Question

What happens when more than two conditions are combined using the OR operator?

a.

The compiler produces multiple consecutive reversed conditions that skip the conditional block if satisfied and continue to the next condition if not satisfied

b.

The compiler produces multiple consecutive conditional jumps that go to the conditional block if satisfied and skip the conditional block if not satisfied

c.

The compiler produces multiple consecutive conditional jumps that go to the conditional block if all conditions are satisfied

d.

The compiler produces a single conditional jump that skips the conditional block if all conditions are satisfied

Posted under Reverse Engineering

Answer: (b).The compiler produces multiple consecutive conditional jumps that go to the conditional block if satisfied and skip the conditional block if not satisfied Explanation:When multiple OR operators are used, the compiler will produce multiple consecutive conditional jumps that each go to the conditional block if they are satisfied. The last condition will be reversed and will jump to the code right after the conditional block so that if the condition is met the jump won’t occur and execution will proceed to the conditional block that resides right after that last conditional jump.
