It also includes member functions to manipulate CPoint and POINT structures.
A CPoint object can be used wherever a POINT structure is used. The operators of this class that interact with a "size" accept either CSize objects or SIZE structures, since the two are interchangeable.
Note
This class is derived from the tagPOINT structure. (The name tagPOINT is a less commonly used name for the POINT structure.) This means that the data members of the POINT structure, x and y, are accessible data members of CPoint.
