C++ designHomeworkC++ style• efficient with inline functions• don’t need knowledge of data structure• modular• re-usableHep3VectorF hits[100];// do some workfloat r = hits[i].mag();• later, we’ll get rid of the fixed or dynamic arraysSupposeclass Hep3VectorF {public:Hep3VectorF();Hep3VectorF(float x, float y, float z)Hep3VectorF(const Hep3VectorF &v);inline float x();inline float y();inline float z();inline float phi();inline float cosTheta();inline float mag();private:float r, cos_theta, phi;};• write the implementation for this class• constructors take x, y, and z as arguments, but mustintialize r, cos(theta), and phi data members• try clhep/threeVector0.C; it should still workwith this small change// #include #include “ThreeVector.h”• write a program to exercise x(), y(), and z()member functionsBABAR C++ Course 80 Paul F.
