/* create a class point that represents a three dimensional co-ordinates system. Each object of Point have coordinates, (x,y,z) and methods to assign coordinates to the point objects. Add a method to calculate the distance from origin and to print the point in the form of (x,y,z)

Output Sample:
Enter the coordinates of x, y and z
8
9
10
The distance from the origin is: 15.6525
