使用
continue意味着您在while中编写的条件不充分。您应该在
while循环中使用if，或者将条件添加到while循环中。The use of
continuewould mean that you have insufficient conditions written in yourwhile.You should instead use
ifinside yourwhileloop, or add the condition into thewhileloop.在循环体内使用 goto、break、 continue、 throw 或 return 也可能会产生不良效果。这是循环控制和循环体紧密交织的另一个示例。还像以前一样写1、2、3吗？你确定吗？
您可能会认为建议您不要在循环体内使用 return 语句过于热心了。我真的是这个意思吗？是的，我愿意。返回某些内容的函数应该通过函数末尾的单个 return 语句来完成。以下是一些实际原因：

Using goto, break, continue, throw, or return inside the loop body can all have the un-desired effect as well. Here's another example where the loop control and the loop body are tightly interwoven. Does it write 1, 2, and 3 as before? Are you sure?
You might be thinking that advising you not to use return statements inside loop bodies is over zealous. Do I really mean that? Yes I do. Functions that return something should do so via a single return statement at the very end of the function. Here are some practical reasons why:

Continue的效果在某种程度上类似于转到循环开头的goto。因此，它使您的代码更难以理解 - 就像goto一样。The effect of
continueis somehow comparable to agototo the begin of the loop. It therefore makes your code more difficult to understand - likegotos.
