Q$1$ Fill in the blank entries in the following table, giving the decimal and hexadecimal representations of different powers of $2$:

n $2$n $($decimal$)2$n $($Hex$)$

$1010240$x$400$

$21........................................................$

$33........................................................$

$............................64............................$

$............................2048............................$

$........................................................0$x$2000000$

$........................................................0$x$8000000$

Q$2$ void show$\_$byte$($byte$\_$pointer start, int len$)$

$\{$

int i;

for$($i$=0$; i $8.$ For reference, we show the result of evaluating the expressions for x $=0$x$196$a$45$c$7,$ with w $=32.$

A$.$ The least significant byte of x$,$ with all other bits set to $0.[0$x$000000$c$7]$

B$.$ All but the least significant byte of x complemented, with the least significant byte left unchanged. $[0$xe$695$bac$7].$

C$.$ The least significant byte set to all ls$,$ and all other bytes of x left unchanged $[0$x$196$a$45$ff$].$
