Syntax: while ( Expression ) Statement

Semantics: The expression must be of type boolean. If it evaluates to false, the given statement is skipped, Otherwise it is executed and afterwards the expression is evaluated again. If it is still true, the statement is executed again. This is continued until the expression evaluates to false.

Following layout conforms to our coding standard:
while ( Expression ) {
    Statement₁
    Statement₂
    ...
}
