here is full question

Write a program that can be used by a small theater to sell
tickets for performances. The theater s auditorium has 15 rows of seats, with 30 seats
in each row. The program should display a screen that shows which seats are available
and which are taken. For example, the following screen shows a chart depicting
each seat in the theater. Seats that are taken are represented by an * symbol, and seats
that are available are represented by a # symbol:

  #include <iostream>
#include <iomanip>
#include <string>
#include <istream>
#include <fstream>
using namespace std;

const int numberOfRow = 15;
const int numberOfCol = 30;

void print(char matrix[][30], int numberOfRow, int numberOfCol);

int main()
{
char matrix[numberOfRow][numberOfCol], seat[numberOfRow][numberOfCol];
char option;
int i, j;
int row,col;
int ticketsold = 0;
bool another =true;

for(i = 0; i < numberOfRow; i++)
    for(j = 0; j < numberOfCol; j++)
        matrix[i][j] = '*';

while(another)
{
    print( matrix, numberOfRow, numberOfCol );

    cout << "\nMenu:\n";
    cout << "1)  Buy ticket\n";
    cout << "2)  Total sell and exit\n\n";
    cout << "Enter your choice  : ";
    cin >> option;
    cout << endl << endl;

    switch (option)
    {
    case '1' :
        {
            cout << "Enter row: ";
            cin >> row;
            cout << "\nEnter seat: ";
            cin >> col;

            if( matrix[row][col] == '*')
                {
                    matrix[row][col] = '#';
                    ticketsold++;
                }
              else
                { 
                  cout << "Invalid seat choice";
                }


            //total revenue
        }

    case '2' :
        {
            another=false;
        }

    default :
        cout << "Invalid choice";

    }
}




}


void print(char matrix[][30], int numberOfRow, int numberOfCol)
{
int row, col, i, j;

cout << "* Seats available\n";
cout << "# Reserved Seats\n";
cout << "Seats:  0  1  2  3  4  5  6  7  8  9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29" <<  endl;

for(i = 0; i < numberOfRow; i++)
{
    cout << "Row" << setw(3) << i;
    for(j=0; numberOfCol > j; j++)
        cout << setw(3) << matrix[i][j];

    cout << endl;
}
}

line 15: What's the purpose of the seat array? You don't need it.

line 24,48,48,81,82: You have the characters for taken and available reversed. The instructions state * is taken and # is available.

i want to add an array which ask for price for each rows because each row has different price row 1 has 1000 then row 2 500 user will enter the price of rowa how should i add it

The instructions don't indicate that is a requirement. However, if you want to add that feature, I would suggest starting with a const array of prices, rather than prompting for the price of each row.

  const int prices[numberOfRow] = {  <15 prices> };

Once you have your program working with an array of prices, then it's easy enough to change it to prompt for the price of each row if you wish.

when i booked a ticket from option 2 and want to see how many seats are booked option 4 does not show me so much confusion

[AbstractionAnon]

line 13: price is an unnecessary global. Get rid of it. Causes reader confusion with line 21.

line 10, 20: Duplicate constants for the same purpose. Get rid of one.

line 8,9: Good move declaring const values for FULL and EMPTY. However at line 67, you don't use the const value.

line 75: You adjust the total before the purchase is confirmed. If the user says no, total is going to be wrong.

line 89, 94: If the user says no, you ask "Would you like to look at another seat?" twice.

and want to see how many seats are booked option 4 does not show me

Option #4 doesn't do anything.

case 4:
				cout << "View Seat Sales\n\n";
				break;

I strongly suggest moving lines 59-97 to a separate function. Makes your program easier to read.

[wahab13796]

oh shit i have duplicate many lines thanks man

can u move the lines into a seperate function and give me code with bug free?

[wahab13796]

option 4 code is missing means i have to write code for it

[wahab13796]

i m confuse how to use full and empty in line 67 then properly

[wahab13796]

i m tired of this can u plz give me this in working condition :(

[TheIdeasMan]

i m tired of this can u plz give me this in working condition :(

Realise that respondents might be in a different time zone to you.

can u move the lines into a seperate function and give me code with bug free?

You already have functions in your program, why can't you do it? It's your job to write code, ours to help out. AbstractionAnon has already given you a great deal of help.

[AbstractionAnon]

i m confuse how to use full and empty in line 67 then properly

Just use the name of the character literal you defined.

if (map [row2] [column2] == FULL)

i m tired of this can u plz give me this in working condition

Sorry. I'm not going to write your assignment for you. You will learn more by doing.
Post some updated code and I will try to give you as much help as I can.

thnaks guys its done now
