Working with Class Templates

|  Overview |  How Do I

You can use class templates to create a family of classes that operate on a type.

template <class T, int i> class TempClass
{
public:
    TempClass( void );
    ~TempClass( void );
    int MemberSet( T a, int b );
private:
    T Tarray[i];
    int arraysize;
};

In this example, the templated class uses two parameters, a type T and an int i. The T parameter can be passed any type, including structures and classes. The i parameter has to be passed an integer constant. Because i is a constant defined at compile time, you can define a member array of size i using a standard array declaration.
