C Order Map . 🎀🧸 In C++, however, this is not so: std::map is a sorted associative container; std::unordered_map is a hash-table based associative container introduced in C++11 This means when iterating the key-value pairs of a std::map the order will always be known but that insertion or lookup (search) is slower than std::unordered_map.

Generally std::map is implemented as a tree of key-value pairs, and not a hash map To use a map, you have to include the header file: // Include the map library #include
With shades Keys are sorted by using the comparison function Compare.Search, removal, and insertion operations have logarithmic complexity Maps are associative containers that store elements formed by a combination of a key value and a mapped value, following a specific order The recommended method to insert an element in a map is by using map insert() method
