When the header is included, the Boolean type is also accessible as bool . Standard logical operators &&, , ! can be used with the Boolean type in any combination. WebSome languages (like C/C++) provide ways of storing boolean values as single bits, if these bits are bundled in a single byte. In other words, in C, you can store eight booleans in a byte. But few ever use this since memory is cheap and processors manipulate data in 8/16/32/64 bit chunks. – Gort the Robot Jan 29, 2013 at 2:51 free phone # search
