Pending questions

  1. Mismatch between conversion specifier and argument for printf. See print-typeX-as-typeY.c.
    1. The output of Part A is deterministic. As an exercise, try to explain / understand the output in terms of the IEEE 754 floating point format.
    2. The output of Part B is also deterministic. You should be able to explain / understand most of the output.
    3. The output of Part C appears to be non-deterministic. I am looking for an explanation why this is so.
  2. Why do large variable length arrays cause problems? See large-vlas.c above. Is this documented in the C standard or a limitation of gcc's implementation?
