Goto and Empty Statements
The next statement executed after the
goto will be the one
following the label. It must appear in the same function as the
goto, but may be before or after.
This null statement is occasionally used in looping statements, where
all the "work" of the loop is done by the expressions. For
example, a loop that calls a function
foo() repeatedly until it
returns zero can be written as
while (foo()) ;.
