Elements of a hash map are identified by key values, while the mapped values are the content associated with the keys. Each element of a map or unordered_map is an object of type pair. A pair object has two member variables: have a live

"WebA chained hash table will never need to be resized. Implementation of Chaining. Let's write a hash function to ensure that our hash table has 'N' buckets. To add a node to the hash table, we must first determine the hash index for the given key. It could also be computed using the hash function. Example: hashIndex = key % noOfBuckets " - Hash data structure c++
