2. Rule of three (C++ programming) - Wikipedia

   en.wikipedia.org/wiki/Rule_of_three_(C++...

   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 ...

3. Defensive programming - Wikipedia

   en.wikipedia.org/wiki/Defensive_programming

   Defensive programming is an approach to improve software and source code, in terms of: General quality – reducing the number of software bugs and problems. Making the source code comprehensible – the source code should be readable and understandable so it is approved in a code audit. Making the software behave in a predictable manner ...

4. "Hello, World!" program - Wikipedia

   en.wikipedia.org/wiki/"Hello,_World!"_program

   A "Hello, World!" program is generally a simple computer program which emits (or displays) to the screen (often the console) a message similar to "Hello, World!" while ignoring any user input. A small piece of code in most general-purpose programming languages, this program is used to illustrate a language's basic syntax.

5. C++ classes - Wikipedia

   en.wikipedia.org/wiki/C++_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 ...

   The C++ Core Guidelines [83] are an initiative led by Bjarne Stroustrup, the inventor of C++, and Herb Sutter, the convener and chair of the C++ ISO Working Group, to help programmers write 'Modern C++' by using best practices for the language standards C++11 and newer, and to help developers of compilers and static checking tools to create ...

7. Initialization (programming) - Wikipedia

   en.wikipedia.org/wiki/Initialization_(programming)

   In computer programming, initialization or initialisation is the assignment of an initial value for a data object or variable. The manner in which initialization is performed depends on the programming language, as well as the type, storage class, etc., of an object to be initialized. Programming constructs which perform initialization are ...

8. Method (computer programming) - Wikipedia

   en.wikipedia.org/wiki/Method_(computer_programming)

   A method in object-oriented programming (OOP) is a procedure associated with an object, and generally also a message. An object consists of state data and behavior; these compose an interface, which specifies how the object may be used. A method is a behavior of an object parametrized by a user. Data is represented as properties of the object ...

9. Virtual method table - Wikipedia

   en.wikipedia.org/wiki/Virtual_method_table

   In computer programming, a virtual method table ( VMT ), virtual function table, virtual call table, dispatch table, vtable, or vftable is a mechanism used in a programming language to support dynamic dispatch (or run-time method binding ). Whenever a class defines a virtual function (or method ), most compilers add a hidden member variable to ...
