init_expression执行循环之前执行。 cond_expression应评估值，转换为bool。它是在每次循环迭代计算。该循环继续，仅当它的值是true。 loop_statement在每次迭代时被执行，之后执行iteration_expression.
可以用作终止声明. 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.
