WebA Hash table is basically a data structure that is used to store the key value pair. In C++, a hash table uses the hash function to compute the index in an array at which the value needs to be stored or searched. This process of computing the index is called hashing. Values in a hash table are not stored in the sorted order and there are huge ... WebApr 9, 2015 · Requires: p points to at least n contiguous bytes of input.
