POINT+Class

Implement a POINT Class for 3-dimensional points (x,y,z). Your implementation should include 1) A default constructor 2) A destructor 3) NEGATE function to transform the point into its negative 4) NORM function to return the point's distance from the orgin (0,0,0) 5) PRINT function Hint: Data members are int x, int y and int z.

Write a simple program to test your POINT Class.

Implement a TIME Class. Each object of this class will represent a specific time of the day, storing the hours, minutes and seconds as integers. Include 1) Constructor 2) Destructor 3) Display function to show the current timing  4) Reset( int h, int m, int s) function to reset the current time of an existing object 5) Advance(int h, int m, int s) function to advance the current time of an existing object  Write a simple program to test your TIME Class.
