Do Statement

Syntax: do Statement while ( Expression );

Semantics: The statement is executed first and then the expression is evaluated which must be of boolean type. As long the expression remains true, the statement is executed repeatedly.

Note: The while statement evaluates the condition first and then, as long it remains true, executes the statement repeatedly. In case of the do statement the condition is not evaluated before the first iteration is performed.

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