WebThe C++ language gives the programmer the impression that memory is laid out as a sequence of something C++ calls “bytes.”. Each of these things that the C++ language calls a byte has at least 8 bits, but might have more than 8 bits. The C++ language guarantees that a char* ( char pointers) can address individual bytes.
