示例1: main

int main(){

	SmartPtr<int> sPtr;
	sPtr.Reset(new int(999));

	cout << "Dislaying content of Smart Ptr:[" << *sPtr << "]" << endl;

	SmartPtr<char> charPtr(new char('R'));
	cout << "Char Smart Pointer:[" << *charPtr << "]" << endl;

	SmartPtr<int> iSPtr = sPtr;
	cout << "Copy Contructor of int Smart Ptr:[" << *iSPtr << "]" << endl;

	SmartPtr<int> isPtr2(sPtr);
	cout << "Copy Assignment of int Smart Ptr:[" << *isPtr2 << "]" << endl;

#if 0
	std::shared_ptr<int> foo;
	cout << "empty shared ptr:[" << *foo << endl;
#endif // 0

	//Followign code will fail as the smart pointer is empty, whic is the case for shared ptr as well
	SmartPtr<int> isPtr3;
	isPtr3 = isPtr2;
	cout << "Copy Assignment of int Smart Ptr:[" << *isPtr3 << "]" << endl;
	//_getche();
	return 0;
