第九次实验报告

学生实验报告一、实验综述1、实验目的及要求1. 根据PPT改善复数类，增加重载的运算符：-、-=、*=、/=和++，实现完整的复数的加减乘除等运算并定义main 函数检测之。

2. 完成下列类的定义，并为其添加一个重载的赋值语句，即定义person p1,p2后，能实现p2=p1，主函数已经给出要求。

#include <iostream>#include <string>using namespace std;class person{char *Name;int Age;char Sex;public:person(char * name="JACK", int age=10, char sex='F');~person();char *GetName(){return Name;}int GetAge(){return Age;}char GetSex(){return Sex;}void show();};void main(){//即完成以下操作，使得p1和p2的内容一致。

person p1("Jack", 12, 'f');p1.show();person p2;p2=p1;p2.show();}2、实验仪器、设备或软件二、实验过程（实验步骤、记录、数据、分析）1、/*This program is designed to achieve the operation of complex,it includes +,-,*,/,-,-=,*=,/= and ++.*/ #include <iostream.h>class complex{public:complex(double r=0,double i=0);friend complex operator +(const complex& c1,const complex& c2); //+operationfriend complex operator -(const complex& c1,const complex& c2); //- operationfriend complex operator *(const complex& c1,const complex& c2); //* operationfriend complex operator /(const complex& c1,const complex& c2); // / operationcomplex operator -(); //negative operation complex operator -=(const complex& c); //-= operationcomplex operator *=(const complex& c); //*= operationcomplex operator /=(const complex& c); // /=operationcomplex operator ++(); //++ operationvoid print() const;private:double real,imag;};complex::complex(double r,double i){real=r;imag=i;}complex operator +(const complex& c1,const complex& c2) //+operation{double r=c1.real+c2.real;double i=c1.imag+c2.imag;return complex(r,i);}complex operator -(const complex& c1,const complex& c2) //- operation{double r=c1.real-c2.real;double i=c1.imag-c2.imag;return complex(r,i);}complex operator *(const complex& c1,const complex& c2) //* operation{double r=c1.real*c2.real-c1.imag*c2.imag;double i=c1.real*c2.imag-c1.imag*c2.real;return complex(r,i);}complex operator /(const complex& c1,const complex& c2) // / operation{double r=(c1.real*c2.real+c1.imag*c2.imag)/(c2.real*c2.real+c2.imag*c2.imag);double i=(c1.imag*c2.real-c1.real*c2.imag)/(c2.real*c2.real+c2.imag*c2.imag);return complex(r,i);}complex complex::operator -() //negative operation{return complex(-real,-imag);}complex complex::operator -=(const complex& c) //-= operation{double r=real-c.real;double i=imag-c.imag;return complex(r,i);}complex complex::operator *=(const complex& c) //*= operation {double r=real*c.real-imag*c.imag;double i=real*c.imag-imag*c.real;return complex(r,i);}complex complex::operator /=(const complex& c) // /= operation {double r=(real*c.real+imag*c.imag)/(c.real*c.real+c.imag*c.imag);double i=(imag*c.real-real*c.imag)/(c.real*c.real+c.imag*c.imag);return complex(r,i);}complex complex::operator ++() //++ operation {return complex(real+real,imag+imag);}void complex::print() const{cout<<"("<<real<<","<<imag<<")"<<endl;}void main(){complex c1(2.5,3.7),c2(4.2,6.5);complex c;c=c1-c2;c.print();c=c1+c2;c.print();c=c1*c2;c.print();c=c1/c2;c.print();c=-c1;c.print();c=c1-=c2;c.print();c=c1*=c2;c.print();c=c1/=c2;c.print();c=c1++;c.print();}2、/*This program is designed to translate the information of the class from one object to anthor.*/ #include<iostream>#include<string>using namespace std;class person{char *Name;int Age;char Sex;public:person(char * name="JACK", int age=10, char sex='F');person &operator =(const person &p);~person();char *GetName(){return Name;}int GetAge(){return Age;}char GetSex(){return Sex;}void show();};person::person(char *name,int age ,char sex){Age=age;Sex=sex;Name=new char[strlen(name)+1];strcpy(Name,name);}person &person::operator =(const person &p){Name=new char[strlen()+1];strcpy(Name,);this->Age=p.Age;this->Sex=p.Sex;return *this;}person::~person(){delete []Name;}void person::show(){cout<<"Name:"<<Name<<'\t'<<"Sex:"<<Sex<<'\t'<<"Age:"<<Age<<endl; }void main(){//即完成以下操作，使得p1和p2的内容一致。
