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.

[Note 1:

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]).
