Keep the order of unordered_map as we insert a new key

Question

I inserted the elements to the unordered_map with this code:

    myMap.insert(std::make_pair(\"A\", 10));
    myMap.insert(std::make_pair(\"B\", 11         


        

Answer 1

No, it is not possible.

Usage of std::unordered_map doesn't give you any guarantee on element order.

If you want to keep elements sorted by map keys (as seems from your example) you should use std::map.

If you need to keep list of ordered pairs you can use std::vector>.
