Question

I need help fixing this code and adding a loop please.

Here is the original problem:

A theater seating chart is implemented as a two-dimensional array of ticket prices, like this: 10 10 10 10 10 10 10 10 10 10


#include <iostream>

using namespace std;

//function to print seating chart
void printSeatingChart(int **chart)
{

   int i, j;

   cout << "\nROW\t";
   for (i = 1; i <= 10; i++)
   {
       cout << i << "\t";
   }
   cout << "\n-----------------------------------------------------------------------------------\n";
   for (i = 8; i >= 0; i--)
   {

       cout << "\n" << i + 1 << "\t";
       for (j = 0; j < 10; j++)
       {
           cout << chart[i][j] << "\t";
       }
       cout << endl << endl;
   }
}

//function to book the seat based on position
void seat(int **chart, int i, int j)
{
   //if given position is not booked
   if (chart[i][j] != 0)
   {
       chart[i][j] = 0;
       printSeatingChart(chart);
       cout << "Seat is booked..\nThank you." << endl;
   }
   //already booked
   else
   {
       cout << "Seat is already sold.." << endl;
   }
}
//function to book the seat based on price
void price(int **chart, int price)
{

   int i, j, flag = 0;
   for (i = 9; i >= 0; i--)
   {
       for (j = 0; j < 10; j++)
       {
           if (chart[i][j] == price)
           {
               flag = 1;
               chart[i][j] = 0;
               printSeatingChart(chart);
               cout << "Seat is booked..\nrow: " << i + 1 << "\ncol: " << j + 1 << "\nThank you." << endl;
               break;
           }
       }

}

int main()
