8-12. (integer) Bit operation. write a program. After the user gives the start and end numbers, the following table is displayed, showing the decimal, binary, octal, and hexadecimal representation of all integers between the two numbers. if the character is printable ASCII, print it out. If none is printable, the header in the ASCII column is omitted.
