C++自定義異常處理

自定義異常類

class MyException
{
public:
    MyException()
    {
    }

    MyException(char* str)
    {
        msg = str;
    }

    MyException(MyException& rhs)
    {
        this->msg = rhs.msg;
    }

    std::string msg;
};

 

拋出異常

void CallWithException()
{
    char msg[1024] = { 0 };
    sprintf(msg, "Exception: %s", "shit");
    throw MyException(msg);
}

 

捕捉異常

try
{
    CallWithException();
}
catch (MyException& e)
{
    cout << e.msg;
}
