However, with the do while loop, the loop code
will occur at least once regardless of the expression, but will only repeat if the evaluated expression
returns true .
class WhileLoops
{
public static function main()
{
var myInt : Int = 0;
// will print to screen ten times
while ( myInt < 10 )
trace( ???displayed ??? + ( ++myInt ) + ??? times??? );
// will skip as myInt == 10
while ( myInt < 10 )
trace( ???displayed ??? + ( ++myInt ) + ??? times??? );

81
// will display once as myInt will be bigger than 0
// though this is not evaluated until after one iteration
do
trace( ???displayed ??? + ( 10 - --myInt ) + ??? times??? )
while ( myInt < 0 );
}
}
As you can see in the example, the line executed in the do while loop does not end with a semicolon ( ; ).
Like if statements, a do while loop doesn ??™ t require a single line of code to end with a semicolon. In fact,
the compiler is insistent that one does not exist. You will still need to apply them to blocks of code,
however.
