(Unpacking Characters from Unsigned Integers) Using the right-shift operator, the bitwise AND operator and a mask, write function unpackCharacters that takes the unsigned integer from Exercise 22.11 and unpacks it into two characters. To unpack two characters from an unsigned two- byte integer, combine the unsigned integer with the mask 65280 (11111111 00000000) and right- shift the result 8

bits. Assign the resulting value to a char variable. Then, combine the unsigned in- teger with the mask 255 (00000000 11111111). Assign the result to another char variable. The pro- gram should print the unsigned integer in bits before it’s unpacked, then print the characters in bits to confirm that they were unpacked correctly. What will be an ideal response?
