Final

1. Suppose that the following instructions are executed:

lea      esi, source

lea      edi, dest

cld

mov    ecx, 5

for6: lodsb

inc       al

stosb

loop    for6

endFor6

Assuming that 00417000 is the address loaded in ESI and 00417005 is loaded in EDI, what will be the values stored in ESI and EDI following the for loop?

What will be stored in ECX?

What will be stored in the destination string?

Question 2
