Question $8$

The compiler automatically executes two steps behind a "for" loop:

$(1)$ ECxECx$-1$; $(2)$ to determine if ECx$=0.$ The following five lines of code are here to implement the two steps above. $($Assume there are FIVE iterations$)$

main PROC

examLoop:

clear ECX with ZERO

MOV ECX, $5$ ; initialize ECX with $5$

$$

$$ ECX ECX$-1$

$$ to determine if ECx$=0$

$q,$

$$ if not equal to $0,$ repeat four steps above

INVOKE ExitProcess, $0$

main ENDP

Which line of code should be in the line $8?$

ADD ECX, $1$

SUB ECX, $-1$

Both A and C are correct

DEC ECX

MOV $-1,$ ECX
