帮忙看看错在哪

[APIandMFC]

#include<iostream>
using namespace std;
class Base
{
	int i;
public:
	class BaseExcept{};
	Base(int ii):i(ii){throw BaseExcept();}//成员对象初始化时抛出了异常。
};
class Derived:public Base
{
public:
	class DerivedExcept
	{
		const char* msg;
	public:
		DerivedExcept(const char* message):msg(message){}
		const char* what()const{return msg;}
	};
	Derived(int j)try:Base(j)
	{
		cout<<"This won't print"<<endl;
	}
	catch(BaseExcept&)
	{
		throw DerivedExcept("Base subobject threw");;
	}
};
int main()
{
	try
	{
		Derived d(3);
	}
	catch(Derived::DerivedExcept& d)
	{
		cout<<d.what()<<endl;
	}
	return 0;
}

请告诉我你用的是什么编译器 谢谢.

lz应该多准备几个编译器！

vc6.0对函数级try catch不支持！

程序没有错误啊，输出：

Base subobject threw

vc++ 2008 express，补上
