Hello everyone, I hope now you, your computer, and your development software are enjoying your summer vacation, or at least you’re happy with your work 🙂 Over on LearnCPlusPlus.org, we add new C++ posts every day. These are good to learn the features of modern C++ compilers. In this round-up of recent articles, we explain some features of C++11 that tend to tighten the rules, to detect some problems that often arise by the virtual overrides. To achieve this goal, C++11 introduced two new contextual keywords, the final and the override specifiers.

In this post we explain, what is the virtual function specifier, what is override specifier, what is the explicit virtual override specifier, and how to use the final and the override specifiers. In addition, we explain how the range-based for loop works in modern C++. We try to explain each topic by giving very simple C++ samples and by using more complete C++ examples to highlight modern way of programming.

Where can I learn 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:

• The free version of C++ Builder 11 CE Community Edition
• or a professional C++ Builder 
• or free BCC32C C++ Compiler and BCC32X C++ Compiler
• or the free Dev-C++

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

How to use modern C++ with C++ Builder?

In modern C++ software, a virtual function is a function in a base class or struct that can be redefined in derived classes or structs. They are member functions whose behavior can be overridden in derived classes. The virtual function specifier is the ‘virtual’ specifier to declare a virtual function in a base class. In the first post, we explain how we can use virtual function specifiers in modern C++.How to learn C++ for free using C++ Builder CE? https://learncplusplus.org/what-is-a-virtual-function-specifier-in-modern-c/

The for loops are one of the great features of C and C++ language that has many options to break, continue, or iterate in a loop. In modern C++, there is a range-based for loop that makes it simple to iterate through a variable type that has members (i.e. strings, lists, arrays, vectors, maps, etc.). The range-based for loop is a feature for the for() loops introduced by the C++11 standard and in the next post, we explain what is range-based for loop. https://learncplusplus.org/what-is-a-range-based-for-loop-in-modern-c/

Modern C++ has many additions compared to the original C++ standard. Regarding virtual overrides, C++11 tends to tighten the rules, to detect some problems that often arise. To achieve this goal C++11 introduces two new contextual keywords, the final and the override specifiers. The override specifier is used to redefine the base class function in a derived class with the same signature i.e. return type and parameters. In the next post, we explain an override specifier in modern C++. https://learncplusplus.org/learn-how-to-use-the-override-specifier-in-modern-c/

The override specifiers are used with a C++ compiler that is compatible with C++11 and the other higher C++ standards. In another post, we explain the explicit virtual override specifier in modern C++. https://learncplusplus.org/what-is-an-explicit-virtual-override-in-modern-c/

C++11 introduced two new contextual keywords, the final and the override. The final specifier (keyword) is used for a function or for a class that cannot be derived and overridden by derived classes. This final specifier is used with the C++ compiler that has C++11 and the other higher C++ standards. In the last post, we explain how to use the final specifier in modern C++. https://learncplusplus.org/learn-how-to-use-the-final-specifier-in-modern-c/

Thank you for your valuable comments and questions. All of them help improve the quality of our future posts and new code in these posts.

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 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).

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.

What’s Coming for C++Builder: An Amazing Preview

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.
