  2. Operator overloading - Wikipedia

    en.wikipedia.org/wiki/Operator_overloading

    Operator overloading has often been criticized [2] because it allows programmers to reassign the semantics of operators depending on the types of their operands. For example, the use of the << operator in C++ a << b shifts the bits in the variable a left by b bits if a and b are of an integer type, but if a is an output stream then the above ...

  3. 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 ...

  4. Function overloading - Wikipedia

    en.wikipedia.org/wiki/Function_overloading

    In some programming languages, function overloading or method overloading is the ability to create multiple functions of the same name with different implementations. Calls to an overloaded function will run a specific implementation of that function appropriate to the context of the call, allowing one function call to perform different tasks ...

  5. Polymorphism (computer science) - Wikipedia

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

    Christopher Strachey chose the term ad hoc polymorphism to refer to polymorphic functions that can be applied to arguments of different types, but that behave differently depending on the type of the argument to which they are applied (also known as function overloading or operator overloading). [5]

  6. 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 than).

  7. Virtual function - Wikipedia

    en.wikipedia.org/wiki/Virtual_function

    Overloading occurs when two or more methods in one class have the same method name but different parameters. Overriding means having two methods with the same method name and parameters. Overloading is also referred to as function matching, and overriding as dynamic function mapping.

  8. Overloading - Wikipedia

    en.wikipedia.org/wiki/Overloading

    The term overloading may refer to: Function overloading , a software engineering process whereby multiple functions of different types are defined with the same name Operator overloading , a software engineering process whereby operators (e.g. + or - ) are treated as polymorphic functions having different behaviors depending on the types of ...

  9. Operators in C and C++ - Wikipedia

    en.wikipedia.org/wiki/Operators_in_C_and_C++

    Operators that are in the same cell (there may be several rows of operators listed in a cell) are grouped with the same precedence, in the given direction. An operator's precedence is unaffected by overloading. The syntax of expressions in C and C++ is specified by a phrase structure grammar. [7] The table given here has been inferred from the ...
