A.3. IOStream Examples

This section presents several longer examples of the IOStream library. In “Overloading Streams” on page 324, we demonstrate overloading operator<<() and operator>>() for String objects. Let's do this for class Hue, a structure that stores and manipulates composite objects.

Hue

For simplicity, we've made Hue a structure with no constructor and all public data members. Hue objects consists of a character array, an integer, and a float. The main behavior we've given Hue objects is stream input and output by overloading operator<<() and operator>>(). Here is header file Hue.h.
