Definition: A template is a C++ feature that allows functions and classes to be defined with any type.
With a non-templated function, the parameters to that function are declared to be of a particular type. By defining a template function, that function can be called with a compatible type and the compiler will use the type derived from the parameter.
With template classes such as the Vector class in the STL, it is possible to create a vector class (an array that can change size at runtime) of say payroll objects. Because of the strict typing, only payroll obejcts can be stored in the list.
