    copied!<p>I know I can answer this question easily for myself by generatin the code and see if it compiles. But since I couldn't find a similar question, I thought it's knowledge worth sharing. Say I am overloading the + operator for MyClass. Can I overload it multiple times. Different overload for different types. Like this:</p> <pre><code>class MyClass{ ... inline const MyClass operator+(const MyClass &amp;addend) const { cout&lt;&lt;"Adding MyClass+MyClass"&lt;&lt;endl; ...//Code for adding MyClass with MyClass } inline const MyClass operator+(const int &amp;addend) const { cout&lt;&lt;"Adding MyClass+int"&lt;&lt;endl; ...//Code for adding MyClass with int } ... }; int main(){ MyClass c1; MyClass c2; MyClass c3 = c1 + c2; MyClass c4 = c1 + 5; } /*Output should be: Adding MyClass+MyClass Adding MyClass+in*/ </code></pre> <p>The reason I want to do this is that I am building a class that I want to be as optimized as possible. Performance is the biggest concern for me here. So casting and using switch case inside the operator + overloaded function is not an option. I f you'll notice, I made both the overloads inline. Let's assume for a second that the compiler indeed inlines my overloads, then it is predetermined at compile time which code will run, and I save the call to a function (by inlining) + a complicated switch case scenario (in reality, there will be 5+ overloads for + operator), but am still able to write easily read code using basic arithmetic operators. So, will I get the desired behavior?</p>
