You are designing a class that will be widely used across a large project. The class will often be copied and assigned to other instances. What considerations related to constructors and assignment operators should be taken into account to ensure efficient and correct operation?
- Use of shallow copy.
- Implementing move semantics.
- Avoid using constructors.
- Only use private member variables.
When a class is frequently copied or assigned, it's crucial to consider the efficiency of these operations. Move semantics, introduced in C++11, allow resources to be "moved" from one object to another, without making a copy. This can greatly improve performance. Shallow copy can lead to issues like double deletion, and avoiding constructors or only using private members doesn't address the efficiency of copying or assignment.
