我可以使用break退出多个嵌套for循环吗？ [英] Can I use break to exit multiple nested for loops?

问题描述

使用 break 函数退出多个嵌套 for 循环是否合适？如果是这样，你会怎么做呢？

Is it proper to use the break function to exit several nested for loops? If so, how would you go about doing this? Can you also control how many loops the break exits?

推荐答案

AFAIK，C ++不支持命名循环，比如Java和其他语言。您可以使用goto，或创建一个您使用的标记值。在每个循环结束时检查标志值。如果设置为true，则可以跳出该迭代。

AFAIK, C++ doesn't support naming loops, like Java and other languages do. You can use a goto, or create a flag value that you use. At the end of each loop check the flag value. If it is set to true, then you can break out of that iteration.
