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!
