What is the difference between function overloading and operator overloading?

Question

C++ / C#

What is the difference between function overloading and operator overloading?
And can you please give an example of function overloading.

Answer 1

No difference.
Operators are a special case of a function, only with signatures strictly defined and described in the standard and with a specific keyword operator. Well, the difference in usage is that, as a rule, the compiler inserts operator calls into the code itself, and the programmer explicitly calls the functions. From the point of view of the overload, there is no difference.
UPD: additionally see Evgeny Shatunov 's comment

Answer 2

There is no second definition.
