in c++, this is a pointer but why we can use this.xxx to represent a member, not this->xxx
<p>in <code>c++</code>, <code>this</code> is a pointer but why we can use <code>this.xxx</code> to represent a member, not <code>this-&gt;xxx</code>?
<code>this-&gt;xxx</code> should be the right one,
but why is <code>this.xxx</code> also OK?</p>
