Strings (Output Formatting)

• To format output we use the manipulators accessed by including #include<iomanip>.
• The setw() manipulator sets the field width of the next output.
• The setprecision() manipulator is used to set the precision of the next floating point number.
• By using the fixed manipulator, you ensure that trailing zeroes are displayed.
• The sequence of commands

  cout << fixed << setprecision(2);
  cout << setw(8) << pennies << " "
    << setw(8) << pennies * 0.01 << "\n";
  cout << setw(8) << nickles<< " "
    << setw(8) << nickles * 0.05<< "\n";
  cout << setw(8) << dimes<< " "
    << setw(8) << dimes * 0.1 << "\n";
  cout << setw(8) << quarters<< " "
    << setw(8) << quarters * 0.25 << "\n";
