Old school C programmer would make it into a calculus problem for clarity/proof of concept. Until accessed, a memory location & variable location can be expressed as an indefinate integral. Memory location access request implies definate integral. 1) evaluation value indefinate of integrand variables: "A" less than/equal to "B" less than/equal to "C" less than/equal to "D". Variable a is start of sequence. Variable D is end of sequence. 2) integrand variables D & A define the continuous range of PC group of bits 3) integrand variables C & B define the cohntinous range of 8 bit char 4) Accessing bits outside the integrand limits implies math equivalent of computer segfault. In order to not generate a segfault, only positive delta, and epsilon is 0 or 1. aka The "alignment request" implies that A MUST be equal to B; C less than or equal to D. K&R C short hand for above is anonymous union.[0] Physics / Mechanical Engineering center of gravity approach rotated 90 & implimented via punch card reader that doesn't skip cards much more interesting physical list processing visual than calculus number line (IMHO). Physical form bit to bulky to carry to/from class room. Fortunately, electrial engineering split the difference via 1/2 way point (45 degree angle). Computer scientests get the autonoma / semantic analysis difference. Software Engineers, by completing the circle with & with out a sigh of "e e e e e e ..."
