  // types supported by StreamFormatter.
  //
  const char* s = "Hello World";
  bool b = true;
  int i = 1234;
  unsigned int ui = 32767;
  double d = 1.2345;

  //
  // Declare a formatter for the standard output stream.
  //
  StreamFormatter stf(cout);

  //
  // The format string prints a boolean, an integer, two
  // unsigned integers, a floating point value, and a string.
  //
  const char* format = "bool    b = %b;\n"
                       "int     i = %d;\n"
                       "uint   ui = %u;\n"
