WebMar 25, 2024 · Answer: Hashtable is a widely used data structure to store values (i.e. keys) indexed with their hash code. Hash code is the result of the hash function and is used as the value of the index for storing a key. If two distinct keys hash to the same value the situation is called a collision and a good hash function minimizes collisions. WebIn C++, the hash is a function that is used for creating a hash table. When this function is called, it will generate an address for each key which is given in the hash function. And if the hash function returns a unique hash number, then this hash function is …
