K&R Exercise 1.16 - Limitation on line length

Question

I\'m learning C from K&R\'s \"The C Programming Language\" book. I\'m doing the exercises specified in the book. I\'m on exercise number 1.16, but I don\'t understand it

Answer 1

    #include

    main()
    {
       long tlength = 0;
       short input, llength = 1;
       while (llength > 0)  {
          llength = 0;
          while ((input = getchar()) != EOF) {
              ++llength;
              if (input == '\n')
              break;
          }
          tlength = tlength + llength;
          printf("\nLength of just above line : %5d\n\n", llength);
       }
       printf("\n\tLength of entire text : %8ld\n", tlength);
       return 0;
    }

According to me, This question only wants the length of each arbitrarily line + At last the length of entire text.

Try to run this code and tell me is it correct according to question because i too confuse in this problem.
