cursescurses在gcc下该怎么编译？

python urwid和curses哪个好

完全可以的。

Python、Perl、Tcl都有各自的Socket库，至于Ruby和Lua，我不熟。

不过，我可以肯定，Python、Perl、Tcl都可以做到。

Shell也可以实现，不过要借助各种软件工具，你应该听说过Shell实现Curses库的功能吧，实现Socket也不是没有可能。

总之一句话，建议用Python、Perl和Tcl解决。

shout to sb.与shout at sb. 有什么区别吗？

有。

shout to sb.是为了让那人听到或听清而喊。

shout at sb.是因为生气等而非善意地向那人吼，带有攻击性。

at经常有这种用法。

如： throw a stone to sb. 扔一块石头让某人接着；throw a stone at sb. 用一块石头向某人砸去。

laugh to sb. 对某人大笑（善意地）；laugh at sb. 嘲笑某人

告诉我neither的用法

ording to the traditional rule, neither is used only to mean “not one or the other of two.” To refer to “none of several,” none is preferred: 按传统规则，neither 只用于表示“不是这个也不是另一个”。

要指“多个中一个也没有”时最好用none ： None (not neither ) of the three opposition candidates would make a better president than the incumbent. · 三位反对党总统候选人中的任何一个 （不用 neither ) 都比在任者强。

· The traditional rule holds that either should be used only to refer to one of two items and that any is required when more than two items are involved: 传统规则认为either 只能用于指两者之一， 如果涉及多于两者的情况时，应用any ： Any (not either ) of the three opposition candidates still in the race would make a better president than the incumbent. 正在参加竞选的三个反对党候选人中的任何 （不是 either ) 一个都会比现任总统干得更好。

But reputable writers have often violated this rule, and in any case it applies only to the use of either as a pronoun or an adjective. When either is used as a conjunction no paraphrase with any is available, and so either is unexceptionable even when it applies to more than two clauses: 但是许多著名作家经常违反这个规则，这种情况只见于either 用作代名词或形容词时。

当either 用作连接词时， any 没有相应的替代词， 所以即使用来连接多于两个从句时，也要用either ： Either the union will make a counteroffer or the original bid will be refused by the board or the deal will go ahead as scheduled. · 或者工会提出一个相反的建议，或者董事会拒绝原来的要价，或者这事按原计划进行。

In either . . . or constructions, the two conjunctions should be followed by parallel elements. The following is regarded as incorrect: You may either have the ring or the bracelet (properly, You may have either the ring or the bracelet ). The following is also incorrect: She can take either the examination offered to all applicants or ask for a personal interview (properly, She can either take . . . ). · When used as a pronoun, either is singular and takes a singular verb: The two left-wing parties disagree with each other more than either does (not do ) with the right. When followed by of and a plural noun, either is often used with a plural verb: 在either … or 结构中， 两个连接词后应跟并列成分。

下面这句话被认为是不正确的：You may either have the ring or the bracelet ，正确的应是 You may have either the ring or the bracelet （你既可以有戒指也可以有手镯） 下面这句也是不对的：She can take either the examination offered to all applicants or ask for a personal interview。

正确的应是， She can either take …（她可以参加提供给所有申请人的考试，也可以要求一个单独面试。

） 作为代名词时，either 是单数，动词应用单数形式： The two left-wing parties disagree with each other more than either does （不用 do ) with the right.（两个左翼党之间的分歧比任何一个与右翼党的分歧都要大） 当后面接of 和一个复数名词的时候， either 经常与动词复数形式配合： Either of the parties have enough support to form a government. 这些政党中任一个都有足够的支持来组阁一个政府。

But this usage is widely regarded as incorrect; in an earlier survey it was rejected by 92 percent of the Usage Panel. · When all the elements in an either . . . or construction (or a neither . . . nor construction) used as the subject of a sentence are singular, the verb is singular: 但是这种用法通常被认为是不正确的，在以前的调查中它被用法使用小组百分之九十二的成员所否定。

当作为句中主语的either…or 结构（或 neither…nor 结构）中的所有成分都是单数的时候， 动词也应用单数： Either Eve or Herb has been invited. 伊夫和赫伯都被 邀请了。

Analogously, when all the elements in the either . . . or construction are plural, the verb is plural too: 类似地，当所有either…or 结构中的成分都是复数的时候， 动词也应用复数： Either the Clarks or the Kays have been invited. 克拉克全家和凯全家都被 邀请了。

When the construction mixes singular and plural elements, however, there is some confusion as to which form the verb should take. It has sometimes been suggested that the verb should agree with whichever noun phrase is closest to it; thus one would write Either Eve or the Kays have been invited, but Either the Kays or Eve has been invited. This pattern is epted by 54 percent of the Usage Panel. Others have maintained that the construction is fundamentally inconsistent whichever number is assigned to the verb and that such sentences should be rewritten ordingly. As Wilson Follett put it: 然而，当结构中既有单数又有复数成分的时候，动词应采取什么形式说法不定。

人们有时建议动词的人称和数应与离得最近的名词短语呼应；因此人们说Either Eve or the Kays have been invited ， 而不是Either the Kays or Eve has been invited 。

这种格式被用法使用小组54的成员所接受。

也有人认为不管动词用什么样的数， 这个结构本质上都是一致的，因此这样的句子应重写。

象威尔逊·伏莱特所说的： “This [construction] is defensible, but a workmanlike writer may put his pride in not writing sentences that need defending.”See Usage Note at every, neither, or 1 “这个是站得住脚的，但是精心推敲的作者应以写出不需为之辩护的句子而感到骄傲。

”参见 every， neither， or1 The traditional rule also holds that neither is grammatically singular: 传统规则还认为neither 在语法上是单数： Neither candidate is having an easy time with the press. 每一位候选人都被记者百般纠缠。

However, it is often used with a plural verb, especially when followed by of and a plural: 但它常跟复数动词连用，尤其当后跟of 和一个复数名词时： Neither of the candidates are really expressing their own views. · 没有一位候选人真实地表达出他们的观点。

· As a conjunction neither is properly followed by nor, not or, in formal style: 作为一个连词，在正式文体中neither 后宜跟 nor 而不是 or ： Neither prayers nor curses (not or curses ) did any good. See Usage Note at either, every, he 1none, nor 1or 1 祈祷和咒语（而不用 or curses ) 都不会起任何作用 参见 either， every， he1none， nor1or1

curses在gcc下该怎么编译？

你用的是windows还是linux，有没有安装ncurses包呢？ 如果是linux的话请安装 “libncurses5-dev” 编译参数是 “ file.c -lncurses” 没有错。
