    Answer : Option C

    Explanation :

    In TurboC, the output will be 2, 1 because the size of the pointer is 2 bytes in 16-bit platform.

    But in Linux, the output will be 4, 1 because the size of the pointer is 4 bytes.

    This difference is due to the platform dependency of C compiler.
