Am i filling this array wrong or outputting it wrong?

Question

I am working on a program that fills an array with data from a text file. When I output the array its contents are not in the order I thought I read them in. I'm thinking the problem is either in one of the for loops that inputs data into the array or outputs the array to the iostream. Can anyone spot my mistake?

The data:

(I changed the first number in each row to 2-31 to differentiate it from the 0's and 1's)

The output:

The code:

#include <cstdlib>
#include <iostream>
#include <fstream>
#include <iomanip>

using namespace std;

int main()
{
    ifstream inFile;
    int FC_Row, FC_Col, EconRow, EconCol, seat, a, b;

    inFile.open("Airplane.txt");

    inFile >> FC_Row >> FC_Col >> EconRow >> EconCol;

    int airplane[100][6];

    int CurRow = 0;
    int CurCol = 0;

    while ( (inFile >> seat) && (CurRow < FC_Row)) 
    {
     airplane[CurRow][CurCol] = seat;
     ++CurCol;
      if (CurCol == FC_Col)
       {
       ++CurRow;
       CurCol = 0;
       }
    }


while ( (inFile >> seat) && (CurRow < EconRow)) 
{
 airplane[CurRow][CurCol] = seat;
 ++CurCol;
  if (CurCol == EconCol)
    {
     ++CurRow;
     CurCol = 0;
    }
 }

    cout << setw(11)<< "A" << setw(6) << "B"
    << setw(6) << "C" << setw(6) << "D"
    << setw(6) << "E" << setw(6) << "F" << endl;
    cout << " " << endl;

    cout << setw(21) << "First Class" << endl;
    for (a = 0; a < FC_Row; a++)
    {
        cout << "Row " << setw(2) << a + 1;
        for (b = 0; b < FC_Col; b++)
        cout << setw(5) << airplane[a][b] << " ";

        cout << endl;
    }

    cout << setw(23) << "Economy Class" << endl;
    for (a = 6; a < EconRow; a++)
    {
        cout <<"Row " << setw(2)<< a + 1;
        for (b = 0; b < EconCol; b++)
        cout << setw(5) << airplane[a][b] << " ";

        cout << endl;
    }


    system("PAUSE");
    return EXIT_SUCCESS;
}

Answer 1

You're filling it wrong.

for (a = 0; a < 100; a++)    
    for (b = 0; b < 6; b++)

The above loop doesn't match up very well with the first lines of your file, where you don't have 6 elements per row.

In the first inner loop, you will read 2, 1, 1, 1, 3, 0 into airplane[0].

EDIT: The fix.

for (a = 0; a < FC_Row; a++)    
    for (b = 0; b < FC_Col; b++)
        inFile >> airplane[a][b] ;

for (a = 0; a < EconRow; a++)    
    for (b = 0; b < EconCol; b++)
        inFile >> airplane[a+FC_Row][b] ;

Answer 2

Your code that fills the array:

   for (a = 0; a < 100; a++)    
        for (b = 0; b < 6; b++)
            inFile >> airplane[a][b] ;

assumes that there are 6 columns in every row, there aren't, there are only 4 rows in the first 6 rows.
