>Description:
Once you use the line setiosflags(ios::right) then
subsequent calls to setiosflags(ios::left) do not work.
It get stuck on right only. The following code demonstrates
this:
#include <cstdlib>
#include <iomanip>
#include <iostream>
using namespace std;
//using std::ostream;
int main(int argc, char *argv[]) {
cout << setiosflags(ios::left) << setw(15) << setfill('.');
cout << "Converged";
cout << "YES" << endl;
cout << setiosflags(ios::right) << setfill('*');
cout << endl;
cout << setiosflags(ios::left) << setw(15) << setfill('.');
cout << "Converged";
cout << "YES" << endl;
return 0;
}
If I compile with:
g++ (GCC) 3.2.3 20030309 (Debian prerelease)
the output is:
mythdrannor 18:47 > a.out
Converged......YES
......ConvergedYES
If I run with g++ version 2.95 the correct output is given:
mythdrannor 18:47 > a.out
Converged......YES
Converged......YES
I am running debian linux with the 3.2 compilers currently
in the unstable branch.
>How-To-Repeat:
See attached file. Compile and run with 2.95 to see the
correct output. g++-3.2 give a reversed output for the
final print statement.
