C++ Overloading the + operator results in error
<p>I have tried to overload the "+" operator for my class:</p>

<pre><code>Vector operator+( const Vector&amp; a, const Vector&amp; b );
</code></pre>

<p>However,it tells me:</p>

<pre><code>vector.h(12): error C2804: binary 'operator +' has too many parameters
</code></pre>

<p>I really don't get it. Please help me</p>
