"...without the use of a computer." And in this age, with technology so advanced, and computing resources so inexpensive ... why? Because it's the geek's athletic challenge? Whomever's brain holds the most memorized facts is the smartest brain in the world? I'd guess someone would answer "because you need to know this stuff to be good at your programming job!" To which I reply: if you ever make the assumption that you know how some bit of code will work in a system, you're well on your way to becoming the infallible coder that no one likes to work with. This is why we have testing methodologies. Yes, you need to be aware of this particular nuance of C. My answers were more high-level ("the address of the beginning of the array", "the next int in memory, not the next byte", etc) and I have no need to know the precise memory locations when I can ask the computer to tell me.
