How do I sort and stable_sort elements with std::multiset?

In C++, a std::multiset is a type of associative container that allows for the storage of elements with the same value while maintaining order. Unlike std::set, a std::multiset allows for duplicates. To sort a std::multiset, you can rely on its internal ordering, but if you need a sorted copy or special sorting criteria, you may utilize algorithms like std::sort with other containers.

Example of Using std::multiset

#include #include int main() { std::multiset ms = {2, 3, 1, 4, 1, 5, 2}; // Displaying the multiset std::cout << "Multiset elements (sorted): "; for (const auto& elem : ms) { std::cout << elem << " "; } std::cout << std::endl; // Sorting is inherent as multiset keeps elements in sorted order return 0; }
