How much does the INC instruction in x86 assembly add?
<p>Does the INC command used on registers increments by 1 byte or by 4 bytes?</p>

<p>For example, first I set mov ecx,0 and then inc ecx.
what does ecx hold?</p>

<p>Example number 2: esi holds an address in memory.
What happens in this case?</p>

<p>I think that in the first case is 4 bytes and in the second its 1 byte (because memory), am I right?</p>
