Found a bug one minute after I did send my little program. :-)
There should be an else statement in the code. This code below
should work better (I hope). Probably there's more to fix, and
if you get strange results, then let me know and I'll fix it.

#include <stdio.h>

int main(int argc, char **argv)
{
  FILE *f;
  char c;
  int row;
  int row_chars;

  if(argc != 2)
  {
    printf("Usage: %s count_chars_for_each_row_in_this_file\n", argv[0]);
    return 1;
  }

  if((f = fopen(argv[1], "r")) == NULL)
  {
    printf("File %s not found.\n", argv[1]);
    return 1;
  }

  row = 1;
  row_chars = 0;
  while((c = getc(f)) != EOF)
  {
    if(c == '\n')
    {
      printf("Row: %d / Number of chars: %d\n", row, row_chars);
      row++;
      row_chars = 0;
    }
    else
      row_chars++;
  }
  fclose(f);
  return 0;
}

Sorry about this, and good luck using it!

Best regards,
Paul
