// Input: number of rows, number of seats,seat selection, and user answer (y/n)

// Output: display the # of rows and seats, display a message if all seats are taken,

// and display a dash character '-' when the seat identifier is replaced

// Verify that a valid row and seat were entered

// See if all the seats are taken

// hint, keep a count each time a seat is taken

// and compare to the maximum number of seats (NumberOfRows*seats)

// See if the seat selection is already taken (see if it has an '-')

// if it has an '-', display a message that the seat is taken

}

char **CreateArrayOfSeats(int NumberOfRows, int SeatsOnRow) // ** means pointer to pointers

{

char **ArrayOfSeats;

ArrayOfSeats[r][s] = 'A' + s; // put 'A' 'B' 'C' etc in each row

}

}

void DisplayArrayOfSeats(char **ArrayOfSeats, int NumberOfRows, int NumberOfSeats)

{

for (int r = 0; r < NumberOfRows; r++) // for each row

{

cout.width(2);

cout << r+1 << ' '; // Display row numbers starting from 1

for (int s = 0; s < NumberOfSeats; s++)

cout << ArrayOfSeats[r][s] << ' '; // Display info for each seat

cout << endl; // new line after each row

}

}

void MemoryCleanup(char **ArrayOfSeats, int NumberOfRows, int NumberOfSeats)

{

for (int r = 0; r < NumberOfRows; r++)

delete [] ArrayOfSeats[r]; // delete each row of seats individually

delete [] ArrayOfSeats; // delete the row array

}

My question is how to get the

Output: display the # of rows and seats, display a message if all seats are taken,

and display a dash character '-' when the seat identifier is replaced inside the " do Loop " ?

Explanation / Answer

//hope this bit of code will help you
class ResevationSystem
{
static void Main()
{
int seatsFirst, seatsEconomy, reserve, i = 0, j = 6;
//This come sunder the seating chart
bool[] seats = { false, false, false, false, false,false, false, false, false, false };
Console.WriteLine("Welcome to the Reservation System.");
while (true)
{
Console.WriteLine("There are " + checkFirstClass(out seatsFirst, seats) + " first class seats and " + checkEconomy(out seatsEconomy, seats) + " economy seats.");
Console.WriteLine("Please enter 1 to reserve a first class seat or enter 2 to reserve an economy class seat or 0 to exit");
//here we will take the input form the person/user
reserve = Convert.ToInt32(Console.ReadLine());
if (reserve == 1)
{
if (i > 5 || i == 5)
{
//here u can add a dash symbol or anything which you want to display to the user
Console.WriteLine("There are no first class seats available. Would you like to move on to economy class seat? Type 2 for yes and 0 to exit.");
Here the program will go back to first depends on the usr request it will perfom
reserve = Convert.ToInt32(Console.ReadLine());
}
else reserveFirstSeat(ref seats, ref i);
