Iterate values of a map using range-based for loop

Recently I started using range-based for loop. I had a problem where I needed to sort a map by value and then assign value to vector/array. Can I do that with this loop?

for (auto& it : M){
    // value to vector
}

This question would be the same if I had a vector of pairs, could I just check for second, if it is larger then some other element or number? All this using range-based for loop.

>Solution :

From C++20, you can use views::values to get at the values of a std::map, or a vector<pair> for that matter:

for (auto v : m | std::views::values)  // m is some map
  // ...

demo

You can similarly get at the keys with views::keys.
