Below is the definition of unordered maps in c++ template< class k , class t,class hash = hash < k >, classpred = equal_to < k >, classalloc = allocator < pair < constk, t >> >. By calling reserve with the size we expected for the unordered_map container we avoided the multiple rehashes that the increases in container size could have produced and optimized the. Unorderedmap is basically a wrapper for std::unordered_map that supports storage of windows runtime types.

This defaults to hash, which returns a hash value with a probability of collision approaching 1.0/std::numeric_limits::max(). I have primarily implemented the unordered version using the hash function, i used it this way. Map (like set) is an ordered sequence of unique keys whereas in unordered_map key can be stored in any order, so unordered.
