Need help with 2-D array print out

crizzo · #1 27-Jun-2004, 02:01

I have a problem where I have to print an airline seating chart and represent vacant seats with an asterick. I have the program working correctly, but I can't figure out how to print "Row 1", "Row 2", etc. at the beginning of each row when printing the array. Here is the part of the code where I initialize and print the array:

CPP / C++ / C Code:

#include <iostream>
#include <iomanip>

using namespace std;

const int rows = 13;
const int columns = 6;
int row;
int col;
char seatChart[rows][columns];

//function prototypes
void initSeatArray(const int, const int, int, int, char[13][6]);

void main ()
{
	initSeatArray(rows, columns, row, col, seatChart);
}
	

//Funtion Definitions

void initSeatArray(const int rows, const int columns,int row, int col, char seatChart[13][6])
{
	for(row=0; row<rows; row++)
	for(col=0; col<columns; col++)
		seatChart[row][col] = '*';
		
	cout<<"Any seat marked with an asterick is available.\n";
	cout<<setw(5)<<"A"<<setw(6)<<"B"<<setw(6)<<"C"<<setw(6)<<"D"<<setw(6)<<"E"<<setw(6)<<"F"<<endl;
		
	for(row=0; row<rows; row++)
	{
		for(col = 0; col<columns; col++)
			cout<<setw(5)<<seatChart[row][col]<<" ";
			cout<<endl;
	}
}

The output looks like this:

Any seat marked with an asterick is available.

Code:

    A     B     C     D     E     F
    *     *     *     *     *     *
    *     *     *     *     *     *
    *     *     *     *     *     *
    *     *     *     *     *     *
    *     *     *     *     *     *
    *     *     *     *     *     *
    *     *     *     *     *     *
    *     *     *     *     *     *
    *     *     *     *     *     *
    *     *     *     *     *     *
    *     *     *     *     *     *
    *     *     *     *     *     *
    *     *     *     *     *     *

I would like it to look like this:

Any seat marked with an asterick is available.

Code:

    	 A     B     C     D     E     F
 Row 1   *     *     *     *     *     *
 Row 2   *     *     *     *     *     *
 Row 3   *     *     *     *     *     *
 Row 4   *     *     *     *     *     *
 Row 5   *     *     *     *     *     *
 Row 6   *     *     *     *     *     *
 Row 7   *     *     *     *     *     *
 Row 8   *     *     *     *     *     *
 Row 9   *     *     *     *     *     *
 Row 10  *     *     *     *     *     *
 Row 11  *     *     *     *     *     *
 Row 12  *     *     *     *     *     *
 Row 13  *     *     *     *     *     *

Any help or suggestions would be greatly appreciated!

Well you've only got a single line to add :-P

CPP / C++ / C Code:

for(row=0; row<rows; row++)
  {
    cout << "Row " << row << " "; // Can you tell me why this works?
    for(col=0; col<columns; col++)
      cout<<setw(5)<<seatChart[row][col]<<" ";
    cout<<endl; // I'll give you a hint... it's the same reason this line 
  }             //makes a new line after each row!

Thanks Aaron!

Yes, I see- it is very simple and I was trying to make it really hard. I went down the path of adding a column to the array and then changing from char to string.....then writing a statement for each cell in the first column. I appreciate your response!
