sudoku

[jsfq]

I am trying to write a program that will help play Sudoku. It needs to read in the data from a txt file using a get. And follow the letter commands N= new game, A= add character, R= remove d= display board. What I am having difficulty with at the moment is reading the board into a 2d array board. After N it should read in the next characters including the blanks into an array. I can't seem to get the right numbers in the right format. The input will be attached below thanks for any help

  #include<iostream>
#include<fstream>
#include<iomanip>
using namespace std;
const int MAXCOL = 9;
const int MAXROW = 9;

void dis_board(char arr[][MAXCOL]);
void new_board(char arr[][MAXCOL], char ch, ifstream& in);
int main()
{
	char board[MAXROW][MAXCOL];
	int row, col, num_ele = 0, num1;
	char ch1;
	ifstream infile;
	infile.open("mp6in.txt");

	infile.get(ch1);
	while (infile)
	{
		
		if (ch1 == 'N')
		infile.ignore(10, '\n');
		infile.get(ch1);


			
		
			new_board(board, ch1, infile);

		//dis_board(board);
		
		infile.get(ch1);
	}
	dis_board(board);
}
void dis_board(char arr[][MAXCOL])
{
	for (int i = 0; i < MAXROW; i++)
	{
		for (int j = 0; j < MAXCOL; j++)
		    cout << arr[i][j] << " ";
		    cout << endl;
    }
}
void new_board(char arr[][MAXCOL],char ch, ifstream& in)
{
	for (int i = 0; i < MAXROW; i++)
	{
		for (int j = 0; j < MAXCOL; j++)
		{
			in >> (arr[i][j]);
		}
	}
}

What is the purpose of line 24? It reads the first character of the new sudoku board so the new_board will start reading from the second character (the 4).
