Let’s debug! 

Specifically we will move the value of inside the constant integer of 10 decimal into ECX.

We open GDB in quiet mode and break on _start and run by following the commands above.

As we can see when we info registers the value of ECX is 0.

After we step into twice, we now see the value of ECX as 10 decimal of 0xa hex.

I look forward to seeing you all next week when we dive into hacking our third assembly program!
