hello,i'm yuri and i'm new here..
i have to make program about airline seating..
but up till now..we still have some problems with the program..
it's not working as we expect it to be..
so,i'm asking anybody that can help me..please..
i'm quite desperate now..we've been work on this program for 3 weeks...*_*

this is the question:

Airline seating:write a program that assigns seats on airplane.assume that airplane has 20 seats in first class(5 rows of 4 seats each,separated by an aisle) and 180 seats in economy class(30 rows of 6 seats each,separated by an aisle). Your program should take three commands, add passengers, show seating(use ‘*’ to indicates that the seat is available; ‘X’ to indicates that the seat is occupied), and quit. When passengers are added, ask for the class(first or economy), the number of passengers traveling together(1 or 2 in first class;1 to 3 in economy), and the seating preference(aisle or window in first class; aisle, center, or window in economy). Then try to match and assign the seats. If no match exists,print a message.

please help me anyone...

Look it up. It's a forum thing on this website.

I recommend you to use the following code as a basis. I left the most difficult part (implementing addPassengers) to you. But like this the code becomes much more readable than yours. (in fact i just reorganized yours).

Feel free to adjust the code to your needs.

Do you have more specific questions?

Yours, Maikel
