You are designing a Vector class to represent 2D vectors, and you want to add two vectors using the + operator. How would you implement this?

Create a new class, VectorAdder, to handle vector addition.
Implement a separate function, add_vectors(), for adding vectors.
Overload the + operator in the Vector class, so it combines the x and y components of the vectors.
Overload the += operator for the Vector class to support in-place addition of vectors.

The correct approach is to overload the + operator in the Vector class, allowing for a natural syntax for vector addition. This is a common operator overloading scenario.
