合并两个 std::queue [英] Merge two std::queue

问题描述

stl 中是否有任何函数可以连接两个 std::queue 对象?

Is there any function in stl that joins two std::queue objects?

推荐答案

std::queue 适配器不支持迭代，因此您实际上必须推出自己的方法来执行此操作.但鉴于您需要此功能，您可能应该考虑使用不同的容器.如果您需要随机访问，可能是 std::deque.如果您只需要像队列一样的前/后访问，请考虑 std::list，它可以在恒定时间内 spliced 在一起.

The std::queue adapter doesn't support iteration so you'd actually have to roll your own method to do this. But given that you need this functionality, you should probably consider a different container. If you need random access, the probably std::deque. If you only need front/back access like a queue consider std::list which can be spliced together in constant time.
