Move Assignment Operator

Seen in CS247 - Software Engineering Principles, here’s an example:

Node& Node::operator=(Node&& other) {
	std::swap(data, other.data);
	std::swap(next, other.next);
	return *this;
}

Move Constructor vs. Move Assignment Operator

A a("Hello");
A c("World");
 
A b = std::move(a);  // Move constructor is called to transfer resources from 'a' to 'b'
a = std::move(c);  // Move assignment operator is called to transfer resources from 'c' to 'a'

Move Constructor is invoked when a new object is being initialized with an rvalue. Move Assignment Operator is called when an already initialized object a is being assigned an rvalue.

In both cases, the move operations are used to take advantage of movable resources, such as dynamically allocated memory or expensive-to-copy objects. By moving resources instead of making copies, it can result in improved performance and reduced overhead.
