// A program to illustrate the use of formatted output

//-------------------------------------------------------------------------

// We need iostream for the basic i/o and cmath for the sin we use near 
// the end.

#include <cmath>
using namespace std;

int main() {
  const int A = 5;
  const double B = 3.4568;
  double C;

  // The output strings explain what is going on:

  cout << "Output using fixed precision, 2 decimal places:\n";
  cout.setf( ios::fixed, ios::floatfield );
  cout.precision( 2 );
  cout << "B=" << B << endl;
  cout << "Output using width=10, left justified:\n";
  cout.setf( ios::left );
  cout.width( 10 );
  cout << "B=" << B << endl;
  cout << "Output using width=10, right justified:\n";
  cout.setf( ios::right );
  cout.width( 10 );
  cout << "B=" << B << endl;
  cout << "Repeat the formatting if you want the same thing again:\n";
  C = sin( B );
  cout.setf( ios::right );
  cout.width( 10 );
  cout << "C=" << C << endl;
