Write the definition for a class named Vector2D that stores information about a two-dimensional vector. The class should have functions to get and set the x and y components, where x and y are integers.Next, overload the * operator so that it returns the dot product of two vectors. The dot product of two-dimensional vectors A and B is equal to(Ax * Bx) + (Ay * By).Finally, write a main subroutine that tests the * operation.
