實(shí)驗(yàn)五-運(yùn)算符重載--完成

1、精選優(yōu)質(zhì)文檔-傾情為你奉上 實(shí)驗(yàn)五 運(yùn)算符重載的應(yīng)用班級(jí)：B135A2學(xué)號(hào)： 姓名： 楊弘 成績(jī)： 一 實(shí)驗(yàn)?zāi)康?、理解運(yùn)算符重載的作用；2、掌握運(yùn)算符重載的兩種方法；3、掌握單目、雙目運(yùn)算符的重載；二 使用的設(shè)備和儀器計(jì)算機(jī)+Windows XP +Visual C+6.0三 實(shí)驗(yàn)內(nèi)容及要求1、定義一個(gè)復(fù)數(shù)類(lèi)Complex，重載運(yùn)算符“-”，使之能用于復(fù)數(shù)與實(shí)數(shù)的減法運(yùn)算。參加運(yùn)算的兩個(gè)操作數(shù)一個(gè)是類(lèi)的對(duì)象，一個(gè)是實(shí)數(shù)，順序任意。例如：i-c，c-i均合法（其中，c為復(fù)數(shù)類(lèi)的對(duì)象，i為實(shí)數(shù)）。減法規(guī)則：復(fù)數(shù)實(shí)部與實(shí)數(shù)相減，復(fù)數(shù)虛部不變。2、定義點(diǎn)類(lèi)Point，重載運(yùn)算符“”、“”、“”、“！

2、=”、“+”、“-”、“>>”、“<<”，實(shí)現(xiàn)兩個(gè)點(diǎn)的相加、相減、相等、不等、自增、自減、輸入和輸出運(yùn)算。3、定義一個(gè)矩陣類(lèi)Matrix，均為M行N列，通過(guò)重載運(yùn)算符“+”、“-”，“<<”,“>>”,“+”,“-”，“=”，“！=”來(lái)實(shí)現(xiàn)矩陣的相加、相減、輸出、輸入、自增、自減以及相等、不等的判斷。4、定義時(shí)間類(lèi)Time，時(shí)間的表示采用24小時(shí)制。重載運(yùn)算符“<<”和“>>”實(shí)現(xiàn)時(shí)間的輸出和輸入；重載運(yùn)算符“+”和“-”實(shí)現(xiàn)時(shí)間推后和提前若干分鐘；重載運(yùn)算符“+”和“-”實(shí)現(xiàn)當(dāng)前時(shí)間推后和提前1小時(shí)；重載“>”、“

3、<”、“=”來(lái)判斷兩個(gè)時(shí)間之間大于、小于、等于以及不等于的關(guān)系。注意：輸入時(shí)需對(duì)數(shù)據(jù)合法性進(jìn)行判斷。5、編寫(xiě)一個(gè)程序，處理一個(gè)復(fù)數(shù)與一個(gè)double型數(shù)相加的運(yùn)算，結(jié)果存放在一個(gè)double型的變量d1中，輸出d1的值，再以復(fù)數(shù)形式輸出此值。定義復(fù)數(shù)（Complex）類(lèi)，在成員函數(shù)中包含重載類(lèi)型轉(zhuǎn)換運(yùn)算符：Operator double（） return real；6、定義一個(gè)教師類(lèi)和一個(gè)學(xué)生類(lèi)，二者有一部分?jǐn)?shù)據(jù)成員是相同的，例如num，name，sex。請(qǐng)編程，將一個(gè)學(xué)生類(lèi)對(duì)象轉(zhuǎn)換為教師類(lèi)，只將以上3個(gè)相同的數(shù)據(jù)成員移植過(guò)去?？梢栽O(shè)想為：一位學(xué)生大學(xué)畢業(yè)了，留校擔(dān)任教師，他原有的部分?jǐn)?shù)

4、據(jù)對(duì)現(xiàn)在的教師身份來(lái)說(shuō)仍然是有用的，應(yīng)當(dāng)保留并成為其教師的數(shù)據(jù)的一部分。四 實(shí)驗(yàn)步驟1.程序代碼：/*1、定義一個(gè)復(fù)數(shù)類(lèi)Complex，重載運(yùn)算符"-"，使之能用于復(fù)數(shù)與實(shí)數(shù)的減法運(yùn)算。參加運(yùn)算的兩個(gè)操作數(shù)一個(gè)是類(lèi)的對(duì)象，一個(gè)是實(shí)數(shù)，順序任意。例如：i-c，c-i均合法（其中，c為復(fù)數(shù)類(lèi)的對(duì)象，i為實(shí)數(shù)）。減法規(guī)則：復(fù)數(shù)實(shí)部與實(shí)數(shù)相減，復(fù)數(shù)虛部不變。*/#include<iostream> /#include<iostream.h>using std:cin;using std:cout;using std:endl;/using namespace
