Chapter 19 Exercise 4

leodemario · July 22nd, 2011, 11:03 PM

Hello!

When I try to write this part:

else
{
int row;
int seat;
GetNextFreeSeat(out row, out seat);
resp.Row = row;
resp.Seat = seat;
}

The GetNextFreeSeat method is not defined in the context.
Somebody can help me with this?

Thanks in Advance.

All this should be part of excercise 3, the implementation of the service.
GetNextFreeSeat could look like this:

Code:

        private void GetNextFreeSeat(out int row, out int seat)
        {
            row = -1;
            seat = -1;
            for (int r = 0; r < maxRows; r++)
            {
                for (int s = 0; s < maxSeats; s++)
                {
                    if (!this.reservedSeats[r, s])
                    {
                        row = r;
                        seat = s;
                        return;
                    }

                }
            }
        }

Hope this helps.
