Q$-$kxjqh$.$ In the initialization code below, both function foo$()$ and bar$()$ return a random int type number.

int x $=$ foo$()$;

int y $=$ bar$()$;

unsigned ux $=$ x;

unsigned uy $=$ y;

Assume on a $32-$bit architecture, please justify whether the following claim is always true:

$($Hints: x and y are both signed integers. ux and uy are unsigned integers cast from x and y$.)$

$($x $*$ x$)>=0.$ Is this true?

Question $2$ Answer
