Unsigned char a a 65535

Web3) Another difference between char and byte is that char is a larger data type than a byte. The range of byte is between -128 to 127 but the range of char is from 0 to 65535 because a byte is a signed 8-bit data type and char is an unsigned 16-bit data type hence, its maximum value is 2 ^ 16 - 1 which is 65535.
