(C++) template

Keyword to

* write template functions

* write template classes

* do template metaprogrammming (programs performed at compile time)

Templates make it possible to use one function or class to handle many different data types. Exceptions provide a convenient uniform way to handle errors that occur within classes.

There is no semantic difference between class and typename in a template-parameter [0] .
