please help is two parts in this program.

You will be submitting two separate projects. See Part A and Part B for details. o All of the functions making up this program are complete and in working order except for functions marked with /// FILL THIS FUNCTION. You will need to implement these functions. o The major challenge in this assignment is to divide the program into separately compiled modules. ? A reservation module with files reserved.h and reserved.cpp, containing code dealing specifically with updating the reservations array. ? A guest module, consisting of files guest.h and guest.cpp containing code dealing specifically with the guest records in the guest array. ? A table module with the files table.h and table.cpp containing code dealing with the array of tables and their availability based on time. ? There are some functions that are not specifically related to any of these modules, but are called by or contain code needed by certain modules. You should apportion these functions to the modules in a way consistent with the goals of high cohesion and low coupling. ? Consult the comments in the provided code for additional details. Problem description: A local restaurant has decided to upgrade their reservation system from a spiral notebook. They want a program that will store customer information including phone numbers and credit card information, so regular customers dont have to give the same information over and over. There are 3 options: New Reservation, View Reservations, and Cancel Reservations. Input Input to the program is taken from several text files containing Reservation data, Guest data, and Table data. These are included, but your program should function even if the information in the data files were to change with the format being the same. The first line in every file is the number of data points (lines) in the file. Output The output should be regular updates to the 3 files, as well as interactive menus and the reservation reports.

Part A: Create a project containing the file main.cpp. Implement the empty functions marked with ///Fill This Function comments. You will need understand the purpose of these function in order to implement them. Do this by looking for where the functions are being called and how the function is being used in the program. Also, there may be other function that do similar, though not the same task. These functions may give you a clue how to implement the empty functions. The program should compile and have expected Input and Output as outlined above. You will not need to split the functions into Modules for this portion. You DO need to create function declarations for each function and move main() to the top of the list of functions.

Part B: Create a project containing the files main.cpp, reserved.cpp, reserved.h, guest.cpp, guest.h, table.cpp, table.h. Split the functions from Part A into the appropriate modules as outlined in the general instructions. The program should compile and have the same input and output as Part A. In order to determine where a function belongs, look to see what functions it calls, and which functions it is called by. Functions which rely heavily on each other are good candidates for a module. Functions which are associated in purpose may also be candidates for a particular module.
