It's used where the language requires a statement.

In, say, C, you would use empty braces:

      while (process_next_item()) {
          /* Do nothing. */
      }

If I want to express nothing in C, I put nothing and it works fine.

#include <stdio.h>

int main(int argc, char * argv[])
{
   if(1 == 1)
     ;

No. You put ";", that's not nothing.
