7.4 Templates

Templates provide the ability to define C++ classes which support generic programming techniques. Templates can be considered as a powerful kind of macro facility. When a templated class or function is used with a specific class or type, such as float or int, the corresponding template code is compiled with that type substituted in the appropriate places.
