Use of null statement in C

Question

What are typical uses of null statement

;

in C ?

I know that it is basically used to skip expression where it is expected

Answer 1

The only uses I can think of are:

1- At the end of a loop, where the operations are already encoded within the loop statements. e.g. while(a[i--]);

2- At the end of a label, where no operation is needed to be done. e.g. Label: ;
