Question
Which of the following methods is called when the addition operator is used?
__sum__
__add__
__plus__
__addop__
Solution
The method that is typically called when the addition operator is used in programming, specifically in object-oriented programming languages like Python, is __add__
. This is known as a special method (or dunder method) that allows for operator overloading, enabling the use of the +
operator to combine objects in a defined way.
Explanation
- Operator Overloading: In programming, you can define how operators behave with custom objects. The
__add__
method is crucial for defining how two instances of a class should be added together using the+
operator. - Syntax: To use the
+
operator for object instances, the__add__
method of the respective class needs to be implemented. - Example: For example, in Python, if you have a class
Vector
, you can implement the__add__
method to allow vector addition when two vector instances are added.
Overall, __add__
serves as the designated method for handling addition operations in the context of operator overloading in various programming languages.
