In the [[C++|C++ programming language]], the move assignment operator (<code>=)</code>, is used for transferring ownership (moving) of ana an already instantiatedtemporary object or resource to another existing object. The move assignment operator, like most of the other C++ operators, can be [[Operator overloading|overloaded]]. It is one the of the [[special member functions]].<ref>{{Cite journal|title = Special member functions|url = https://en.wikipedia.org/w/index.php?title=Special_member_functions&oldid=662581955|journal = Wikipedia, the free encyclopedia|language = en}}</ref>
If the move assignment operator is not explicitly defined, then the compiler will generate an implicit move assignment operator ([[C++11]] and newer). The parametersparameter of a move assignment operator areis an [[rvalue reference]] (T&&) to type ''T''; ''T'' being the object that defines the move assignment operator. The move assignment operator is different than a [[move constructor]] because a move assignment operator is called on an existing object, as a move constructor would be called on an object being created. One must somehow also signify the other object's data is not valid anymore, and has been moved.
