Recall that an opaque predicate is a "conditional" that is actually not a conditional. That is, the conditional always evaluates to the same result, but it is not obvious that this is the case.

a. Why is an opaque predicate a useful defense against reverse engineering attacks?

b. Give an example—different from that given in the text—of an opaque predicate based on a mathematical identity.

c. Give an example of an opaque predicate based on an input string.
