$($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 $10\mathrm{.}12$ and unpacks it into four characters. To unpack characters from a four$-$byte unsigned int, combine the unsigned int with the mask $4278190080(11111111000000000000000000000000)$ and right shift the result $8$ bits. Assign the resulting value to a char variable. Then combine the unsigned int with the mask $16711680(00000000111111110000000000000000).$ 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.
