Design a class template for the ADT Hash Table, using the implementation described in this section. The basic operations should include (at least) constructors, a destructor, a copy constructor, inserting an item into a hash table, searching for an item in the hash table, and deleting an item from the hash table.
Use random hashing for the hash function and chaining to resolve collisions. You should also write a driver program to test your class template as instructed in Programming Problem at the end of this chapter.
Problem ,
Write a program that reads a collection of computer user-ids and passwords and stores them in a hash table. The program should then read two strings representing a user's id and password and then check whether this is a valid user of the computer system by searching the hash table for this id and password.
