The "C Language" address book is implemented.

Implement an Address Book: Contacts are used to hold 1000 people's information, each person's information includes: name, gender, age, telephone, Address Provision Method: (1) Add contact information (2) Delete the specified contact information (3) Find information for the specified contacts (4) Modify the specified contact information (5) Show all contact information (6) Clear all Contacts implementation method:
