Hello developers, right now it is Summer here and nature is blooming and beckoning us to leave the warm glow of our computers behind. During those moments where you’ve hopefully got some time in the sunshine to relax, we’ve got some great new C++ topics for you to peruse. Today we have 5 more C++ posts about Copy Assignment Operators. All of the C++ examples in these posts can be used with C++ Builder Enterprise, Architect, Professional Editions, or the free version C++ Builder 11 CE. These examples can be used in Console applications, in VCL Windows applications, or in Multi-Device Firemonkey (FMX) applications on Windows, iOS, and Android.

Here, our standard C++ examples can also be used with Dev-C++, BCC C++ Compilers, and some other compilers such as the GCC compiler. If you are 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 recently released. 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.

Where can I learn Modern C++ with a free C++ compiler?

If you don’t know anything about C++ or the C++ Builder IDE, don’t worry, we have a lot of great examples on the LearnCPlusPlus.org website and they’re all completely free. Just visit this site and copy and paste any examples there into a new Console, VCL, or FMX project, depending on the type of post. We keep adding more C and C++ posts with sample code. In today’s round-up of recent posts on LearnCPlusPlus.org, we have new articles with very simple examples that can be used with:

Read the FAQ notes on the CE license and then simply fill out the form to download C++ Builder 11 CE.

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).

How to use a copy assignment operator in modern C++ with C++ Builder CE?

In 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. A copy assignment operator is used with the “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. One of the copy assignment operator kinds is the Eligible Copy Assignment Operator. It is ‘eligible’ if this default operator or user defined copy assignment operator is not deleted. In the first post, we explain What an eligible copy assignment operator is in C++. https://learncplusplus.org/what-is-an-eligible-copy-assignment-operator-in-c/

The implicitly-defined copy assignment operator is defined If neither deleted nor trivial. That means this operator has a function body which is generated and compiled. This is called an implicitly-defined copy assignment operator. This operator can be deleted, then this is called a deleted implicitly-defined copy assignment operator or we say that the implicitly-defined copy assignment operator is deleted. In the next post, we explain about deleted implicitly-declared copy assignment operators in C++ examples. https://learncplusplus.org/what-is-deleted-implicitly-declared-copy-assignment-operator-in-c/

We describe and explain the implicitly-defined copy assignment operator in C++ in this article https://learncplusplus.org/what-is-an-implicitly-defined-copy-assignment-operator-in-c/

This default copy assignment operator is declared automatically in a new class declaration, it is implicitly-defined or defaulted copy assignment operator and also a trivial copy assignment operator. In the next post pick, we explain answer the question “what is a trivial copy assignment operator in C++”. https://learncplusplus.org/what-is-a-trivial-copy-assignment-operator-in-c/

I promise it’s all easier than it sounds!

What does uppercase T mean in C++?

Knowing the correct syntax for any command, function or method is really important in C++ before you can write code effectively. Generally, we need to learn what kind of return type or parameters are used. We can use the helpful features of our IDE such as auto completion to make things easier, or we check online syntax examples. In modern C++ programming, sometimes we see an uppercase T in syntax definitions. You might already know that this T means it is a type, a function template, but what does it mean in reality? What do we mean by T in C++? In this post, we explain what this uppercase T in C++ syntax means. https://learncplusplus.org/what-is-uppercase-t-in-c-syntax/

How to learn modern C++ for free with examples?

LearnCPlusPlus.org has been producing articles full of educational information about C and modern C++ daily that can be used with C++ Builder, C++ Builder CE, Dev-C++, BCC Compiler and some other compilers such as the GCC compiler. Here is a round-up of a few articles for today.

We like to hear your feedback. You motivate us so much with your likes and comments on social media (find us on Facebook, LinkedIn, Reddit, Twitter and all over) and here on the blogs too. Thank you for your valuable comments and questions. All of them help improve the quality of our future posts and new code examples.

We have a lot of unique posts waiting to come. We keep adding new topics every week about C++ in general and specific topics for C++ Builder, Dev-C++, and for the other C++ compilers. Please keep following our LearnCPlusPlus.org website for the latest posts and updates. Feel free to comment and share with your colleagues, students, members – knowledge is power, and knowledge shared is empowering.

What might be next for C++ Builder?

According to David Millington’s post, C++ Builder is aiming to include some amazing features; CLANG v15, support for C++20 and a lot of C++23 features, Win64 primary OS, new code completion, Visual Assist C++ navigation and refactoring, and lots more.

Disclaimer: All new features and improvements discussed in posts regarding future versions of RAD Studio are not committed until completed, and GA released.

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.
