Question

Suppose that you are given the following partial data segment, which starts at address 0x0700 : .data idArray DWORD 1800, 1719, 1638, 1557, 1476, 1395, 1314, 1233, 1152, 1071, 990 u DWORD LENGTHOF idArray v DWORD SIZEOF idArray What value does EAX contain after the following code has executed? (Ignore the .0000 that Canvas sticks on the end) mov esi, OFFSET idArray mov eax, [esi+0*TYPE idArray]

Answer 1

Answer:

The value EAX contain after the code has been executed is 1233

Explanation:

Solution

Now,

The below instruction describes the MOV operation.

The MOV esi, OFFSET idArray .

It shows the movement, the offset value of the idArray in the esi.

Thus,

Follow the below instruction

MOV eax, [esi+7*TYPE idArray]

It will move the address of the idArray at that position into eax.

Value at the 7th position is moved to eax.

Therefore, the value at eax will be 1233.
