Chapter 10, Problem 10.13E

(Unpacking Characters from an Integer) Using the right-shift operator, the bitwise AND operator and a mask, write function unpackcharacters that takes the unsigned int from Exercise 10.12 and unpacks it into four characters. To unpack characters from a four-byte unsigned int, combine the unsigned int with the mask 427819 00 8 0 ( 11111111  0000000000000000   00000000 ) and right shift the result 8 bits. Assign the resulting value to a char variable. Then combine the unsigned int with the mask 1671168 0 ( 00000000  11111111 00000000   00000000 ) . Assign the result to another char variable. Continue this process with the masks 65280 and 255. The program should print the unsigned int in bits before it’s unpacked, then print the characters in bits to confirm that they were unpacked correctly.
