There is warning reported during compilation:

$ gcc crc.c 
crc.c: In function ‘main’:
crc.c:35:10: warning: format ‘%s’ expects argument of type ‘char *’, but argument 2 has type ‘unsigned char (*)[32]’ [-Wformat=]
   35 |  scanf("%s", &data);
      |         ~^   ~~~~~
      |          |   |
      |          |   unsigned char (*)[32]
      |          char *

The application fails:

$ ./a.out 
Enter the data

Ms. Narine, instead of “%s” I wrote “%u” for unsigned char *. I think I fixed the problem. Thank You
