C++23 is the informal name for the version of the International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC) 14882 standard for the C++ programming language that follows C++20. The final draft of this version is N4950.
Rule of three. The rule of three (also known as the law of the big three or the big three) is a rule of thumb in C++ (prior to C++11) that claims that if a class defines any of the following then it should probably explicitly define all three: [1] destructor. copy constructor. copy assignment operator. These three functions are special member ...
Object model instruction 0x75 isinst <class> Test if obj is an instance of class, returning null or an instance of that class or interface. Object model instruction 0x27 jmp <method> Exit current method and jump to the specified method. Base instruction 0xFE 0x09 ldarg <uint16 (num)> Load argument numbered num onto the stack. Base instruction 0x02
The Standard Template Library ( STL) is a software library originally designed by Alexander Stepanov for the C++ programming language that influenced many parts of the C++ Standard Library. It provides four components called algorithms, containers, functions, and iterators. [1]
Outline of C++. The following outline is provided as an overview of and topical guide to C++: C++ is a statically typed, free-form, multi-paradigm, compiled, general-purpose programming language. It is regarded as an intermediate-level language, as it comprises a combination of both high-level and low-level language features. [1]
Objects are instances of a class. Object-oriented programming ( OOP) is a programming paradigm based on the concept of objects, [1] which can contain data and code: data in the form of fields (often known as attributes or properties ), and code in the form of procedures (often known as methods ). In OOP, computer programs are designed by making ...
A class defines an implementation of an interface, and instantiating the class results in an object that exposes the implementation via the interface. [3] In the terms of type theory, a class is an implementation—a concrete data structure and collection of subroutines—while a type is an interface. Different (concrete) classes ...
C++ classes. A class in C++ is a user-defined type or data structure declared with any of the keywords class, struct or union (the first two are collectively referred to as non-union classes) that has data and functions (also called member variables and member functions) as its members whose access is governed by the three access specifiers ...
