In a 16 Bit C compiler we have 2 bytes to store an integer, and 1 byte for a character. For unsigned integers the range is 0 to 65535. For signed integers the range is -32768 to 32767. For unsigned character, 0 to 255. According to the integer type, shouldn't the signed character range be like -128 to 127. But why -127 to 127? What about the remaining one bit?
