Implement the class Point3D. Put the class definition in the header p1.h and the implementation in the p1.cpp file. You may not have any inline functions defined in the header file. Use the file xercise.cpp to check if your implementation is syntactically correct. • The class has three data members: x, y, and z, which are double. • The default constructor initializes the Point3D to the origin (0, 0, 0), while the working constructor supplies values for x, y, and 2: all doubles in that order. • Create accessors getX(), getY() and getZ(). There are no mutators. (The class is immutable) • Write a member function distance() that returns the distance between the current Point3D (the implicit parameter which will be the left-hand side of an expression) and a second Point3D passed as an explicit parameter (which will be the right-hand-side of the expression). Here is the distance formula for a 3D point: (x₁-x2)² + (y₁ - y₂)² + (Z₁-Z2)² You must both define and implement a feature for the tests to run. For instance, if you define getX() but fail to implement it, then your code will not compile. If your code fails to compile, comment out both the definition and the implementation of the feature that fails.
