A lot of this stems from trying to insist that char just means "small" and not "8 bits" and that int means "bigger than that" and not "32 bits". In fairness, K&R dealt with an era where 9 bit architectures existed, but char is 8 bits now. Everywhere.

In the world of microcontrollers, CHAR_BIT can be 16 or some other funky number. char is usually 8 bits in size, though.
