read data from a file

when reading data from the attached file, apart from the four corner which only associated with #s, how to only grap the data inside the 4 #s border, which are numbers 0-9 and some #s in the middle and store them into 2d array? i only want to store the numbers and the #s between the numbers inside. there is a space in between numbers and #s. there are some spaces, new line character at top, bottom, left and right of the square. below are the codes that i implemented but kind of stuck in some way as may need your help to carry on.

Code:

#include <stdio.h>
#include <stdlib.h>
#include <stdbool.h>
#include <math.h>

#define row 12      /* Number of rows on square */
#define col 12      /* Number of columns on square */

int square[row][col];
int i = 0, j = 0, ch;

int main(int argc, char *argv[]) {
    
    while ((ch = getchar()) != EOF) {
          if (ch >= 0 || ch <= 9) {
             for (i = row; i >= 1; i--) {
                 for (j = ch; j <= 23; j++) {

thanks in advance.

I can't understand what you want correctly.But i noticed a bug in your code
getchar() returns a char value but you are trying to store it in a int variable.
I you can explain more the problem I think i can help you

Thanks
