How would I create a C program?

This

application helps in reserving flight seats. This is done via implementing the 8 user-defined

functions as explained below.

Your program must print a menu for the user to select what he needs to do with the application.

There will be admin mode which requires log-in via a passcode. There will be an option for

reserving a seat on a flight. Third option is to exit the application.

Comments and prototypes have been given for you to help you out in the process.

GLOBAL CONSTANTS and VARIABLES:

#define ROW 6 //for row length

#define COL 4 //for column length

#define MAX 25 // for strings

int costMatrix[ROW][COL]={{500,200,200,500},

{500,200,200,500},

{500,200,200,500},

{500,200,200,500},

{500,200,200,500},

{500,200,200,500}};

Functions to implement:

1.

void initialSeats(char flight[][COL], int count);

The

initialSeats

function takes in a two-dimensional

char

array created in main. It will initialize

all array elements to the character

O. O

symbolizes the seat on the plane is open and can be

taken. The

int count

parameter is used to symbolize the number of people who already have a

seat on the plane; this is a random number sent from main (use rand() to send this number). In

this function it will randomly create and assign an index in the two-dimensional array with the

character

X

for each person up to value of

count

.

X

is used to symbolize that an element in

the two dimensional array is occupied. This will be used later on in the program.

MAKE SURE

TO SEED RAND in MAIN.

Below is the way to randomly generate the seats for each

passenger to take. This function should be called as soon as your program starts.

Keep in mind

the possibility of the randomized index overwriting

X,

if it was already there.

You have to handle that case. Beware!!

int row = rand() % ROW;

int col = rand() % COL;

2.

void displayMenu();

Prints the display options. Admin mode, Reserve a seat and Exit. This is the main menu.

3.

void printFlightMap(char flight[][COL]);

The printFlightMap function is printing off a two-dimensional character array. Thus, printing off

the characters stored in each index of the two-dimensional array either O or X. As noted

above the ROW and COL are #defined in your program, use them. For loops are your friends

here. Called in admin mode and during reserving a seat (specifically in seatReservation).

4.

int loginMatch(int passcode,int adminPasscode);

The loginMatch function is called to compare a pair of integers, the function returns 1 if both

numbers match and 0 if there is no match. This is called with the number the user entered and the

admin password. This is called in admin mode.

5

.

int getTotalRevenue(char f1[][COL], char f2[][COL], char f3[ ][COL]);

Note: f1, f2, f3 are flight1, flight2, flight3, just shorthanded.

The getTotalRevenue function will take in all three two-dimensional character arrays created in

main and calculate the total revenue using the costMatrix two dimensional array. With each two-

dimensional array f1, f2, and f3, search for the character X stored in them, upon finding the

index of the character X, use the index to reference inside of the global two-dimensional array

costMatrix (look above in Constants and Global Variables).

While inside of costMatrix array,

add the value stored in the two-dimensional array with a running total variable (Hint use +=).

The function will return the total revenue earned thus far from seats reserved in all 3 flights. So,

you will need

nested for-loops

. This is called only in admin mode.

6.

void flightMenu();

Prints the three flight options as shown. Flights to Miami, Nashville and Las Vegas. This is done

when reserve a seat option is chosen.

7.

void seatReservation(char flight[][COL]);

The seatReservation function takes in a two-dimensional array and allows the user to reserve an

index on the two-dimensional array. Before any reserving is done, this function calls the

printFlightMap

function mentioned earlier to allow the user to

see

the already populated two-

dimensional array for that flight. Then, the user is asked to enter a row and column to reserve a

seat. Additionally, this function

will have built in error checking (look below at output

example)

Once the user has inputted a correct index within [0, ROW) and [0, COL) in the two-

dimensional array, this function needs to check if that index entered is already taken in the two-

dimensional array with the character

X.

If the index is populated with

X

, an error will be

shown to the user (

look at the output below

) and have them re-enter a new possible row and

column again. If the index entered is not filled with X, then assign that index with

X

, i.e.

changing the element from

O

to

X

. Before the function ends, it will call the function

printFlightMap

again and prints a success message.

Remember rows run from 0-5 and columns from 0-3. Error check for this too.

8.

void printMessage(char name[],char num[]);

This function is called for each flight option after the seatReservation() is called. It takes in two

strings, name of passenger and the flight number for that particular case. Both are character

arrays (strings). For flight Cou->Miami number must be set as MIA1050, for Cou->Nashville

number must be set as BNA1050, for flight Cou->Las Vegas num must be set as LAS1050,

this must be done in main and the name and particular number must be sent to this function.

Once in this function, you will merge (important part) the two strings into third string and print

that as the e-Ticket as shown below and print a confirmation message.

Eg1: name is Fred number is MIA1050, your merged string should be FMrIeAd1050. Print

this as the booking confirmation number.

Eg2: name is Guilliams number is LAS1050, you merged string should be

GLuAiSl1l0i5a0ms.

Eg3: name is Christopher number is BNA1050, your merged string should be

CBhNrAi1s0t5o0pher

9.

int main(void)

The main function will be doing all (most of) the function calls. In main, you will need to create

four character arrays of

flight_1[ROW][COL]

,

flight_2[ROW][COL]

,

flight_3[ROW][COL]

,

and strings

name[MAX],flight_number[MAX]

adminPasscode

= 105016;

Also, before you call

initialSeats

function on all the flights arrays individually, make sure to find

how many people already reserved seats. This is done by creating a local variable

seats = rand % 5 + 1 (this is your

int counts

in initialSeats function), rand()%5 +1 will give a

random number between 1-5; you only need to do this once. A menu system will be displayed

for the users to run specific parts of the program (See output below of what the menu system

needs to look like).

Make sure to implement error checking for invalid input!

On the main menu, the user will see a display of options: The options are 1: Admin Portal, 2:

Reserve a seat on a flight, and 3: Quit. The menu will need to loop until the exit option is

chosen.

To access the

Admin Portal,

the user enters a 1, and then must type a passcode that will be

stored in a variable

.

Now, verify the passcode, call the

loginMatch

function (you should

compare) with passcode and adminPasscode to verify if it is an authentic log-in attempt. If the

pair

match, that is, they are equivalent then it means successful log-in. Upon successful

verification, inside of the admin portal, call

printFlightMap

on each flight array and

getTotalRevenue

(See output below). Declare these variables in main().

To access

Reserve a seat

, the user enters a 2. Inside of this portal, the user is displayed the three

flights that can be accessed to book a seat. (See below output).

As always

verify the user input

for flight option (1-5). 2 character arrays will be used, name and flight_number. Once a valid

flight option is chosen. Ask for the users first name and store it in name[] and store the flight

numbers (MIA1050,BNA1050,LAS1050) in flight_number[] as specified above for that flight.

Then, send the corresponding flight array to

seatReservation

, after successful reservation the

user will be relocated back to the main menu. (If you are doing the bonus) then call the

printMessage with name[] and that particular flight_number[],

. Note: flight1 is Miami,

flight2 is Nashville, flight3 is Las Vegas.

Please go through Sample Output and the document clearly before starting out.

Sample Output

Character in bold are inputs from the user.

Yours will vary but the outline must look similar. It is big,

dont worry, but will help give you a better idea. I have run it twice completely, thats why it is 10

pages.
