What is the difference between the hexadecimal number '\ 0x' and '\ x?

The difference is not big. The numbers are all output in hexadecimal notation.

\ 0x: when the number of outputs is converted to hexadecimal with only one digit, add 0 in front, for example, 0a. Other outputs are output according to actual conditions.
\ X: Convert the number of outputs to the actual number of digits in hexadecimal format.

In addition, there is a difference between lowercase X and uppercase X. lowercase x outputs The hexadecimal notation, while uppercase x outputs the uppercase notation (mainly for abcdef)
