Answer to Question #247539 in C++ for junaid

Question

A housing society is represented by a 3D plane. We have a class house which

stores the location of a house of three persons using x, y and z coordinates of

plane. Another class market which stores the location of a main market. Each class

should initialize the data members using parameterized constructor. Keep the data

members of all the classes private. Also display the location of houses and market.

Calculate the distance of houses of all the persons from the market and display

which person’s house is far away from the market. Also display which person has

nearest distance from the market.

The class manager has the access to both class house and market so it swaps the

location of the market with the house of a person that has the largest distance

with the market. in C++
