Need correct Answer

Create a DWORD array named 'z' of size 3 using DUP operator. Leave the array 'z' uninitialized.
You can denote the items in the array as [Zo, Z1, Zz], where zo is the first item, z, is the second item,
z is the third item
Update each array item using the following expressions.
Zo = x + 130
21 = y +x - zo
Z2 =r+x- 13
- Where x, y, r are I16-bit integer memory variables.
- x = 10, y = 15, r= 4
- Use mov, movzx, movsx, add, sub instructions only.
(hint: Do not alter the value of x, y and r during the computation. Transfer them to appropriate registers to do
computation)
- At the end, open memory window to see the variable z stored in memory (little endian format).
If you code correctly, zo = 140 in decimal, z, = -115 in decimal, z, = 1 in decimal
Use the debugger to verify your answer.
