How to create a min heap of fixed size using std::priority_queue? I can define a min heap as: I have a stream of integers. The min heap's size is a fixed value k. It seems that priority_queue can not do this. If you want to use std::priority_queue, it's trivial to l......

I am just wondering if there is a smarter more elegant way to do this by using a different container. Ideally I would stick to some container from the c++ standard library. EDIT: someone suggested a priority queue (answer got deleted). In this case, would I create a heap of pairs and...

The current implementation of tbb::concurrent_priority_queue internally uses a heap, so that is indeed what you should be seeing right now when inserting elements sequentially in FIFO order, but how would that be helpful to your presumably concurrent application? It's not a documented con...
