Write a complete C++ class to represent a sphere in three-dimensional space. Your class should consist of a header (sphere. h) and an implementation (sphere. cpp) file as described below. The sphere class should have the following (private) attributes and (public) methods: Attributes:

x coordinate (an int), can be negative
y coordinate (an int), can be negative
z coordinate (an int), can be negative
radius (a double), must be greater than 0.0
Methods

A default constructor that creates a sphere of radius 10 at position 0,0,0
A constructor with parameters for x, y, z, and radius
void move - moves the sphere the given distances (therefore changing its x , y, and z attributes)
void setRadius(double r) - changes the sphere's radius to r, or to 10.0 if r is invalid
int getX() - returns the sphere 's x coordinate
int getY() - returns the sphere 's y coordinate
int getZ() - returns the sphere 's y coordinate
double getRadius() - returns the sphere's radius
double getVolume() - returns the sphere's area
void displaySphere() - displays the sphere's attributes like this: "radius 10.0 at point x = 12, y = 17, z=11"

Formatting rows and columns is similar to cell formatting. in an openoffice calc spreadsheet, you can format data entered into rows and columns with the of the rows and columns options. you can insert rows and columns into, or delete rows and columns from, a spreadsheet. use the insert or delete rows and columns option on the insert tab. alternatively, select the row or column where you want new rows or columns to appear, right-click, and select insert only row or only column options. you can hide or show rows and columns in a spreadsheet. use the hide or show option on the format tab. for example, to hide a row, first select the row, then choose the insert tab, then select the row option, and then select hide. alternatively, you can select the row or columns, right-click, and select the hide or show option. you can adjust the height of rows and width of columns. select row and then select the height option on the format tab. similarly, select column, then select the width option on the format tab. alternatively, you can hold the mouse on the row and column divider, and drag the double arrow to the position. you can also use the autofit option on the table tab to resize rows and columns.
