    Querying the status of a bit (via bit-masking)

    Once you know how to query the status of a bit, it's not too difficult to iterate through all the bits you have. You can use shift operators to determine which bit you want to mask.

    mask = 1 << bit_number; // shift 1 over to which ever bit you want to mask
