WebThe C++ language does not include a data type that allows us to represent a single bit. Instead, we have to work with groups of bits. The smallest group of bits the language allows use to work with is the unsigned char, which is a group of 8 bits. C++ does include operators that allow us to manipulate the bits in a number. WebIn C++, these operators can be used with variables of any integer data type; the boolean operation is performed to all of the bits of each variable involved. For example, supposing two variables: a and b , both of type unsigned char , where a contains 195 (11000011 in binary) and b contains 87 (or 01010111 in binary).
