1. How do I verify that the input is not an integer? A. Please see Tutorial 2 P. 29 2. Is 1.0 legal integer? A. No 3. Is -998 legal integer? A. Yes 4. NEWS - Version 3 was uploaded. Fixes are marked in green 5. How will scanf behave if .... and how to detect .... in case of keyboard input and/or redirection? A. The suggestion to use fseek WAS REMOVED. Scanf is a tricky function and many questions about it arise every semester. You will have to play with it a little and see how it behaves in different situations. There is probably no way around that. In redirection, the fseek command suggested in previous HW3 versions clears the whole redirected input, thus causing different behavior from keyboard input. Please read the updated HW3 instructions what to do if scanf returned -1 (end of input), and other cases. 6.
