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. WebA char in C and C++ represents the smallest unit of memory the C program can address*.. CHAR_BIT in C and C++ represents the number of bits in a char.It must always be at least 8 due to other requirements on the char type. In practice on all modern general purpose computers it is exactly 8 but some historic or specialist systems may have higher values.
