C Language Address Book

Implement an address book;
Contacts can be used to store 1000 of people's information, and each person's information includes:
Name, gender, age, telephone, address

Available methods:
1. Add contact information
2. Delete the specified contact information
3. Find specified contact information
4. Modify the specified contact information
5. Show all contact information

6. Clear All contacts
