10.12 Packing Characters into an Integer) The left-shift operator can be used to pack four char- te a program that inputs four characters from the keyboard and passes them to function packCharacters. To pack four characters into an un sfgned int variable, assign the first character to the unsigned int variable, shift the unsigned int variable left by 8 bit positions and combine the unsigned variable with the second character using the bitwise inclusive OR operator. Repeat this process for the third and fourth characters. The pro gram should output the characters in their bit format before and after they're packed into the un- signed int to prove that the characters are in fact packed correctly in the unsigned int variable. Do not use global variables. If your scanf is not waiting for your input, it is because it consumed the Carriage Return from the buffer remained from the previous scan. This only happens if you use %c in the scant. To remove left over Carriage Return in the buffer, use getcharp; right after the scanf(%c"). Refer to "User Input. Explained" document for further explanation. Information about packCharacter function Should not print any output. Should accept one character and the target integer that will be used for packing. Should perfom the left shift and append the character to the target
