Re: '*' to 'X'..................

i am near to finish if i can do that......

for those who can help me....

thhank you...

(Airplane Seating Assignment) Write a program that can be used to assign seats for a commercial airplane. The airplane has 13 rows, with 6 seats in each row. Rows 1 and 2 are first class; the remaining rows are economy class. Also, rows 1 through 7 are nonsmoking. Your program must prompt the user to enter the following information:

Here, * indicates that the seat is available; X indicates that the seat is occupied. Make this a menu-driven program; show the user’s choices and allow the user to make the appropriate choices.

You need to format and use code tags.


[code=cplusplus]
// paste code here
[/code]


Your code is very hard to read due to to the lack of indentation. You also have a whole bunch of extra brackets that do nothing. The compiler doesn't care about the extra brackets, but combined with the lack of indentation, it makes it hard to tell where code blocks begin and end.

You already have your array set up. When a person buys a seat, he/she will be assigned a row and a seat. '*' means the seat is empty, 'X' means it is taken. So when you reserve a seat at row myRowNum and seat mySeatNum, you'll do this:
C++ Syntax (Toggle Plain Text)
  1. plane[myRowNum][mySeatNum] = 'X';

Depending on how you want to organize your program, you'll need to change the userInput function so that it can somehow do something with that row and seat number once you get valid input. You'll either need to pass it your array or pass the row and seat numbers by reference so you can use them when the function returns to main(), or something similar.

Re: '*' to 'X'..................

Lot's of things.

My first tip, never write more than a few lines, and clearly never more than a single action, without compiling and testing. By doing that you would find that you are overwriting your array and getting junk. Be sure you can initialize all elements of the variable plane to valid default values and display the state of the plane before you do anything else.

Re: '*' to 'X'..................

Can you please use code tags and indent your code well for proper reading. I bet alot of people here are not trying to read the code because it is really not easy to read. Stop having the mentality that you are a newbie and you dont know anythin. Remeber people learn from their mistakes and if it has already been pointed out then please try to change. More infomation here and here. Please make a point to read both links
