Syntax:
</p>
<pre class="c code c++" style="font-family:monospace;"> return<span class="sy0">-</span>type class<span class="sy0">-</span>name<span class="sy0">::</span><span class="me2">operator</span><span class="co2">#(parameter-list) {</span>

return<span class="sy0">-</span>type operator<span class="co2">#(parameter-list) {</span>
...
<span class="br0">}</span></pre>
<p>
The operator keyword is used to overload operators. The sharp sign (#) listed
above in the syntax description represents the operator which will be
overloaded. If part of a class, the class-name should be specified. For unary
operators, parameter-list should be empty, and for binary operators, parameter-
list should contain the operand on the right side of the operator (the operand
on the left side is passed as this).
For the non-member operator overload function, the operand on the left side
should be passed as the first parameter and the operand on the right side
should be passed as the second parameter.
You cannot overload the #, ##, ., :, .*, or ? tokens.
