When the program below is compiled and executed, it produces the
following output:

(many lines omitted)
e = 8.98847e+307, f = 4.49423e+307
e = Inf, f = 8.98847e+307
e = Inf, f = Inf

When the two lines containing cout are uncommented and the printf
line is commented, the following output is produced:

(many lines omitted)
e is 8.98847e+307
f is 4.49423e+30

and the program hangs.  A similar problem occurs when double is
changed to float.

#include <stream.h>

main()
{
  double e;
  double f;

  e = 2;
  f = 1;

  /* make larger */
  while (e > f)
    {
      e *= 2;
      f *= 2;
      printf("e = %g, f = %g\n", e, f);
/*      cout << "e is " << e << '\n';
      cout << "f is " << f << '\n';*/
    }
}
