class template Prototype?

Hi,

I am having a problem declaring a class template prototype, i.e:

template <class type>
class foobar<type>; // the prototype

// some code...

template <class type>
class foobar { // the definition
// some other code...
};

My VC++ compiler returns (at the “class foobar<type>;” line):
error C2143: syntax error : missing ';' before '<'

And when I just set the prototype to “class foobar;” it returns:
error C2989: foobar: template class has already been defined as a non-template class

For clarity I should point out that the class prototype, definition and functions are all in
the same file and compile fine if I don’t add the prototype and the code that requires it.
So the question is how does one declare a class template prototype?

Any help is greatly appreciated.

You were close...

Code:

---

template<class type> class foobar;
template<class type> class foobar { };

int main()
{
    foobar<int> fb;

    return 0;
}//main

thanks alot mate!!

here's a templated class implementing a crude templated array. The class needs to be flushed out to make it useful for anything other than demonstrating the syntax of templated class method definitions, so use it as you may:

Code:

---

template<class T>
class Array
{
  public:
        T * pT;
        int size;
        Array();
        Array(const Array & rhs);
        ~Arrray () {delete [] pT;}
        //etc.
};
 
template<class T> Array<T>::Array : size(10)
{
  pT = new T[size];
}
 
template<class T> Array<T>::Array(const Array & rhs)
{
  for(int i = 0; i < size; ++i)
        pT[i] = rhs.pT[i];
}
 
int main()
{
  Array<int> fb;
}
