This question is contributed by Aastha Anand.
(A) The value of A is 4
(B) The value of A is 5
(C) Compilation Error
(D) Runtime Error
Answer: (B)
Explanation: Value of A is replaced by -B, the value of B is replaced by -C which becomes -(-C) then the value of C is replaced by 5 which results to -(-5) which is equivalent to 5. So A is replaced by 5.
