Witryna18 lip 2024 · In C++, the sorted map ( std::map) is usually implemented as a binary tree, and the unsorted map ( std::unordered_map) is a hash table with closed addressing. A hash table can deliver O (1) lookup time, whereas a binary tree has O (log n) lookup. This means the number of elements in a hash table doesn’t influence the lookup speed.

In C++ we also have a feature called “hash map” which is a structure similar to a hash table but each entry is a key-value pair. In C++ its called hash map or simply a map. Hash map in C++ is usually unordered. Witrynastd::map is a sorted associative container that contains key-value pairs with unique keys. Keys are sorted by using the comparison function Compare.
