26. Alignment of Numeric Fields

• Adjusting numeric fields:

  
      #include <iostream>
      #include <iomanip>
      using namespace std;
      int main() {
        int x = -1234;
        cout << setw( 10 ) << internal << x << '\n';
        cout << setw( 10 ) << left     << x << '\n';
        cout << setw( 10 ) << right    << x << '\n';
        return 0;
      }
      /*
      Output:
      -     1234
      -1234
         -1234
      */
