构造函数的try怎么用不了啊
class Base
{
int i;
public:
class BaseException {};
Base(int I):i(I){throw BaseException();}
};
class Derived:public Base
{
public:
class DeriveException
{
const char* msg;
public:
DeriveException(const char* pmsg):msg(pmsg){}
const char* what(){return msg;}
};
Derived(int I) try :Base(I)
{
cout < < "This won 't print " < <endl;
}
catch (BaseException& t)
{
throw DeriveException( "Base subject throw ");;
};
};
编译不过，提示好多错误，书上都是这么写的啊!

VC6吧？扔了，换devcpp、VC2005

[解决办法]
Derived(int I):Base(I)
{
try
{
cout < < "This won 't print " < <endl;
}
catch (BaseException& t)
{
throw DeriveException( "Base subject throw ");
}
}
=======================================================================
Derived(int I) try :Base(I)
{
cout < < "This won 't print " < <endl;
}
catch (BaseException& t)
{
throw DeriveException( "Base subject throw ");;
};
