How operator overloading in C++ impacts on performance?

Question

I was given a question: how operator overloading in C++ impacts on performance?

I'm not pretty sure how to answer it. I fully understand the idea and how to overload operators in C++, but what about performance?

Operator overloading is nothing but syntactic sugar for a function or method call. Does that answer your question? — Daniel Frey, Jul 05 '14 at 17:20

Calling an overloaded operator is the same as calling any function in the object. If you mark the operator as inline, you get the same benefits (or lack thereof) as any other inline function.

Nothing complicated at all.
