{
init_expression ;
while ( cond_exression ) {
loop_statement
iteration_expression ;

}

Die init_expression wird vor der Ausführung der Schleife ausgeführt. Die cond_expression wird auf den Wert zu beurteilen, umwandelbar in bool. Es wird vor jeder Iteration der Schleife ausgewertet. Die Schleife wird nur, wenn ihr Wert true ist. Die loop_statement auf jeder Iteration ausgeführt, wonach iteration_expression ausgeführt wird .
Original:
The init_expression is executed before the execution of the loop. The cond_expression shall evaluate to value, convertible to bool. It is evaluated before each iteration of the loop. The loop continues only if its value is true. The loop_statement is executed on each iteration, after which iteration_expression is executed.
