Need help with my code

student1 (8)
I have 3 classes which are point 1DClass, Point 2DClass and Point 3DClass.
Point 1DClass contains data member x
Point 2DClass contains data member y and inherits data member x from point 1DCLass
Point 1DClass contains data member z and inherits the other two data members.

these co-ordinates are to offer methods for accessing, mutating and displaying the values of co-ordinates. then multiple constructors will be provided by function overloading. this is the function overloading i needed to do.

A- Accepting no parameters and setting all co-ordinates to 0.

B- Accepting all co ordinates as arguments and setting data members to arguments.

I was wondering if anyone would be able to tell me if i have done this correctly within my code. If not how can i do it?
Thanks :)
