The organization of memory and processor is word$-$base $($int also takes one $16-$bit

word$)$

variable a has the value #$a0co$

top of the stack $($full descending$)$ #c$100$

stack frame before calling subroutine A #c$105$

address of subroutine $A$ #$1001$

Calling rules: $C$ convention, no static link, function result passed in registers. The stack

is shown after subroutine $A$ is called, at label point $C.$ Subroutine $A$ is called

$1,a+1$; from address #$1050.$

Regardless of the programming language, subroutine A has the form:

int $x,y,z$;

$\{$

int $q=x+020$

$C$:dots

$\}$

Specify, in hexadecimal, what value the cell with the address #c$0$ff will contain.
