Answer from cs61c-el (David Tung 16479725) for Question 2
Technically, I do not think that it should have any real noticeable effect on the C programmer.  After all, it would be the responsibility of the compiler to take care of the issues of the assembler and the linker, so the actual implementation should be hidden.  Perhpas the C programmer would have to worry about issues of including library files or managing memory, but it seems unlikely.
