Hello C++ developers. This week, we continue our Copy Assignment Operator topics in C++. We have more posts in detail with examples. All of the C++ examples in these posts can be used with C++ Builder or the C++ Builder 11 CE Community Edition. These examples can also be used with Dev-C++, BCC C++ Compilers, and some other compilers such as the GCC compiler. If you just starting out on your C++ journey and want to jump to a modern IDE and C++ compiler, there is a free version of C++ Builder, C++ Builder 11 CE Community Edition released on April 2023. If you are a start-up developer, student, hobbyist, or just interested in learning to code then the C++ Builder Community Edition may well be just the thing for you.

What is a copy assignment operator in modern C++?
Object-Oriented Programming (OOP) is a method of mapping real-world objects and data to computer functions and data structures. Classes and Objects are part of object-oriented methods and typically provide features such as properties and methods. One of the features of an OOP Editor is a copy assignment operator that is used with “operator=” to create a new object from an existing one.
The Copy Assignment Operator in a class is a non-template non-static member function that is declared with the “operator=“. This operator allows you to copy objects of classes, structs, and unions. When you create a class or a type that is copy assignable (that you can copy with the = operator symbol), it must have a public copy assignment operator. In the first post, we explain the use of a forced default copy assignment operator with C++ examples. https://learncplusplus.org/what-is-a-forced-default-copy-assignment-operator-in-modern-c/
The declaration and definition of a class are different terms in C++ language. In the next post, we explain what the declaration and definition are and what we mean by an implicitly declared copy assignment operator in C++ along with some examples. https://learncplusplus.org/what-is-implicitly-declared-copy-assignment-operator-in-c/
In C++, the Copy Assignment operator is the default in any class declaration, and it is automatically declared. This is also called the forced copy assignment operator which is default in any class declarations. This means, if you don’t want this default feature, you should delete it by using the delete option as given in the syntax above. In the next post, we explain what we mean by “avoiding implicit copy assignment operator”, and how can we use the delete option with copy assignment in C++ examples. https://learncplusplus.org/what-is-avoiding-implicit-copy-assignment-in-c/

What is new in C++ Builder CE?
C++ Builder 11 CE which is the free Edition of C++ Builder has been recently released. Embarcadero has made available a Community Edition license for the most recent 11.3 release of Delphi and C++Builder. This is a free edition of either Delphi or C++Builder for students, hobbyists, and startups (as the license is revenue-limited).
Note that Embarcadero announced the release of RAD Studio 11 Alexandria Release 3, also known as RAD Studio 11.3, along with Delphi 11.3 and C++Builder 11.3. This release is focused on quality and improvements, building on the great new features in RAD Studio 11 Alexandria three previous releases.
C++ Builder is the easiest and fastest C and C++ IDE for building simple or professional applications on the Windows, MacOS, iOS & Android operating systems. It is also easy for beginners to learn with its wide range of samples, tutorials, help files, and LSP support for code. RAD Studio’s C++ Builder version comes with the award-winning VCL framework for high-performance native Windows apps and the powerful FireMonkey (FMX) framework for cross-platform UIs.
There is a free C++ Builder Community Edition for students, beginners, and startups; it can be downloaded from here. For professional developers, there are Professional, Architect, or Enterprise version.
