State Design Pattern
Intent 01 Allow an object to alter its behavior when its internal state changes. The object will appear to change its class. An object-oriented state machine wrapper + polymorphic wrappee + collaboration Problem A monolithic object’s behavior is a function of its state, and it must change its behavior at run-time depending on that state.C++ FAQ

If I had any pretensions to knowing it all when I wrote my assignment-operator article (" The Anatomy of the Assignment Operator ," C++ Report, Nov/Dec 1997), they didn’t last long afterwards. The assignment-operator article drew a huge response, with a lot of people sending me corrections and disagreements of various kinds.

qctemplate - An easy to use template engine for C++/Qt
If you are familiar with string template engines like Smarty (PHP) or Django (Python), then you know what template engines are about: to facilitate the separation of application code from presentation. Template engines are much less common in C++ than in web development, but things are slowly changing. Today, C++ application need to generate more and more web pages.One of the most commonly used types is string , and string is an immutable class, meaning that once it’s assigned the type cannot change. To change the state of an immutable class, a new class needs to be instantiated. Developers rarely consider using immutable classes because our logic says immutable classes are inefficient. Yet one of the most used types, string , is immutable. Efficiency can be measured multiple ways, but for today’s hardware efficiency is best measured as code that gets in the way of the processor very little.
