career in video games and embedded software • Started using C++ in 1995 • First cross-platform project in 1994Cross-Platform Architecture Goals • Take advantage of all platforms • Focus on the compiler • Minimize classes, an illustrative example from a larger project • Project build issues • Inclusion of platform-specific header files • Concept hierarchies • Class and Function DesignOCP: The Open–Closed Principle Adding new revisions to a feature has no effect on previously-implemented revisions.What is a Platform? • A specific set of features • A feature is an abstract unit of functionality requiring implementations
