1. 设计一个复数类CComplex (15分) 私
1、实验总设计图，这是一个清晰的 思路 概图，编程的时候也可以照着编写。
2、总设计方案
1.定义一个复数类以实现题目要求。
2.重载“+”“-”“<<”“>>”“=”“[]”运算符。
3.对友员函数进行定义实现复数的各种显示和运算，
4.设计主函数采用动态指针储存指定数量的复数信息，并可直接调用第“i”个。
3、1.运算符重载模块
主要完成功能为：实现复数的直接输入输出，相加相减，以及复数与实数的的相加相减并使其满足交换律。
主要使用技术：单目与双目运算符的重载
关键代码如下：
friend ostream& operator<<(ostream&, CComplex&);输入输出运算符重载
friend istream& operator>>(istream&, CComplex&);
friend CComplex operator +(const CComplex &c1, const CComplex &c2);加减运算符重载
friend CComplex operator -(const CComplex &c1, const CComplex &c2);
friend CComplex operator +(const CComplex &c1, const int a);
friend CComplex operator +(const int a, const CComplex &c1);
friend CComplex operator -(const CComplex &c1, const int a);
friend CComplex operator -(const int a, const CComplex &c1);
CComplex & operator=(CComplex &s1) 赋值运算符重载
4、2.信息存储模块
主要完成功能为：
实现复数的存储及直接调用。
主要使用技术：
动态指针存储技术
关键代码：
CComplex * sss = new CComplex[10]; // 采用指针存储动态数组方式存储n个复数信息
int i,k,j;
cout << "复数个数：";
cin >> j;
for (int x = 0; x < 1; x++)
{
cout << "存储复数信息,输入两个数";
for (i = 0; i < j; i++)
{
cin >> sss[i];
cout << sss[i];
}
cout << "直接输出第i个数"; cin >> k;直接调用
sss[0].display(sss, k);
}
return 0;
}
5、#include "stdafx.h"
#include<iostream>
using namespace std;
class CComplex
{
public:
CComplex(double r = 0, double i = 0)
{
real = r, image = i;
}
friend ostream& operator<<(ostream&, CComplex&);
friend istream& operator>>(istream&, CComplex&);
friend CComplex operator +(const CComplex &c1, const CComplex &c2);
friend CComplex operator -(const CComplex &c1, const CComplex &c2);
friend CComplex operator +(const CComplex &c1, const int a);
friend CComplex operator +(const int a, const CComplex &c1);
friend CComplex operator -(const CComplex &c1, const int a);
friend CComplex operator -(const int a, const CComplex &c1);
CComplex & operator=(CComplex &s1)
{
image = s1.image;
real = s1.real;
return *this;
}
6、CComplex operator[](int i)
{
return *this;
}
void display(CComplex *s1, int n) const
{
int i;
for (i =n-1; i < n; i++)
cout << s1[i].real << " " << "+" << " " << s1[i].image << "i" << endl;
}
void print();
private:
double real, image;
};
ostream& operator<<(ostream& os, CComplex& c)
{
if (c.image>0) os << c.real << '+' << c.image << 'i' << endl;
else if (c.image<0) os << c.real << c.image << 'i' << endl;
else os << c.real << endl;
return os;
}
istream& operator>>(istream& is, CComplex& c)
{
is >> c.real >> c.image;
return is;
}
void CComplex::print()
{
7、void CComplex::print()
{
if (image>0) cout << real << '+' << image << 'i' << endl;
else if (image<0) cout << real << image << 'i' << endl;
else cout << real << endl;
}
CComplex operator +(const CComplex &c1, const CComplex &c2)
{
return CComplex(c1.real + c2.real, c1.image + c2.image);
}
CComplex operator -(const CComplex &c1, const CComplex &c2)
{
return CComplex(c1.real - c2.real, c1.image - c2.image);
}
CComplex operator +(const CComplex &c1, const int a)
{
return CComplex(c1.real + a, c1.image + 0);
}
CComplex operator +(const int a, const CComplex &c1)
{
return CComplex(a + c1.real, 0 + c1.image);
}
CComplex operator -(const CComplex &c1, const int a)
{
return CComplex(c1.real - a, c1.image - 0);
}
CComplex operator -(const int a, const CComp
8、int _tmain(int argc, _TCHAR* argv[])

cout<<"c2="<<c2<<endl;

int i,k,j;
cout << "复数个数：";
cin >> j;
