Merge two std::queue

Question

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

Answer 1

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.
