  2. Operator overloading - Wikipedia

    en.wikipedia.org/wiki/Operator_overloading

    Microsoft added operator overloading to C# in 2001 and to Visual Basic .NET in 2003. Scala treats all operators as methods and thus allows operator overloading by proxy. In Raku, the definition of all operators is delegated to lexical functions, and so, using function definitions, operators can be overloaded or new operators added.

  3. Input/output (C++) - Wikipedia

    en.wikipedia.org/wiki/Input/output_(C++)

    The cerr and clog objects are also of type ostream, so they overload that operator as well. The cin object is of type istream, which overloads the right bit-shift operator. The directions of the bit-shift operators make it seem as though data is flowing towards the output stream or flowing away from the input stream.

  4. Ad hoc polymorphism - Wikipedia

    en.wikipedia.org/wiki/Ad_hoc_polymorphism

    This is an example of overloading or more specifically, operator overloading. Note the ambiguity in the string types used in the last case. Consider "123" + "456" in which the programmer might naturally assume addition rather than concatenation. They may expect "579" instead of "123456". Overloading can therefore provide different meaning, or ...

  5. Operators in C and C++ - Wikipedia

    en.wikipedia.org/wiki/Operators_in_C_and_C++

    All the operators (except typeof) listed exist in C++; the column "Included in C", states whether an operator is also present in C. Note that C does not support operator overloading. When not overloaded, for the operators && , || , and , (the comma operator ), there is a sequence point after the evaluation of the first operand.

  6. Curiously recurring template pattern - Wikipedia

    en.wikipedia.org/wiki/Curiously_recurring...

    The curiously recurring template pattern (CRTP) is an idiom, originally in C++, in which a class X derives from a class template instantiation using X itself as a template argument. [1] More generally it is known as F-bound polymorphism , and it is a form of F -bounded quantification .

  7. Move assignment operator - Wikipedia

    en.wikipedia.org/wiki/Move_assignment_operator

    Check if the object calling the operator is not calling the operator on itself. The current object's data is de-allocated. The object that is being moved from must have its data marked as nullptr (or something to signify the move) The operator must return a reference to "*this". Consider the following move assignment operator for a simple ...

  8. C++/CLI - Wikipedia

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

    (In reverse, this also means that for .NET framework ref classes, reference operator overloading often is implicitly implemented in C++/CLI.) For example, comparing two distinct String references (String^) via the operator == will give true whenever the two strings are equal. The operator overloading is static, however. Thus, casting to Object ...

  9. Assignment operator (C++) - Wikipedia

    en.wikipedia.org/wiki/Assignment_operator_(C++)

    In the C++ programming language, the assignment operator, =, is the operator used for assignment.Like most other operators in C++, it can be overloaded.. The copy assignment operator, often just called the "assignment operator", is a special case of assignment operator where the source (right-hand side) and destination (left-hand side) are of the same class type.
