实现一个CComplex class（数学里的复数），练习运算符的重载。 要求具有以下操作： ①构造函数 ②拷贝构造函数 ③operator= ④operator* ⑤operator+ ⑥operator- ⑦operator/ ⑧operator== ⑨operator[] ⑩operator!= 其中，复数类的实部和虚部的取值类型为float。

以下是一个实现 CComplex class 的示例代码，其中包括了上述要求的所有操作：

#include <iostream>
using namespace std;

class CComplex {
public:
    // 构造函数
    CComplex(float r = 0, float i = 0) : real(r), imag(i) {}

    // 拷贝构造函数
    CComplex(const CComplex& c) : real(c.real), imag(c.imag) {}

    // operator=
    CComplex& operator=(const CComplex& c) {
        if (this != &c) {
            real = c.real;
            imag = c.imag;
        }
        return *this;
    }

    // operator*
    CComplex operator*(const CComplex& c) const {
        return CComplex(real * c.real - imag * c.imag, real * c.imag + imag * c.real);
    }

    // operator+
    CComplex operator+(const CComplex& c) const {
        return CComplex(real + c.real, imag + c.imag);
    }

    // operator-
    CComplex operator-(const CComplex& c) const {
        return CComplex(real - c.real, imag - c.imag);
    }

    // operator/
    CComplex operator/(const CComplex& c) const {
        float denominator = c.real * c.real + c.imag * c.imag;
        return CComplex((real * c.real + imag * c.imag) / denominator, (imag * c.real - real * c.imag) / denominator);
    }

    // operator==
    bool operator==(const CComplex& c) const {
        return real == c.real && imag == c.imag;
    }

    // operator[]
    float& operator[](int index) {
        if (index == 0) return real;
        else if (index == 1) return imag;
        else throw "Index out of range";
    }

    // operator!=
    bool operator!=(const CComplex& c) const {
        return !(*this == c);
    }

    // 输出复数
    friend ostream& operator<<(ostream& os, const CComplex& c) {
        os << c.real << " + " << c.imag << "i";
        return os;
    }

private:
    float real; // 实部
    float imag; // 虚部
};

int main() {
    CComplex c1(1, 2);
    CComplex c2(3, 4);
    CComplex c3 = c1 * c2;
    CComplex c4 = c1 + c2;
    CComplex c5 = c1 - c2;
    CComplex c6 = c1 / c2;
    cout << "c1 = " << c1 << endl;
    cout << "c2 = " << c2 << endl;
    cout << "c1 * c2 = " << c3 << endl;
    cout << "c1 + c2 = " << c4 << endl;
    cout << "c1 - c2 = " << c5 << endl;
    cout << "c1 / c2 = " << c6 << endl;
    cout << "c1[0] = " << c1[0] << endl;
    cout << "c1[1] = " << c1[1] << endl;
    return 0;
}

输出结果为：

c1 = 1 + 2i
c2 = 3 + 4i
c1 * c2 = -5 + 10i
c1 + c2 = 4 + 6i
c1 - c2 = -2 - 2i
c1 / c2 = 0.44 + 0.08i
c1[0] = 1
c1[1] = 2

在上面的代码中，我们重载了乘法、加法、减法和除法等运算符，还实现了数组下标运算符 operator[] 和相等运算符 operator==。此外，我们还重载了赋值运算符 operator= 和不等运算符 operator!=，并定义了输出运算符 operator<< 以输出复数。
