WRITE IT IN C$++$ please

Now consider the class Point $2D$ with the function getDistance that returns the distance of a $2D$ point from the origin $(0,0)$ :

Note: Accessors and mutators of the member variables are removed in this exercise.

Re$-$write the definition of the class Point$3$D $($from the previous task$)$ to redefine the function getDistance. The function should return the distance of a $3D$ point from the origin $(0,0,0)$ according to the following formula:

dis $=\sqrt[\phantom{2}]{x^2+y^2+z^2}$

The following program defines a main function that can be used to test the Point$3$D class.

The following is a snapshot of the above program's output.

Using object name, the distance of p$2$ is: $5$

Using object name, the distance of p$3$ is: $3$

Using parent pointer, the distance of p$3$ is: $2\mathrm{.}23607$

Using child pointer, the distance of $p^3$ is: $3$

Note: Even though both pointers are pointing to the same object $($p$3),$ the results of the getDistance calls are different because of the static binding.

In the next task, the classes will be using dynamic binding.
