周芷若,这种女人,好不好?好。
但是这种好看上去更像是取悦他人的好,是那种希望大家都夸她好,都喜欢她的那种好
。这种优秀的里面有着许多的自卑,依赖的情绪在里面,是那种,你要她做什么她就做
什么,只要你喜欢就好的好。这种女人不好吗?好,但是,我真的挺难喜欢的。
我喜欢的是那种喜欢表达,喜欢袒露,跟我一样有喜怒哀乐的,活生生的真实的人。
在小说里那种女人讲究三从四德的社会背景下,赵敏这种敢爱敢恨的性格,多性感啊。
试想下,你要是张无忌,是愿意娶一个每天晚上你说要就要,你说不要就不要的女人好
,还是你说要的时候不一样给的,她说要的时候,你不给都不行的女人好呢?
小屁孩肯定选第一种。为什么性和谐这么重要?不就是因为,性,这东西,把两人都脱
光光了,你越和谐,接纳度就越高,坦诚相待,把身体那么丑的地方都暴露给对方看了
,她如果依然喜欢,可不就是真爱嘛。
对于一个把我变成绅士的女人,我敬她;对于一个把我变成淫棍的女人,我畏她;对于
一个让我时常想当绅士,时常想做淫棍的女人,我爱她。
用现在话说, 周芷若把自己最坏最冷最算计的一面, 都用在了对付最亲密的人 。
而赵敏是对天下人都不好 ,唯独对张好, 选谁还用问?
周芷若黑化前 是传说中别人家的孩子, 啥都好。 善良上进又温柔 ,唯一伤害过的人
, 就是光明顶上的张无忌 。
你们体会一下 而且周芷若格局真是堪忧 ,师傅让发誓就发誓 ,天大地大家长最大 。
有人说她没有独立人格 ,我同意, 但不论因仅论果 ,这是周芷若自己权衡后的选择
, 无论是赵敏恃宠叛家成功 。
还是纪晓芙宁死不屈 都干不出这样的事儿来, 听说修改版还想当皇后了?
发誓了你就守誓呗 ,她不 ,还要撩还要争还要结婚,所以到底是怎么回事 。
你是突然觉得师傅是个屁了 ,还是你命由你不由天发的誓不怕了不算了, 还是故意布
局联姻发展峨眉呢?
行 女神那是想要谈恋爱又要活命 ,好汉不吃眼前亏所以骗师傅玩呢 ,很好啊, 被逼
的誓言可以不算。
当然是宽容你啊 ,相信你是真爱。 那你盗倚天屠龙又是什么操作?
其实个人认为周芷若和朱九真性质是一样的 ,你们体会一下 ,只不过朱九真多了一个

从国务院得到消息,第一季度EB3C获批770+,已经超过了季度限额,本财政年度EB3C排期推进缓慢的原因就是广州领事馆的CP来势汹汹,从国务院公布的demand数据来看,CY2004以前美国本土已批和待批的EB3C占小头。
去年第一季度EB3C也只有800+获批,结果全年以3500个实批名额做收。。

I think what he means is in Java, multidimensional array is not true
multidimensional array, say for example:
int[][] matrix = new int[][] {{1,2},{3,4,5}};
So in each row, you can end up with different columns. This is because Java'
s multidimensional array doesn't store rows in contiguous memory location,
therefore allowing different lengths in columns.
However, in C/C++, multidimensional arrays are true multidimensional arrays
like the definition in mathematics:
int matrix[][2] = {{1,2},{3,4}};
And you can use matrix[i][j] to access (i,j)-th element. And you can also
use pointer to access multidimensional arrays since they are stored in
contiguous memory location like
int *p = &matrix[0];
int elem = *(*(p+i)+j);

: I think what he means is in Java, multidimensional array is not true
: multidimensional array, say for example:
: int[][] matrix = new int[][] {{1,2},{3,4,5}};
: So in each row, you can end up with different columns. This is because Java'
: s multidimensional array doesn't store rows in contiguous memory location,
: therefore allowing different lengths in columns.
: However, in C/C++, multidimensional arrays are true multidimensional arrays
: like the definition in mathematics:
: int matrix[][2] = {{1,2},{3,4}};
: And you can use matrix[i][j] to access (i,j)-th element. And you can also

java is created for business, true business.
business 唯一关心就是money.
如果连这最基本的前提都搞不懂,就不要聊java了。
