If you just need one or two boolean variables use something like char
which has only 8 bits usually. If you need whole arrays of boolean
variables you'll want to look into bit manipulation to adress each bit
individually or try out what the compiler does with bit fields.
I think http://en.wikipedia.org/wiki/Bit_field has a fairly good discussion.
