CS Assignment 2 Solved

In this assignment, you need to write a program that allows users to make daily dinner reservations at local restaurants. The program simulates online restaurant reservations systems. This involves designing three classes: RestaurantReservations, Restaurant, and Reservation. All class attributes must be private and accessed through public member functions.

The attributes of each class are summarized below:

RestaurantReservations class has the following private attribute:
vector <Restaurant> restaurants;    // list of local restaurants

Restaurant class has the following private attributes:
string restaurantName;    // restaurant name
string restaurantAddress;    // restaurant address
string restaurantCity;    // restaurant city
string restaurantType;    // type of food served at restaurant
int availableSeats [4];    // array holding number of available seats at
// four possible times: 5, 6, 7 and 8 pm
vector <Reservation> reservations;    // list of reservations at this restaurant

Reservation class has the following private attributes:
const long reservationNum;    // reservation number which is set
// to the value of nextReservationNum
string contactName;    // name of person making reservation
string contactPhone;    // person phone number
int groupSize;    // number of persons in reservation
int reservationTime;    // reservation time which could be 5, 6, 7 or 8
static long nextReservationNum;    // initialize it to 100 and increment it by 10
// as you create a new Reservation object

For each class, you need to write an appropriate constructor, accessor and mutator functions as needed. The member functions for the RestaurantReservations class are summarized below:

    • void RestaurantReservations::ProcessTransactionFile(string fileName)

This function opens the transaction file, named fileName and processes its lines one by one. Each line contains a specific command along with its required data. The commands and their formats are:

    o CreateNewRestaurant rName rAddress rCity rType rCapacity o FindTable rCity rType rGroup rTime

o  FindTableAtRestaurant  rName rGroup

    o MakeReservation rName cName cPhone rGroup rTime o PrintAllRestaurants

o  PrintRestaurantReservations  rName

A sample transaction file is shown later. If the file could not be opened, you should print an appropriate error message.

    • void RestaurantReservations::CreateNewRestaurant ( string rName, string rAddress, string rCity, string rType, int rCapacity)

This function creates a new Restaurant object by calling the appropriate constructor and adds it to the restaurants vector. The reservations vector is initially empty and is updated later in the makeReservation method. The array availableSeats’s elements are all set to the value of rCapacity. The remaining restaurant attributes are set to the argument values rName, rAddress, rCity, and rType.
    • void RestaurantReservations::PrintAllRestaurants()

This function prints summary information of all restaurants in the restaurants vector. You should print the restaurant name, address, type, and capacity in a neat table format. For example:

Restaurant    Address, City    Type    Capacity
---------------------------------------------------------------------
LaPizzeria    4365NobleDr, SanDiego    italian    20
…

    • void RestaurantReservations::FindTable(string rCity, string rType, int rGroup, int rTime)

This function searches for all restaurants in a specific city, rCity, of a specific type, rType, and having at a specific time, rTime, enough seats for a given group of people, rGroup. If such restaurants are found, the function prints the names of all such restaurants. For example:

FindTable SanDiego italian 10 5

You may reserve a table for 10 at 5 pm at:

LaPizzeria

Civico

Otherwise, it prints an appropriate error message.

FindTable SanDiego italian 10 5

No restaurant can accommodate such a group at this time, check another time

    • void RestaurantReservations::FindTableAtRestaurant (string rName, int rGroup) This function finds all possible availabilities for a given group of people, rGroup, at a specific restaurant whose name is rName. In other words, it prints the possible times at which such a group can reserve a table at this restaurant. For example:

FindTableAtRestaurant LaPizzeria 2
You can reserve a table for 2 at LaPizzeria at 7:00 pm, 8:00 pm

If the restaurant name is invalid or the restaurant can not accommodate such a group at any time, this function prints an appropriate error message.


FindTableAtRestaurant LaPizzeria 8

LaPizzeria does not have such availability

    • void RestaurantReservations::MakeReservation (string rName, string cName, string cPhone, int rGroup, int rTime )

This function creates a new Reservation object and adds it to the reservations vector of the restaurant whose name is rName. You can use the push_back function to add the new object at then of the vector. The customer name, phone, group and time should be set to cName, cPhone, rGroup, and rTime respectively. reservationNum for the new object should be set to the value of nextReservationNum and then nextReservationNum should be incremented by 10. The function also updates the available seats array at that specific time. Note that the first array element corresponds to the available seats at 5:00 pm. The second corresponds to the availabilities at 6:00 pm and so on.

    • void RestaurantReservations::PrintRestaurantReservations (string rName)

This function prints the details of all reservations at the restaurant whose name is rName. Details include the following information: reservation number, customer name, phone number, group size and reservation time. For example:

PrintRestaurantReservations Barrio

Reservation    Contact    Phone    Group    Time

Note: Any member function that does not modify the attributes must be made constant.

After designing your classes (and breaking up your classes into .cpp and .h files), write a main program that instantiates an object of type RestaurantReservations and calls a method to read a transaction file and process its commands. Your main should look like this:


int main()
{

RestaurantReservations openTable; openTable.ProcessTransactionFile("TransactionFile.txt");

return 0;
}

Then test your code by including the following commands in your transaction file:

Once done, you need to submit the following:

    1. A hard copy (printed copy) of the source codes (RestaurantReservations.h, Restaurant.h, Reservation.h, RestaurantReservations.cpp, Restaurant.cpp,

Reservation.cpp, and main.cpp) and the output run placed in a folder. You should hand in the folder during the first 5 minutes of the class when the homework is due. You lose 10% of the grade if you do not provide a complete folder.

    2. An electronic copy of your source code (no output). You should place all source codes and executable file in a zipped folder and name it based on your first/last name and the assignment number. For example, JoeSmith-A1.zip. You should submit the zipped folder online through cougar website.
