For the reliable source, you can take a look at operator overloading, or, better, section 13.5.1 [over.unary] in the standard C++: A prefix unary operator shall be implemented by a non-static member function (9.3) with no parameters or a non-member function with one parameter. Thus, for any prefix unary operator @, @x can be interpreted as ...

Chapter 14 Overloaded Operators - Modelica

A binary and/or unary operator-class may only contain functions that are allowed for this binary and/or unary operator-class; and in case of '-' it is the union of these sets, since it may define both a unary (negation) and binary (subtraction) operator.

Important Points: The Modulo operator (%) operator should only be used with integers. Other operators can also be used with floating point values. ++a and a++, both are increment operators, however, both are slightly different.In ++a, the value of the variable is incremented first and then it is used in the program.In b--, the value of the variable is assigned first and then it is incremented.

Function Overloading in C++ - GeeksforGeeks

C++ function overloading allows you to define multiple functions with the same name but different parameters. It is a form of compile time polymorphism in which a function can perform different jobs based on the different parameters passed to it. It is a feature of object-oriented programming that increases the readability of the program. Example. Assume that you have to add 2 integers.

c++ - Are free operator->* overloads evil? - Stack Overflow

I was perusing section 13.5 after refuting the notion that built-in operators do not participate in overload resolution, and noticed that there is no section on operator->*.It is just a generic binary operator. Its brethren, operator->, operator*, and operator[], are all required to be non-static member functions.This precludes definition of a free function overload to an operator commonly ...
