template specialization compile error

[Naveen]

Hello All.
I am trying to compile this code on Borland 5.6.4. The compiler is
throwing up this error message:

"main.cpp": E2299 Cannot generate template specialization from 'B<T>'
at line 12

Any help to fix this would be appreciated.

Two errors are apparent to me.

// -------------------- Code Starts here ----------------------------
//
#include <iostream>

class A { };

template <typename T>
class B : public A
{
public: B() { }
};

class Testing
{
public:
template <typename T>

void load( int key, B<T>& sort = B<T>())

ISO C++ forbids binding rvalues to non-const references. So the reference
should be to a const object.

{

}
};

void main()

main has never ever in the history of C++ returned void. The return type is
int.

{
Testing ab;
ab.load<int>(10);
}
