The organization of memory and processor is word $($int also takes $116-$bit word$)$

variable a has the value #a$0$c$0$

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

stack frame before subroutine B call #c$010$

address of subroutine B #$1021$

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

is shown after subroutine B is called by itself $($recursively$),$ at label point C$.$ Subroutine B is called

for the first time B$($a$-2)$; somewhere in the program from address #$1011.$ Label C has address

#$1050.$

regardless of the programming language, subroutine B has the form

$B($int i$)$;

$\{$

int $p=i+1$;

$C$:$,B(i-3)$;

The content of the cell at address #c$0$fb
