(A) 10
(B) 11
(C) Infinite
(D) The program will show compile-time error


Answer: (B)

Explanation: In for loop, mentioning expression is optional. >>= is a composite operator. It shifts the binary representation of the value by 1 to the right and assigns the resulting value to the same variable. The for loop is executed until value of variable i doesn’t drop to 0.
