Detailed Description

Example of using the State Pattern in C#.

The State pattern alters the behavior of the class hierarchy based on some state. This is the basis of a Finite State Machine.

In this exercise, the State class is a filter that parses text to remove C++-style line and block comments. It needs to be smart enough to ignore comment characters inside quotes.

The filtering process starts with creating the context that drives the state machine. Internal classes are provided for each state.
