  2. Operator overloading - Wikipedia

    en.wikipedia.org/wiki/Operator_overloading

    Because operator overloading allows the original programmer to change the usual semantics of an operator and to catch any subsequent programmers by surprise, it is considered good practice to use operator overloading with care (the creators of Java decided not to use this feature, [3] although not necessarily for this reason).

  3. 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.

  4. 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.

  5. Ad hoc polymorphism - Wikipedia

    en.wikipedia.org/wiki/Ad_hoc_polymorphism

    The previous section notwithstanding, there are other ways in which ad hoc polymorphism can work out. Consider for example the Smalltalk language. In Smalltalk, the overloading is done at run time, as the methods ("function implementation") for each overloaded message ("overloaded function") are resolved when they are about to be executed.

  6. Loop fission and fusion - Wikipedia

    en.wikipedia.org/wiki/Loop_fission_and_fusion

    This issue can be avoided in C++ by using a different syntax that does not rely on the compiler to remove unnecessary temporary allocations (e.g., using functions and overloads for in-place operations, such as operator+= or std::transform).

  7. Operator (computer programming) - Wikipedia

    en.wikipedia.org/wiki/Operator_(computer...

    In languages that support operator overloading by the programmer (such as C++) but have a limited set of operators, operator overloading is often used to define customized uses for operators. In the example IF ORDER_DATE > "12/31/2011" AND ORDER_DATE < "01/01/2013" THEN CONTINUE ELSE STOP , the operators are: > (greater than), AND and < (less ...

  8. Move assignment operator - Wikipedia

    en.wikipedia.org/wiki/Move_assignment_operator

    The move assignment operator, like most C++ operators, can be overloaded. Like the copy assignment operator it is a special member function . If the move assignment operator is not explicitly defined, the compiler generates an implicit move assignment operator ( C++11 and newer) provided that copy / move constructors , copy assignment operator ...

  9. Function overloading - Wikipedia

    en.wikipedia.org/wiki/Function_overloading

    The first is taken in C++: "in C++, there is no overloading across scopes." [ 12 ] As a result, to obtain an overload set with functions declared in different scopes, one needs to explicitly import the functions from the outer scope into the inner scope, with the using keyword.
