It does exactly what I expect: it prints 0.  If you expect anything
else, you don't understand how C works.  When you do this:

	f = 55 / 77;

The compiler evaluates the 55/77 part first - the division of two
*integers*.  Integer division returns an integer result (0).  *Then*
it's converted to a floating point number (0.0) in order to store it.

If you want the compiler to divide floating point numbers, you have to
tell it to do that:

	f = 55.0 / 77.0;
