         << f[1] << endl;
  //system pause
  char end;
  cin >> end;
  return 0;
}
