"C Language" implements an 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

Main function:

#include "contact.h" void Shou_menue () {printf ("*********************************\n");p rintf ("*  1: Add contact    2: Delete Contact *\n ");p rintf (" *  3: Find contact    4: Modify Contact *\n ");p rintf (" *  5: Show Contact    6: Clear Contact *\n ");p rintf (" ************* \ n ");} int main () {struct contact My_contact;int input = 1;my_contact.count = 0;while (input) {shou_menue ();p rintf ("Select the action you want:") ; scanf ("%d", &input), switch (input) {case 1:add (&my_contact); Break;case 2:dele (&my_contact); Break;case 3 : Search (&my_contact); Break;case 4:modify (&my_contact); Break;case 5:show (&my_contact); Break;case 6: Clear (&my_contact); break;default:break;}} return 0;}

The following is the result of the operation:

Add contacts and show contacts:

To delete a contact:

Find a Contact:

To modify a contact:
