char * find;
ret_val = fgets(st, n, stdin);
if (ret_val)

   find = strchr(st, '\n'); // look for newline
   if (find) // if the address is not NULL,
      *find = '\0'; // place a null character there
   else

     while (getchar() != '\n')

I am trying to store titled notes about many subjects
but I have problem with the reading function and may be
also the order of the conditional & looping control statments
I hope someone can help.
