template <class T1,class T2>
void Copy(T1 s,T1 e, T2 x)
{
	for(; s != e; ++s,++x)
		*x = *s;
}

 
template<class T>
class myostream_iteraotr

// 在此处补充你的代码
};


int main()

	int a[SIZE] = {5,21,14,2,3};
	double b[SIZE] = { 1.4, 5.56,3.2,98.3,3.3};
	list<int> lst(a,a+SIZE);
	myostream_iteraotr<int> output(cout,",");
	Copy( lst.begin(),lst.end(),output); 
	cout << endl;
	myostream_iteraotr<double> output2(cout,"--");
