Question

Would anyone please help me figure out why my void printMessage(char name[],char num[]); and int loginMatch(int passcode,int adminPasscode); are not working correctly in my c program? Thank you.

Here is the code:

6 #include <stdlib.h>

7 #include <time.h>

8 #include <string.h>

10 #define ROW 6

12 #define MAX 25

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

15 void displayMenu();

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

17 int loginMatch(int passcode, int adminPasscode);// my passcode is 10506//

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

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

305 }

This is what the function is supposed to do:

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

//DO THIS, IS IF YOU ARE DOING THE BONUS

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

SAMPLE OUTPUT:

1.) COU ----> MIA

2.) COU ----> BNA

3.) COU ----> LAS

Choose a flight:

Enter your first name:

Sue

O X O O

O O O O

X O O O

O O O O

Which Seat row do you want? :

Which seat column do you want? :

Sorry!! someone has reserved that seat. Please Try Again.

Which Seat row do you want? :

Which seat column do you want? :

Your requested seat has been reserved

O X O O

O O O O

X O O

//Chosen seat $500

O O O O

Congrats Sue, your flight LAS1050 is booked, enjoy your trip.

Your e-ticket number is : SLuAeS1050

Enjoy your Thanksgiving Break :)

Explanation / Answer

There are certain concerns with the functions and their usage:

loginMatch is a simple function.

The way it is called in the code:

result = (loginMatch(passcode, adminPasscode) == 0);

it can be simply called as :

result = loginMatch(passcode, adminPasscode) // You should definately get the right result

2. PrintMessage

The current code of the PrintMessage has print statements which are not correct, they
might give you a segmengtation fault.

for example
printf("Your flight %d is booked. Your e-ticket # is: ", &num);

%d is given and the argument is &num (Not correct)

printf("%s %s", name[i++], num[j++]);

%s is given and the argument is num[i++] (Not correct)
num[i++] is a character and not string.

Please correct the print statements in order to check your logic and call the loginMatch
function in a simpler way.
