Build a command-line phonebook that allows you look up the office, phone number, and email address of people on the struct implement the find functions

Build a command-line phonebook that allows you look up the office, phone number, and email address of people on the struct

implement the find functions in commands.c to find entries in the faculty array

Useqsort() and bsearch()

Note that you will need to implement functions to compare two professor structs based on their fields

Modify main.c to:

Use argc, argv, and bsearch() to find the appropriate find command function pointer from the commands table

Use the pointer to call the appropriate find function from commands.c in order to search the faculty array for the given arguments

Print the matching record

EXAMPLE:

$ ./phonebook email Usage: phonebook $ ./phonebook email KoAndrew@university.edu Ko, Andrew CS-538 (657) 238-2998 KoAndrew@university.edu
