簡(jiǎn)介：簡(jiǎn)答題簡(jiǎn)答題1、什么是面向?qū)ο笾械南⒁粭l消息由哪幾部分組成在面向?qū)ο蟪绦蛟O(shè)計(jì)中，消息是描述事件發(fā)生的信息，是對(duì)象之間發(fā)出的行為請(qǐng)求。事件一般由多個(gè)消息組成。在面向?qū)ο蠓椒ㄖ校⑹窍蚰硞€(gè)對(duì)象提出執(zhí)行該對(duì)象具有的特定服務(wù)的申請(qǐng)，不同對(duì)象之間通過發(fā)生消息向?qū)Ψ教岢龇?wù)請(qǐng)求，接受消息的對(duì)象主動(dòng)完成所請(qǐng)求的服務(wù)。通常一條消息由接受消息的對(duì)象、消息名稱和若干消息參數(shù)三部分組成。面向?qū)ο笾械南C(jī)制為不同對(duì)象之間提供了一個(gè)動(dòng)態(tài)聯(lián)系的途徑，使它們的行為能互相配合，構(gòu)成一個(gè)有機(jī)的運(yùn)行系統(tǒng)。2、什么是內(nèi)聯(lián)函數(shù)它具有哪些特點(diǎn)C程序中的內(nèi)聯(lián)函數(shù)是指由關(guān)鍵字INLINE定義的函數(shù)。對(duì)于內(nèi)聯(lián)函數(shù)，系統(tǒng)直接將函數(shù)體嵌入在發(fā)生內(nèi)聯(lián)函數(shù)的調(diào)用處，而不像普通函數(shù)調(diào)用一樣通過控制轉(zhuǎn)移執(zhí)行函數(shù)。對(duì)于一些功能比較簡(jiǎn)單、代碼少及使用頻率較高的函數(shù)，可以采用內(nèi)聯(lián)函數(shù)的方式，這樣比普通的函數(shù)調(diào)用節(jié)省了系統(tǒng)的開銷和運(yùn)行時(shí)間，提高了程序的執(zhí)行效率，其缺點(diǎn)是增大了系統(tǒng)空間方面的開銷。3、類定義中的公有成員、包含成員和私有成員各有何差別PUBLIC為類的外部接口，它定義了類的公有成員，可以被程序中任何代碼訪問；在類外，對(duì)類的任何訪問都需要通過該接口進(jìn)行。PRIVATE聲明了類的私有成員，凡需要實(shí)現(xiàn)信息隱蔽的成員可設(shè)置為PRIVATE訪問屬性，這種類型的成員只能被本類成員函數(shù)及友元訪問，其他函數(shù)無法訪問，成為一個(gè)外部無法訪問的黑盒子。設(shè)置為PROTECTED的成員稱為包含成員，只能被本類成員函數(shù)、派生類成員函數(shù)和又元訪問，其他函數(shù)無法訪問。保護(hù)成員與私有成員的訪問屬性類似，唯一差別在于該類在派生新類時(shí)，保護(hù)成員可以繼續(xù)繼承，而私有成員則不可以。4、構(gòu)造函數(shù)及析構(gòu)函數(shù)具有哪些功能各有何特點(diǎn)它們分別在何時(shí)執(zhí)行構(gòu)造函數(shù)是特殊的成員函數(shù)，它的功能是在定義對(duì)象時(shí)由編譯系統(tǒng)自動(dòng)調(diào)用來創(chuàng)建對(duì)象并初始化對(duì)象。C規(guī)定，如果程序員在類中沒有定義構(gòu)造函數(shù)，那么C編譯系統(tǒng)將自動(dòng)生成一個(gè)默認(rèn)形式的構(gòu)造函數(shù)，默認(rèn)構(gòu)造函數(shù)的功能僅用于創(chuàng)建對(duì)象。構(gòu)造函數(shù)除了具有一般默認(rèn)成員函數(shù)的特性之外，還有以下特點(diǎn)（1）構(gòu)造函數(shù)的函數(shù)名與類名相同（2）構(gòu)造函數(shù)可以有任意類型的參數(shù)，但沒有函數(shù)返回值類型（3）構(gòu)造函數(shù)一般被定義為公有成員（4）構(gòu)造函數(shù)在創(chuàng)建對(duì)象時(shí)由編譯系統(tǒng)自動(dòng)調(diào)用，其他任何過程都無法再調(diào)用它，即構(gòu)造函數(shù)只能一次性地影響對(duì)象的數(shù)據(jù)成員初值析構(gòu)函數(shù)的功能是，在對(duì)象生存期結(jié)束前進(jìn)行必要的清理工作，如釋放對(duì)象所占的內(nèi)存資源等析構(gòu)函數(shù)具有以下特點(diǎn)（1）析構(gòu)函數(shù)是類的特殊成員函數(shù)，它的名稱是在構(gòu)造函數(shù)名前加“”構(gòu)成，即在類名前加“”構(gòu)成析構(gòu)函數(shù)名。（2）析構(gòu)函數(shù)也沒有返回值類型，一般被定義為公有成員函數(shù)（3）析構(gòu)函數(shù)沒有參數(shù)，不能重載（4）析構(gòu)函數(shù)執(zhí)行結(jié)束之后，對(duì)象被刪除，對(duì)象所占用的存儲(chǔ)單元被釋放由STATIC關(guān)鍵字限定的數(shù)據(jù)成員稱為靜態(tài)數(shù)據(jù)成員。對(duì)于類的普通數(shù)據(jù)成員，每一個(gè)對(duì)象都各自擁有一個(gè)副本，即每個(gè)對(duì)象的同名數(shù)據(jù)成員可以分別存儲(chǔ)不同的值。但是，由于靜態(tài)數(shù)據(jù)成員，每個(gè)類只擁有一個(gè)副本，從而實(shí)現(xiàn)了同一個(gè)類的不同對(duì)象之間的數(shù)據(jù)共享。特點(diǎn)（1）靜態(tài)成員的初始化是在編譯時(shí)進(jìn)行的（2）靜態(tài)數(shù)據(jù)成員不專屬于某一個(gè)對(duì)象，而是整個(gè)類的數(shù)據(jù)成員，不能用構(gòu)造函數(shù)進(jìn)行初始化，因此靜態(tài)數(shù)據(jù)成員必須單獨(dú)進(jìn)行初始化（3）程序開始運(yùn)行時(shí)靜態(tài)數(shù)據(jù)成員必須存在，直到程序運(yùn)行結(jié)束時(shí)才消除數(shù)據(jù)成員，靜態(tài)數(shù)據(jù)成員不能再任何函數(shù)內(nèi)分配存儲(chǔ)空間和初始化（4）靜態(tài)數(shù)據(jù)成員的初始化與一般數(shù)據(jù)成員的初始化有所不同，其初始化方法如下類型類名靜態(tài)數(shù)據(jù)成員初始化值
