I personally prefer using VCs - BUT - what do people think about the way
questions are worded, e.g. 99p7q2: "Give a detailed proof using Floyd-Hoare
logic that... " - does that exclude the use of VCs? His model answer online
is a proof with inference rules, do you think using VCs in that question
isn't quite what is being asked for?
