    Angry Need Help with Bitwise actions!


    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...

    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 ;)
