    Angry Need Help with Bitwise actions!

    Hi

    I have an exam in C tomorrow, and Im completley lost when it comes to bitwise manipulation. Yes, I am a begginer.

    The question goes like this:
    I need to write a program that will recevie an order of Pizza. The order includes up to 8 extras,
    I need to save the order in one character and then print it for confirmation.

    I understand that I need to "Or it with 1" whenever an extra is chosen, but I do not know how to retreive the extra combination chosen.

    Please help!

    That doesn't look that hard. You can also use a mask of
    1000000 00000000 00000000 00000000

    and just store it either as one or zero as you move along the bits by shifting...

    >>> I have an exam in C tomorrow

    and

    >>> I am a begginer

    Surely, to do an exam in something pre requires that you have completed a course... and done your coursework... doesn't it?

    There was a fairly detailed thread about bitwise operators just last month. Do a forum seach and you might just pass your exam ;)
