1. Before you compile and run it, predict the values it will print. All non-blank predictions are correct.

(1 point each, total 10 points)

Size(char) = __________

Size(short) = __________

Size(int) = __________

Size(long) = __________

Size(long long) = __________

Size(void *) = __________

Size(s1_t) = __________

Size(s2_t) = __________

s3.vals[0] = __________

s4.vals[0] = __________

2. Now, type it (given c code) in, compile and run it on a fox machine OR personal machine AND rextester.com. Fill in the results here.
