In C programming:
This program involves implementing a simple Car Rental System that will allow the user to read, store, and manipulate customer data through a friendly text-based interface. During execution, the program stores all customer data in a linked list, and upon termination this data is automatically saved into a text file.The function definitions in file "proj-part1.c" are basically empty. Your main task in this project is to fill in the missing code based on the following descriptions of what each function is supposed to do. Empty functions and .txt files shown (cars.txt, customers.txt)
