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.
