   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.

3. Augmented assignment - Wikipedia

   en.wikipedia.org/wiki/Augmented_assignment

   Augmented assignment (or compound assignment) is the name given to certain assignment operators in certain programming languages (especially those derived from C ). An augmented assignment is generally used to replace a statement where an operator takes a variable as one of its arguments and then assigns the result back to the same variable.

4. Composition over inheritance - Wikipedia

   en.wikipedia.org/wiki/Composition_over_inheritance

   Composition over inheritance (or composite reuse principle) in object-oriented programming (OOP) is the principle that classes should favor polymorphic behavior and code reuse by their composition (by containing instances of other classes that implement the desired functionality) over inheritance from a base or parent class.

   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 ...

6. Pointer (computer programming) - Wikipedia

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

   In computer science, a pointer is an object in many programming languages that stores a memory address. This can be that of another value located in computer memory, or in some cases, that of memory-mapped computer hardware. A pointer references a location in memory, and obtaining the value stored at that location is known as dereferencing the ...

7. Outline of C++ - Wikipedia

   en.wikipedia.org/wiki/Outline_of_C++

   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]

8. Assignment (computer science) - Wikipedia

   en.wikipedia.org/wiki/Assignment_(computer_science)

   Assignment (computer science) In computer programming, an assignment statement sets and/or re-sets the value stored in the storage location (s) denoted by a variable name; in other words, it copies a value into the variable. In most imperative programming languages, the assignment statement (or expression) is a fundamental construct.

9. Assertion (software development) - Wikipedia

   en.wikipedia.org/wiki/Assertion_(software...

   In computer programming, specifically when using the imperative programming paradigm, an assertion is a predicate (a Boolean-valued function over the state space, usually expressed as a logical proposition using the variables of a program) connected to a point in the program, that always should evaluate to true at that point in code execution ...
