5/5, but I don't think this test is very good at capturing the more obscure features of C, they all just deal with the fact that platforms have different datatypes/alignment requirements, except for the last one. I think a better example would be the following: int a=1, b=2, i, j; i = a += 2, a + b; j = (a += 2, a + b); Whats the value of a, b, i, j? Hint: i and j are different. Which begs the question, why does C have those features in the first place? The only C code where it's reasonably common seems to be in crypto algorithms.
