An expression-statement evaluates a given expression. The value computed by the expression, if any, is discarded.

Not all expressions are permitted as statements. In particular, expressions such as
1 that merely compute a value (which will be discarded), are not permitted as statements.
Execution of an expression-statement evaluates the contained expression and then transfers control to the end point of the expression-statement. The end point of an expression-statement is reachable if that expression-statement is reachable.
