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';*/
}
}
