Template Classes

A template class is a class in which one or more of the data types is left unspecified.
Write template <class T> before the class definition.
The class name Class-name becomes Class-name<T> in all places except:
- The class heading.
- The constructor names.
- The destructor name.
Member functions are instantiated and compiled only as necessary.
Class objects are declared as Class-name<Type> Variable;

Examples: Vector<int> vi(2, 123); Vector<double> vd(3, 4.56); Vector<Rational> vr(5, Rational(2, 3));

Example - The Point template class - point.h (original), point.h(copy) , PointTest.cpp.
