Thread: storing a pattern of characters into a 2D array

hello,

i am tinkering with some code that stores a pattern of characters into an array of 20x60, found from the standard input stream (basically a text file with characters on eachline 20x60 at the end of each line is a line break). i cannot get the program to print the text file when i execute and redirect a text file to the executable. can anyone help me out or let me know of some suggestions in the code i can make?

thanks!

Code:

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

#define    ROWS    20
#define    COLS    60

int main()
{
  int i, j, r, c;   // indexers
  char cell[ROWS][COLS];   // the pattern
  char value; // from input stream

  for( r = 0; r < ROWS; ++r)
  {
    c = 0;
    while( (value = getchar() ) != '\n')
    { 
      cell[r][c++] = value;    // store X or O
    }
  }
  
  putchar('\n');
  
  for( i = 0; i < ROWS; ++i )
  {
    for( j = 0; j < COLS; ++j )
      putchar(cell[i][j]);
    putchar('\n');
  }
  putchar('\n');

  return 0;
}
