$($a$)$ Use the bitwiseoperators towrite the following function:

u n s i g n e d s h o r t s w a p $\_$ b y t e s $($ u n s i g n e d s h o r t i $)$ ;

s w a p $\_$ b y te s should return the number that results from swapping the two bytes in i$.$

$($Short integers occupy two bytes on most computers.$)$ For example, if i has the value

$0$x$1234(0001001000110100$ in binary$),$ then swap b y t e s should return $0$x$3412$

$(0011010000010010$ in binary$).$ Test your function by writing a program that reads a num

ber in hexadecimal, then writes the number with its bytes swapped:

E n t e r a h e x a d e c im a l number $($up t o f o u r d i g i t s $)$ : $1234$

Number w i t h b y t e s swapped: $3412$

Hint: Use the $\%$hx conversion toread and write the hex numbers.

$($b$)$ Condense the swap b y t e s function so that its body is a single statement$]$
