C++: vectors. Euclidean vectors are sets of values which represent values in a dimensional field. A 2d vector would represent values in x,y space (an ordered pair of coordinates) and a 3d vector would represent values in x,y,z space (an ordered triplet of coordinates). We define the basic definition of the 2d vector as follows: class Vector2D { public: Vector2D (); Vector2D (double ,double ); double dotProduct(Vector2D& ); friend Vector2D& operator +(Vector2D&, Vector2D&); friend std::ostream& operator <<(std::ostream& o, Vector2D& a);...
