Expression statements have the form
expression-statement:
expression ;
The expression is a discarded-value expression.
Allside effects from an expression statement are completed before the next statement is executed.
An expression statement with the expression missing is called a null statement.

Most statements are expression statements — usually assignments or function calls.
A null statement is useful to supply a null body to an iteration statement such as a whilestatement ([stmt.while]).
