【说明】 以下【C++程序】实现一个简单的小型复数类MiniComplex，该复数类能进行输入、输出、复数的加法、减法、乘法和除法运算，还可以进行复数的相等比较。【C++程序】#ifndef H_MiniComplex#define H_MiniComplex#include ＜iostream＞using namespace std;class MiniComplex{ public: //重载流插入和提取运算符 (1) ostream&operator＜＜(ostream &osObject,const MiniComplex&complex){ osObject＜＜"("＜＜complex.realPart＜＜"+"＜＜complex.imagPart＜＜"i"＜＜")"; return osObject; } (2) istream&operator＞＞(istream&isObject, MiniComplex&complex){ char ch; isObject ＞＞complex.realPart＞＞ch＞＞complex.imagPart＞＞ch; return isObject; } MiniComplex(double real=0,double imag=0); //构造函数 MiniComplex operator+(const MiniComplex&otherComplex)const; //重载运算符+ MiniComplex operator-(const MiniComplex&otherComplex)const; //重载运算符- MiniComplex operator*(const MiniComplex&otherComplex)const; //重载运算符* MiniComplex operator/(const MiniComplex&otherComplex)const; //重载运算符/ bool operator==(const MiniComplex&otherComplex)const; //重载运算符== private : double (3) ; double imagPart;};#end if#include "MiniComplex.h"bool MiniComplex::operator==(const MiniComplex&otherComplex)const{ return(realPart==otherComplex.realPart&&imagPart==ortherComplex.imagPart);}MiniComplex::MiniComplex(double real,double imag){ realPart== real;imagPart==imagPart;}MiniComplex MiniComplex::operator+(const MiniComplex&otherComplex)const{ MiniComplex temp; temp.realPart = realPart+ortherComplex. realPart; temp.imagPart = imagPart +ortherComplex. imagPart; return temp;} (4) { MiniComplex temp; temp.realPart= realPart-ortherComplex. realPart; temp.imagPart = imagPart-ortherComplex. imagPart; return temp;}MiniComplex MiniComplex::operator*(const MiniComplex&otherComplex)const{ MiniComplex temp; temp.realPart = (realPart*ortherComplex. realPart)-(imagPart *ortherComplex.imagPart); temp.imagPart = (realPart*ortherComplex. imagPart)+(imagPart *ortherComplex.realPart); return temp;}MiniComplex MiniComplex::operator/(const MiniComplex&otherComplex)const{ MiniComplex temp; float tt; tt=1/(ortherComplex.realPart*ortherComplex.realPart+ortherComplex.imagPart *ortherComplex. imagPart); temp.realPart=((realPart*ortherComplex, realPart)+(imagPart *ortherComplex. imagPart))*tt; temp.imagPart =((imagPart *ortherComplex. realPart)-(realPart*ortherComplex. imagPart))*tt; return temp;}#include ＜iostream＞#include ＜MiniComplex.h＞using namespace std;int main(){ MiniComplex numl(23, 34),num2(56, 35); cout＜＜"Initial Value of num1="＜＜num1＜＜"\n Initial Value of num2="＜＜num2＜＜end1; cout＜＜num1＜＜"+"＜＜num2＜＜"="＜＜num1+num2＜＜end1; //使用重载的加号运算符 cout＜＜num1＜＜"-"＜＜num2＜＜"="＜＜num1-num2＜＜end1; //使用重载的减号运算符 cout＜＜num1＜＜"*"＜＜num2＜＜"="＜＜num1*num2＜＜end1; //使用重载的乘号运算符 cout＜＜num1＜＜"/"＜＜num2＜＜"="＜＜num1/num2＜＜end1; //使用重载的除号运算符 (5) ;}
