C++ Xcode OOP Friend Overload Tutorial
Our C++ Xcode OOP Friend (Operator) Overloading Tutorial presented here builds off the previous C++ Xcode OOP Multiple Inheritance Tutorial as shown below.
You can use friend functions to access private data members, which can be used when writing tailored input and output (I/O) coding in C++ for your class object (reporting) functionality. Today we write a friend operator overloading scenario for both input and output of our Colour class, which has three data members, the Red, Green and Blue integer colour component parts, commonly referred to as (R,G,B) when you’re talking in colour circles … man.
In object-oriented programming, operator overloading—less commonly known as operator ad-hoc polymorphism—is a specific case of polymorphism, where different operators have different implementations depending on their arguments. Operator overloading is generally defined by the language, the programmer, or both.
Operator overloading is claimed to be useful because it allows the developer to program using notation “closer to the target domain”[1] and allows user-defined types a similar level of syntactic support as types built into the language.

The link here was very useful … thanks a lot.

Here is a programming tutorial that introduces you to some more aspects of OOP … oops, forgot to say what OOP stands for … Object Oriented Programming … specifically regarding Multiple Inheritance.
Object-oriented programming (OOP) is a programming paradigm that represents concepts as “objects” that have data fields (attributes that describe the object) and associated procedures known as methods. Objects, which are usually instances of classes, are used to interact with one another to design applications and computer programs.
To me, the beauty of OOP is that it can relate to the nouns in our life. Think of an object that you can touch, like a wristwatch … it has features like its type of design, its size, its weight (ie. its properties), and it has objects that go to make it up, like cogs and wheels (ie. its components), and it has its related classes of objects like clock, alarm clock, oven timer etcetera (ie. its characteristics), and its more fundamental essence, the class of watch (ie. its inheritance).
In this tutorial we touch on Multiple Inheritance by the way one class can inherit from more than one other class.
