I have an assignment for class to make program that will allow the user to input a number and a letter to assign them to a seat on a plane. There are 15 rows and 5 columns (A,B,C,D,E). The first five rows are for first class the rest are economy. After all seats for First class are taken we are supposed to ask the user if they would like to sit in economy and vice versa. I keep writing and writing code to try and check the array from row [0] to row [5] to see if all the first class seats are taken, but I have not found a way to do it. If I could find the solution to that then I could find the solution to check and see if there are any economy seats open.

I originally did this:

for (int i = 0; i <= 4; i++)
for (int j = 0; j <= SeatList.GetLength(1); j++)
if (SeatList[i, j] == false)
break;
else
{
Console.WriteLine("First Class seats are unavailable");
Console.WriteLine("Would you like a seat in Economy?");
Console.ReadLine();
}

It kind of works but it will write the else however many times there is a true element

If you need to see the whole program:


static void Main(string[] args)
{
// int row;
// int column;

// Variables
byte columnAlphabet;
char columnAlphabet2;
int intSeatRow;
int intNumberSeatColumn;
int columnForByte;
string strLetterSeatColumn;
string strQuit;
string strQuit2;

// Constants for array
const int intFive = 5;
const int intFifteen = 15;

// Initializing Variables
intNumberSeatColumn = 0;
strQuit = "Quit";
strQuit2 = null;

// Seat Array
bool[ , ] SeatList = new bool[intFifteen,intFive];

// DO WHILE, Infinte loop because if statement checks when to exit
do
{
// Initializing Variables
intSeatRow = 0;
strLetterSeatColumn = null;

Console.Clear();

// To display the seating chart
for (int row = 0; row < SeatList.GetLength(0); row++)
{ // For converting column to ASCII for a Letter
columnForByte = 63;
for (int column = 0; column < SeatList.GetLength(1); column++)
{
// Converting column number to ASCII for a letter
columnForByte = columnForByte + 1;
columnAlphabet = Convert.ToByte(columnForByte);
columnAlphabet2 = Convert.ToChar(columnAlphabet + 1);
Console.Write("Seat {0,2}{1,1} {2,5}", (row + 1), (columnAlphabet2), SeatList[row, column]);
Console.WriteLine();
}
}
// Getting input from user for which row they would like or 999 to exit
Console.WriteLine();
Console.WriteLine("Rows 1-5 are First Class, Rows 6-15 are Coach");
Console.WriteLine("Which Row would the passenger like? (Or Type 999 to exit)");
intSeatRow = Convert.ToInt32(Console.ReadLine());

// Checking to see if user wants to exit
if (intSeatRow == 999)
{
break;
}

// Validating that good data is input
if (intSeatRow > 15 || intSeatRow < 0)
{
Console.WriteLine();
Console.WriteLine("INVALID, Please retype");
Console.WriteLine("Press Enter when done");
Console.ReadLine();
continue;
}

// Only running if Row number was valid
if (intSeatRow <= 15 || intSeatRow > 0)
{
Console.WriteLine("Which Letter seat would the passenger like?");
strLetterSeatColumn = Console.ReadLine();
strLetterSeatColumn = strLetterSeatColumn.ToUpper();
}

// Changing letter to a number for column index
switch (strLetterSeatColumn)
{
case "A":
intNumberSeatColumn = 0;
break;
case "B":
intNumberSeatColumn = 1;
break;
case "C":
intNumberSeatColumn = 2;
break;
case "D":
intNumberSeatColumn = 3;
break;
case "E":
intNumberSeatColumn = 4;
break;
default:
Console.WriteLine("INVAILD, Please Retype");
continue;
}

// Checking if desired seat is taken
if (SeatList[intSeatRow - 1, intNumberSeatColumn] == true)
{
Console.WriteLine("We're sorry that seat is taken");
Console.WriteLine("Press Enter when done");
Console.ReadLine();

for (int i = 0; i <= 4; i++)
for (int j = 0; j <= SeatList.GetLength(1); j++)
if (SeatList[i, j] == false)
break;
else
{
Console.WriteLine("First Class seats are unavailable");
Console.WriteLine("Would you like a seat in Economy?");
Console.ReadLine();
}
}

// Reserving seat if seat not already taken
if (SeatList[intSeatRow - 1, intNumberSeatColumn] == false)
SeatList[intSeatRow - 1, intNumberSeatColumn] = true;

Console.Clear();
// Displaying Assigned seat
Console.WriteLine("You are assigned to seat {0}{1}", intSeatRow, strLetterSeatColumn);
Console.WriteLine("Press Enter when done");
Console.ReadLine();
} while (strQuit != strQuit2); // Infinite Loop because the If statement checks for Exit

Console.WriteLine("\nPress Enter When Done");
Console.ReadLine();
}
}
}



Any help is appreciated.
