Program should accept the guest information until the user says 'n'. b. Store all the information in a hash table by using national ID as key field. C. i. Use any hash function to convert key into hash key. Write the code of separate chaining to place the records in hash table. d. Display all records from table whenever required. e. Delete a record whenever required. f. Write a menu driven code for the above steps. 1. A hotel room reservation in a famous hotel wants to store all the guest information in a database.
