Template Functions

A template function contains the code necessary for an algorithm, but does not specify the data types involved.
typedef Templates
- Write typedef type T;
- Use T in place of the type in the function.
- T may represent only one type.
C++ Template Functions
- Write template <class T> before the function definition.
- Use T in place of the type in the function.
- The function is separately instantiated for as many types as necessary.
- More than one template type is possible in a single function, e.g., template <class T1, class T2>
Example - TypedefSort.cpp, rational.h (original), rational.h (copy), rational.cpp.
Example - TemplateSort.cpp.
