I am writting a c++ progarm and I got a most, but when i debug this program it giving me negative orginal points. Can you please take a look.

Specify, design and implement a class that can be used to keep track of the position of a point in three-dimensional space. For example, consider the point drawn here: y-axis | | | | | x-axis .-----------------------------> / / / . ( 2.5, 0 ,2.0) / / / z-axis The point shown above has three coordinates: x = 2.5, y = 0, and z = 2.0. Include member functions to set a point to a specific location, to shift a point a given amount along one of the axes, and to retrieve the coordinates of a point. Also provide member functions that will rotate the point by a specified angle around a specied axis. To compute these rotations, you will need a bit of trigonometry. Suppose you have a point with coordinates x,y,and z. After rotating this point by an angle alpha,the point will have new coordinates,which we'll call x',y', and z'. The equation for the new coordinates use the math.h library functions sin and cos, as shown here: After an alpha rotation around the x-axis: x' = x y' = y cos(alpha) - z sin(alpha) z' = y sin(alpha) + z cos(alpha) After an alpha rotation around the y-axis : x' = x cos(alpha) + z sin(alpha) y' = y z' = -x sin(alpha) + z cos(alpha) After an alpha rotation around the z-axis: x' = x cos(alpha) - y sin(alpha) y' = x sin(alpha) + y cos(alpha) z' = z Note: alpha is in radians use this formula to convert degrees to radians R = ( C * PI) / 180 where R : radians C : degrees PI : constant pi = 3.1415926.
