I need to do the following in ARM assembly language
Goals:
Initialize register X, Y, and Z to zero.
Loop 10 times, each time adding 1 to register X.
If register X is even, add one to register Y.
If register X is divisible by 3, add one to register Z.
Result:
Register X at 10.
Register Y at 5.
Register Z at 3 or 4 (depending on how whether you count zero or not).
Here is what I have:
