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
       */
