Field width

• requires header <iomanip>

• manipulator std::setw( n ) determines minimum output width n.

• shorter than the field width output is padded with fill characters.

• For example,

      #include <iostream>
      #include <iomanip>
      using namespace std;
      int main () {
        cout << setw( 40 ) << "Hello";
        return 0;
      }
      /*
      Output:
                                         Hello
      */
