Goto and Empty Statements

goto label;

label: statement

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()) ;.
