* # design collections of model objects using sequential containers and multi-dimensional arrays to solve a systems or business problem* # create function objects and closures to customize a programming solution for a particular application * # model generalization and specialization using inheritance hierarchies to minimize the duplication of code* # model polymorphic behavior using interfaces, virtual functions and templates (generics) to amplify the reusability of code* # implement solution components using algorithms and iterators of the standard template library to utilize existing technologies* # design multi-task solutions using threading libraries to improve the performance of a program
