使用【c++】写本实验利用C++面向对象的编程知识设计一个特殊的计算器，可以实现复数、有理数、矩阵的特殊计算。其中复数运算实现复数的加法、减法、乘法和除法的基本功能；矩阵运算实现矩阵的加法、减法和乘法的基本功能；有理数运算实现有理数的加法、减法和乘法的基本功能。代码

在C++中设计这样一个特殊的计算器，首先需要创建三个类分别表示复数、有理数和矩阵，并提供相应的操作函数。这里是一个简化的实现示例：

#include <iostream>
#include <vector>

// 定义复数类 Complex
class Complex {
public:
    double real;
    double imag;

    // 构造函数
    Complex(double r = 0, double i = 0) : real(r), imag(i) {}

    // 加法
    Complex operator+(const Complex& other) const {
        return Complex(real + other.real, imag + other.imag);
    }

    // 减法
    Complex operator-(const Complex& other) const {
        return Complex(real - other.real, imag - other.imag);
    }

    // 乘法
    Complex operator*(const Complex& other) const {
        double new_real = real * other.real - imag * other.imag;
        double new_imag = real * other.imag + imag * other.real;
        return Complex(new_real, new_imag);
    }

    // 除法，注意除以零的情况
    Complex operator/(const Complex& other) const {
        if (other.imag == 0 && other.real != 0)
            throw std::runtime_error("Division by zero is not allowed");
        double denominator = other.real * other.real + other.imag * other.imag;
        double new_real = (real * other.real + imag * other.imag) / denominator;
        double new_imag = (imag * other.real - real * other.imag) / denominator;
        return Complex(new_real, new_imag);
    }
};

// 有理数类 Rational
class Rational {
private:
    int numerator;
    int denominator;

public:
    // 构造函数
    Rational(int num = 0, int den = 1) : numerator(num), denominator(den) {}

    // ... 类似复数的加、减、乘函数

    // 乘法，保持分母不变
    Rational operator*(const Rational& other) const {
        int new_num = numerator * other.numerator;
        return Rational(new_num, denominator);
    }

    // 其他操作同理
};

// 矩阵类 Matrix
class Matrix {
private:
    std::vector<std::vector<int>> data;

public:
    // 构造函数
    Matrix(std::vector<int> row_data) : data(row_data) {}

    // 加法和减法
    Matrix operator+(const Matrix& other) const {
        Matrix result(data.size(), data[0].size());
        for (int i = 0; i < data.size(); ++i) {
            for (int j = 0; j < data[i].size(); ++j) {
                result.data[i][j] = data[i][j] + other.data[i][j];
            }
        }
        return result;
    }

    // 乘法，假设输入矩阵是方阵
    Matrix operator*(const Matrix& other) const {
        Matrix result(other.columns(), data.size());
        for (int i = 0; i < result.rows(); ++i) {
            for (int j = 0; j < other.columns(); ++j) {
                int sum = 0;
                for (int k = 0; k < data.columns(); ++k) {
                    sum += data[i][k] * other.data[k][j];
                }
                result.data[i][j] = sum;
            }
        }
        return result;
    }
};

// 示例如何使用
int main() {
    Complex c1(1, 2);
    Complex c2(3, 4);
    std::cout << "Complex addition: " << c1 + c2 << std::endl;

    Rational r1(2, 3);
    Rational r2(4, 5);
    std::cout << "Rational multiplication: " << r1 * r2 << std::endl;

    Matrix m1({1, 2, 3}, {4, 5, 6});
    Matrix m2({7, 8, 9}, {10, 11, 12});
    std::cout << "Matrix addition: " << m1 + m2 << std::endl;

    return 0;
}

这个示例展示了基本的复数、有理数和矩阵类的设计以及一些基本操作。实际项目中，你需要添加更多的错误处理和验证功能。
