Please Help with Airplane Reservation Project

[drtran83]

Hello everyone,

I'm currently working a project for class and I am stuck. I am a complete newbie when it comes to programming and I am trying my best, so if my code looks off, please let me know where I am going wrong. I'm not looking for anyone to do my homework for me, just would like some help and to be pointed in the right direction. Anyways here are the guidelines for my project:

This program will allow the user to keep track of airline reservations. The program should display the seating chart for the airplane. It will use an * to indicate a seat is taken and the # to indicate the seat is available. The program will also display a menu which provides the user with several options. There will be two types of seats in the airplane: first class and coach, each of which will have a different cost. The program must make use of files, arrays and functions.

The airplane will have 5 rows in the first class section with 4 seats in each row, 2 on each side of the aisle and 10 rows in the coach section with 3 seats on each side of the aisle. The prices for all the first class seats will be the same. The first 5 rows of coach will be more expensive than the last 5 rows. The prices for the seats will be stored in a file called SeatPrices.txt . The program should read these values from the file and store the values in an array of doubles. This is an example of the seating chart:
12 34
Row 1 ## ##
Row 2 ## ##
Row 3 ## ##
Row 4 ## ##
Row 5 ## ##
123 456
Row 6 ### ###
Row 7 ### ###
Etc.

The menu will provide choices to reserve a seat(s) and display the total number of seats sold (indicating first class and coach), the total number of seats empty in a row, the total number of seats empty in the plane (indicating first class and coach), and the total amount of sales (in dollars).

Validation: The seat requested by the user is a valid row and seat number. The program should also make sure the seat is not already taken.

SeatPrices.txt

I am mainly having problem with my output for the seating chart, I don't know how to get the values of the array to show up as # and *. Can anyone please help me out with this??? Thanks ahead of time!!

I am mainly having problem with my output for the seating chart, I don't know how to get the values of the array to show up as # and *. Can anyone please help me out with this???

I would recommend a for loop. Like this:

	for (int x = 0; x < FirstROWS; x++)
	     for (int y = 0; y < FirstCOLS; y++)
		firstClassSeats[x][y] = '#';

Then another for loop like it for the Coach.

To convert the '#' to '*', I would recommend to use an if/else statement. Like this:


Once you select the row and the seat, you can use the if/else statement:

	
                       	cout << "What Row would you like to reserve?";
			cin >> rowFirstClass;

			cout << "What Seat would you like to reserve?";
			cin >> seatFirstClass;

		        if (firstClassSeats[rowFirstClass - 1][seatFirstClass - 1] != '*')
			{

				firstClassSeats[rowFirstClass - 1][seatFirstClass - 1] = '*';
				cout << endl << "======RESERVED======\n";
				countFirst++;
			}

			else
			{
				cout << "======SEAT IS OCCUPIED======" << endl;
			}

I hope it helps.

Thanks Chicofeo.

I added the code for the #, but now I'm getting a an error:

C2065 : 'y' undeclared identifier

here is what the code looks like:

for (int x=0; x < FirstROWS; x++)
{
     for (int y = 0; y < FirstCOLS; y++)

        FirstArray [x][y] = '#';

cout << FirstArray [x][y] << endl;

cout << endl;

}

not sure where I am going wrong here.

[chicofeo]

The y is undeclared, because of line 8
cout << FirstArray [x][y] << endl;

The 'y' variable is initialized only for the loop on line 4 and line 6:

 for (int y = 0; y < FirstCOLS; y++)
   FirstArray [x][y] = '#';

However, if you want to use line 8, then you would have to add the enclosing brackets like this:

     for (int y = 0; y < FirstCOLS; y++)
     {
        FirstArray [x][y] = '#';
        cout << FirstArray [x][y] << endl;
     }

The error C2065 : 'y' undeclared identifier should disappear.

[drtran83]

Thanks again so much Chicofeo.

I was able to fix it, but it still does not output the #, is there something else I am missing here?

here is a full line of code to hopefully output it...

for (int x = 0; x < CoachROWS; x++)
{
     for (int y = 0; y < CoachCOLS; y++)
    {
     Coach1Array[x][y] = '#';
     cout << Coach2Array[x][y];
     }
}

Take a look at line 50:

	double FirstArray[FirstROWS][FirstCOLS];
	double Coach1Array[CoachROWS][CoachCOLS];  
	double Coach2Array[CoachROWS][CoachCOLS];  

you should change it from double to char. You are using the array variables to allocate the character '#' to display the available seats and '*' for occupied seats. If you don't change it, then you will get random numbers or garbage.

For example:

	char FirstArray[FirstROWS][FirstCOLS];
	double Coach1Array[CoachROWS][CoachCOLS];
	double Coach2Array[CoachROWS][CoachCOLS];

	for (int x = 0; x < FirstROWS; x++)
		for (int y = 0; y < FirstCOLS; y++)
			FirstArray[x][y] = '#';

I did not change it all to give you the opportunity to work on it.

Take a look at lines 178-185

cout << "\nPlease pick which seat you would like to sit in, please enter between 1-6:  ";
cin >> fccol;

if (fcccol > 6) // Do you notice the difference between fccol and fcccol?
{
	cout << "You have entered an invalid seat number, please enter between 1-6";
	cin >> fcccol; // Is it fccol or fcccol?
}

Take a look at lines 205-214:

cout << "\nNow please pick which row you would like to sit in, please choose between 11-15 ";
cin >> scrow; 



if (fccrow > 15) // This variable is not initiated. Do you mean scrow?
{
	cout << "\nYou have entered an invalid row number, please enter in between 11-15 ";
	cin >> scrow; // You will get a run time error prior to arriving here that fccrow is not
	//initiated.
}

Take a look at the function :

void seatChart(char FirstArray[FirstROWS][FirstCOLS], double Coach1Array[CoachROWS][CoachCOLS],
	double Coach2Array[CoachROWS][CoachCOLS])
{
	cout << "This is the Seating Chart" << endl;
	cout << "========================= \n" << endl;

	cout << "# - Available Seats\n";
	cout << "* - Occupied seats\n";
	cout << "Available Seats for you are :\n";
	cout << "       1 2 3 4\n";
	for (int x = 0; x < FirstROWS; x++)
	{
		cout << right << setw(2) << "Row " << setw(2) << x + 1; // Use setw to adjust the spacing between characters, accordingly
		for (int y = 0; y < FirstCOLS; y++)
			cout << setw(2) << FirstArray[x][y];

		cout << endl;
	}

	//cout << "First Class is seats 1-4, Rows 1-5\n" << endl;

	//for (int x = 0; x < FirstROWS; x++)
	//{
	//	for (int y = 0; y < FirstCOLS; y++)
	//	{
	//		FirstArray[x][y] = '#';
	//		cout << FirstArray[x][y];
	//	}
	//	cout << endl;

	//}

	cout << "\nFirst Coach Class are seats 1-6, Rows 6-10:\n" << endl;

	for (int x = 0; x < CoachROWS; x++)
	{
		for (int y = 0; y < CoachCOLS; y++)
		{
			Coach1Array[x][y] = '#';
			cout << Coach1Array[x][y];
		}
	}

	cout << endl;

	cout << "\nSecond Coach Class are seats 1-6, Rows 11-15\n" << endl;

	for (int x = 0; x < CoachROWS; x++)
	{
		for (int y = 0; y < CoachCOLS; y++)
		{
			Coach1Array[x][y] = '#';

			cout << Coach2Array[x][y];
		}
	}

	cout << endl;

}

I made some suggestions to give you an idea to work on it.

[drtran83]

Thank you so much Chicofeo! I'll work on everything you helped me with and if there is anything else I'll let you know.
