question 1:
template
class Foo
{
T tVar;
public:
Foo(T t) : tVar(t) { }
};
class FooDerived : public Foo { };
FooDerived fd;
What is preventing the above code from being legal C++?
A. FooDerived is a non-template class that derives from a template class.
B. tVar is a variable of an unknown type.
C. A constructor must be provided in FooDerived.
D. FooDerived uses the non-C++ type std::string.
E. The initialization of tVar occurs outside the body of Foo's const

template
class Foo
{
T tVar;
public:
Foo(T t) : tVar(t) { }
};
class FooDerived : public Foo { };
FooDerived fd;
Why the code above NOT syntactically correct C++?
1) FooDerived uses the non-C++ type std::string.
2) FooDerived is a non-template class that derives from a template class.
3) The initialization of tVar occurs outside the body of Foo's constructor.
4)tVar is a variable of an unknown type.
5) A constructor must be provided in FooDerived.
从bb上看到的,谢谢!

这两天因缘际会认识了很多90后的孩子,颇受冲击,慢慢的认识到自己开始老了。首先
很惊讶于他们的娱乐方式,打三国杀,k歌,心说这都我们当年无聊时干的事啊,而且k
的歌跟我们上大学时k的一模一样,周杰伦,s.h.e,光良...居然还有人听王菲的…我一
直以为他们应该听快男,超女那帮人的呢,可见华语乐坛已然快出现断层了。而且这帮
孩子还看过还珠格格,看过郑渊洁,我都觉得不可思议,还珠格格是我刚上初中时看的
,这帮孩子应该刚上小学啊,怎么能看得懂呢?郑渊洁是我上小学时为了多认字时买着
看的,90后的孩子应该还在牙牙学语或哺乳状态啊,而且他后来写的东西,就是我高中
时期,都太成人化了并且质量也下降了,不理解90后怎么会喜欢他的。总之从娱乐审美
来讲,好像80后90后喜欢的是一样的东西。这个其实应该归咎于80后,我的同仁们,就
没创造出太有意思的文化供下一代消费。不知道这帮娃儿们是不是也是打着轩辕剑,仙
剑,红警,星际,CS,魔兽,大菠萝长大的?
再有就是钦佩于80后的素质们,他们的激情远胜于当初的我们,至少比我强多了。他们
的思想比我们当年的自由,估计这要归功于他们60后的家长们... 阅读全帖

想想上一代的识字率,大学普及率,再看看现在的。这就是看你要比较top1%的还是大
众的了,TVaR和mean的区别而已。金正日家族比很多中国人都有钱,朝鲜可没中国富裕

来自主题: Actuary版 - 征C/4的考友。。。
你说得对!289是2007以前的真题,由于考试范围改变,是有很多新的东西没有覆盖,
比如TVaR之类。但一般manual里面都会指出哪些是新东西,outpost上面也有一个帖子
总结了289没有覆盖的内容。这些内容只能找ASM题目练习了。
我强调289的原因是,289加 May 2007是最接近真题的。Abe自己出的题目跟真题差别还
是很大的,Abe的题目过于复杂,计算难度大,但叙述方式又直截了当。做Abe题目多了
,会不适应真题。就像有人在outpost上说的,SOA总是能够出一些叙述奇怪的题目,让
写manual的人很难模仿,但其实真正需要算的步骤不多。
所以说,考前还是应该多看SOA自己的题目,适应其独特的叙述方式。

啊。
