Hello C++ developers, last week we had Coding Bootcamp 2023 by Embarcadero, and Summer Code Fest 2023 by Whole Tomato, and even in heavy weeks like that, Ian Barker still kindly reviews my posts as we both try to keep adding new articles for you. Our educational LearnCPlusPlus.org web page is growing thanks to you, and we have many new readers, thanks to your support. The site features posts which are great to learn the features of modern C++ compilers with very simple explanations and examples. In this round-up of recent articles, we explain the multi-threading features of modern C++ along with other useful methods for developers. In modern C++, multi-thread operations have evolved amazingly since C++11, and still, there are new improvements in the latest standards to enhance multi-thread operations further. The Concurrency Support Library is designed to solve problems that arise with multi-thread operations and this week we have some examples of multi-threading in C++. We explain the very useful multi-threading class std::thread with very simple examples that everyone can use with their functions, and we explain how we can use lambda expressions with std::thread in C++ with examples. C++11 adds atomic types and operations to the standard and we explain what is atomic type in C++. C++11 introduced new forms of literals using modified syntax and semantics to provide User-Defined Literals (UDL) also known as Extensible Literals and we explain how to use user-defined literals. C++11 standard improved the previous C99 standard feature __func__ and in the last post today we explain how to use user-defined literals.

How to use modern C++ with C++ Builder? In modern mathematics, physics, and computer science; optimized and faster app development in programming is very important to speed up computations. CPUs and GPUs are highly evolved by the number of cores and transistors to give more computational power to today’s servers and computers. Thus, we can use more cores and threads in our applications by using std::thread. We can use the std::thread class in multi-thread operations, and in the first post pick, we explain how to use std::thread and how can we use it with modern C++ examples. Lambda Expressions allow users to write an inline expression that can be used for short snippets of code that are not going to […]

Hello C++ developers, Yilmaz here from LearnCPlusPlus. RAD Studio’s C++ Builder, Delphi and their free community editions C++ Builder CE, and Delphi CE are a real force for modern application development. Our educational LearnCPlusPlus.org web page is another powerful element for learning details of modern C++ programming. It is growing well thanks to you, and we have many new readers, thanks to your support! The LearnCPlusPlus.org site has unique and new posts with examples suitable for everyone from beginners to professionals alike. The site features a plethora of posts which are great to learn the features of modern C++ compilers with very simple explanations and examples. In this round-up of recent articles, we explain atomics and atomics operations, which are the multi-threading features of modern C++ along with other useful methods for developers. You don’t have to be Robert Oppenheimer to get to grips with atomic operations in C++ so put away your safety googles and relax as we take you through the details. In modern C++, multi-thread operations have evolved amazingly since C++11, and still, there are new improvements in the latest standards to enhance multi-thread operations further. The concurrency support library in modern C++ is designed to solve problems in multi-thread operations. Since the C++11 standard, this library includes built-in support for threads (std::thread) with atomic operations (std::atomic).

Since the C++11 standard, this library includes built-in support for threads (std::thread) with atomic operations (std::atomic). C++11 adds atomic types and operations to the standard. Atomic types and operations provide a way of writing multi-threaded applications without using locks. In the next post, we explain what is std::atomic and how we can use atomic types efficiently in modern C++. Atomic types are special in multi-threading operations and they can be used to count things, to sum, and to calculate some data types. The fetch_add and the fetch_sub are atomic addition operations that atomically replaces the current value with the result of arithmetic addition or subtraction of the given value. […]

Hello everyone, Yilmaz here, from LearnCPlusPlus.org. Our educational LearnCPlusPlus.org web page is growing thanks to the support of you. We have many new readers, and we keep adding 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 modern C++ along with other beneficial methods for intermediate and professional developers. This week, we have C++ examples and an explanation about using non-copyable movable types in C++ templates. The rvalue references are important and we explain rvalue references to eliminate unnecessary copying in C++. C++11, C++17, and C++20 standards added to the richness of the language, and we explain one of these additions – explicit conversion operators. If you wonder what an explicit specifier is, we explain them in another post. C++11 introduced two new features: defaulted and deleted functions, we can use these two keywords to delete or to default methods in C++, and we explain this in the other two posts.

How to use modern C++ with C++ Builder? In C++, memory and CPU/GPU management are very important. Every declaration and usage of any items can cause a lot of heavy calculations, memory usage, and high CPU/GPU usage if used or manipulated unwisely. Using copy and move types in templates is very important when you develop a professional app. In the first post, we explain how you can use non-copyable movable types in C++ templates. https://learncplusplus.org/learn-how-to-use-non-copyable-movable-types-in-c-templates/ The rvalue references are a compound type like standard C++ references, which are referred to as lvalue references. New rvalue reference rules were set by the C++11 specifications. In many cases, data is copied that simply needs to be moved, that is, the original data holder need not retain the data. The rvalue reference can be used to distinguish cases that require copying versus cases that merely require moving data. In the next post, we explain how we use rvalue references to eliminate unnecessary copying in C++. https://learncplusplus.org/learn-how-to-eliminate-unnecessary-copying-in-c/ In modern C++, explicit-qualified conversion functions work in the same context as explicit-qualified constructors and produce diagnostics in the same contexts as constructors do. C++11, C++17, and C++20 standards have improvements in this explicit specifier. This is done to avoid situations when the compiler uncomplainingly accepts code […]

Hello everyone. With the C++11 standards, the move constructor allows you to move the resources from one object to another object without copying them. In this post we have gathered together some recent C++ articles from LearnCPlusPlus.org about Move Constructors. 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 Community Edition. 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 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 in 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.

How to use a move constructor in C++ with C++ Builder CE? The Move Constructor is one of the great features of Object Oriented Programming in C++. The move constructor allows you to move the resources from one object to another object without copying them. One of the move constructors is the Implicitly-defined Move Constructor which is defined or defaulted in a base class, and in the first post, we explain the Implicitly-defined Move Constructor in Modern C++. https://learncplusplus.org/what-is-an-implicitly-defined-move-constructor-in-modern-c/ Another move constructor is the Implicitly-declared Move Constructor, which is declared in a base class. In the next post we explain the implicitly-declared move constructor in Modern C++. https://learncplusplus.org/what-is-an-implicitly-declared-move-constructor-in-modern-c/ There is also an Eligible Move Constructor. In the next post, we explain an eligible move constructor in modern C++. https://learncplusplus.org/what-is-an-eligible-move-constructor-in-modern-c/ The other move constructor term is the Trivial Move Constructor which is defined or defaulted in a base class. We explain what a trivial move constructor in C++ is and how to use it. https://learncplusplus.org/what-is-a-trivial-move-constructor-in-modern-c/ Finally, the other move constructor is the Deleted Implicitly-declared Move Constructor (also it is shown in compiler errors as Implicitly-deleted Move Constructor) which is deleted in a base class directly or has been deleted because of some other declarations.

Hello C++ Developers, I hope now you are enjoying your summer vacation, or you are 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 cover some important features of C++ such as the friend declaration, the inline namespace, the extended sizeof function, the assignment operator, and the rules of C++ such as the Rule of Zero, the Rule of Three, the Rule of Five, and the Rule of Six. Some of these topics may not be necessary for beginners but they are important to understand as you progress on your coding journey. Table of Contents Where can I learn C++ with a free C++ compiler?

How to use a move constructor and copy assignment in C++ with C++ Builder CE? In C++ the standards have a wonderfully named extended friend declaration feature to address the class declarations which is a template parameter as a friend. This extended friend declaration is available with the C++ compiler that has C++11 and above standards. In the first post, we explain a friend and extended friend declaration in modern C++. https://learncplusplus.org/what-is-an-extended-friend-declaration-in-modern-c/ Namespaces are a kind of library or framework in C++. They are useful to hold the same name of classes, methods, and other entities in different namespaces. The C++11 standard and subsequent standards, allow the inline keyword in a namespace definition and in the next post, we explain how to use inline namespaces in modern C++. https://learncplusplus.org/what-is-the-inline-namespace-feature-in-modern-c/ Knowing the physical size of any data is very important in programming. While the programmers are trying to minimize data types or stream packages, the actual amount of global data transfer is increasing thanks to the demands of new technologies. To help combat this trend, we need to know each data type in programming. The sizeof() function is very useful to get the size of variables in bytes. C++11 extends the functionality of sizeof function so that class or class members can be sent as parameters even if no object has been instantiated. In another post, we explain with examples, what is the sizeof function, what is the extended sizeof() function, and how does C++11 extend the sizeof() operator on classes? https://learncplusplus.org/what-is-an-extended-sizeof-in-modern-c/ One of […]

Hello developers, actually there are no rules! ???? You have a broad freedom in C++. If your C++ app is running well and performing its functions well then, you’re doing good. For me, I think this is the main rule of developing applications, “develop C++ apps running perfectly that help people and the world“. In professional programming, you strive to create better applications that run perfectly and use memory, CPU, and GPU efficiently. But of course, joking apart, in reality, all computer programming languages actually do have rules; both those of syntax and those of semantics. This week we have more new C++ posts about some minor and major important rules of modern C++. If you are just starting out on your C++ journey and want to jump into the rules of modern C++, there is a free version of C++ Builder, C++ Builder 11 CE Community Edition released in 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. 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 Community Edition. Table of Contents How can we learn the rules of modern C++? Are there C++ examples of how to apply the rules of modern C++? What is new in C++ Builder CE? What might be next for C++ Builder? How can we learn the rules of modern C++? In modern C++, when you develop applications for future updates or upgrades to new compilers, and you want to use memory, CPU, GPU, and other peripherals of that device in a correct way, there are some recommendations in class definitions. In class definitions, there are some recommendations; called The Rule of Zero, Rule of Three, Rule of Five, and Rule of Six. In modern C++, there are some rules to support the principles of programming, one of which is the Rule of Six in C++ (also known as the Rule of Five, excluding the constructor). In the first post, we explain the Rule of Six in C++ that includes other the Rule of 5, the Rule of 3, and the Rule of 0. https://learncplusplus.org/what-is-the-rule-of-six-in-modern-c/ In the next post, we explain the Rule of Five in C++ (also known as the Rule of Six, including constructor) https://learncplusplus.org/what-is-the-rule-of-five-in-modern-c/ The Move Assignment Operator is one of the great features of Object-Oriented Programming in professional development. It complements features like the copy assignment operator, copy constructor, move constructor, and destructor. Since the C++11 standards, the move assignment operator is declared by using “operator=” and it allows you to move one object to another object. In the next post, we explain what a move assignment operator is along with some C++ examples. https://learncplusplus.org/what-is-the-move-assignment-operator-in-modern-c/ When you define your variable you should know well what it is to be used for. Is it a numeric or alphanumeric variable or a binary data that holds all kinds of bytes. If it is a numeric value, what are its limits? If it is between 0 to 255 you don’t need to define with int, an unsigned char (UBYTE) is enough. This may speed up your code 1-4 times faster. If it is a larger number, you can use long, long long, or unsigned long long int for positive numbers. These small rules are […]

How to use a move constructor and copy assignment in modern C++ with C++ Builder CE? In a modern C++, there are a number of features which help you learn, master, and remember the various features and functions of the C++ language. One such feature of modern C++ is the move constructor that allows you to move the resources from one object to another without copying them. In the first post, we explain what the move constructor is in Modern C++. https://learncplusplus.org/what-is-a-move-constructor-in-modern-c/ Using a good quality C++ compiler actively helps you write better code and prompts you with tips on how to use the various capabilities of the C++ standards. In the next post, we explain what a typical declaration of a move constructor is. https://learncplusplus.org/what-is-a-typical-declaration-of-a-move-constructor/ One of the move constructors is forcing a move constructor to be generated by the compiler, and in the next post, we explain the forced (default) move Constructor in Modern C++. https://learncplusplus.org/what-is-a-default-forced-move-constructor-in-modern-c/ Other feature of a C++ are assignment operators such as copy assignment and move assignment operators. In C++, a copy assignment operator is used with “operator=” to create a new object from an existing one. In the next post, we explain […]

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.

Table of Contents What is a copy assignment operator in modern C++? Learn about the copy assignment operator with modern C++ examples Where can I learn modern C++ with free C++ compilers? What is new in C++ Builder CE? 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/ Learn about the copy assignment operator with modern C++ examples LearnCPlusPlus.org has been producing full educational daily articles about C and modern C++ that can be used with C++ Builder, C++ Builder CE, Dev-C++, BCC Compiler and other compilers such as the GCC compiler.

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.
