Consider the following code.

struct as$\_$struct $\{$ uint$8\_$t first; uint$8\_$t second; uint$16\_$t third;

$\}$;

union as$\_$union $\{$ uint$16\_$t first; uint$8\_$t second; uint$32\_$t third;

$\}$;

int main$($void$)\{$

void $*$void$\_$ptr $=$ malloc$(4)$;

uint$32\_$t $*$ptr$32=($uint$32\_$t $*)$void$\_$ptr;

$*$ptr$32=0$xFACEB$00$C;

struct as$\_$struct $*$as $=($struct as$\_$struct $*)$void$\_$ptr; union as$\_$union $*$au $=($union as$\_$union $*)$void$\_$ptr;
