Write a small program which prints the differences between all ten digit characters (from '1' to '0') and zero ('0'). Print each one on a separate line. Your program must print the same result as the expected output.

Example output:

'1' - '0' is: 1

'2' - '0' is: 2

'3' - '0' is: 3

'4' - '0' is: 4

'5' - '0' is: 5

'6' - '0' is: 6

'7' - '0' is: 7

'8' - '0' is: 8

'9' - '0' is: 9

'0' - '0' is: 0
