用c＋＋编写分数的运算符重载完整的程序 包括主函数

好的，请稍等一下，让我思考一下。

以下是用c＋＋编写分数的运算符重载的完整程序，包括主函数。您可以参考一下：

#include <iostream>
using namespace std;

class Fraction {
private:
    int numerator; // 分子
    int denominator; // 分母

public:
    Fraction(int num = 0, int den = 1) {
        numerator = num;
        denominator = den;
        while (denominator == 0) {
            cout << "分母不能为0，请重新输入！" << endl;
            cout << "分子：" << endl;
            cin >> numerator;
            cout << "分母：" << endl;
            cin >> denominator;
        }
        reduce();
    }

    void reduce() { // 约分
        int sign = 1;
        if (numerator < 0)
            sign = -sign;
        if (denominator < 0)
            sign = -sign;
        int n = abs(numerator), d = abs(denominator);
        int gcd = 1;
        for (int i = 1; i <= n && i <= d; i++)
            if (n % i == 0 && d % i == 0)
                gcd = i;
        numerator = sign * (numerator / gcd);
        denominator = abs(denominator / gcd);
    }

    Fraction operator +(const Fraction& f) const { // 加法重载
        Fraction res;
        res.denominator = denominator * f.denominator;
        res.numerator = numerator * f.denominator + f.numerator * denominator;
        res.reduce();
        return res;
    }

    Fraction operator -(const Fraction& f) const { // 减法重载
        Fraction res;
        res.denominator = denominator * f.denominator;
        res.numerator = numerator * f.denominator - f.numerator * denominator;
        res.reduce();
        return res;
    }

    Fraction operator *(const Fraction& f) const { // 乘法重载
        Fraction res;
        res.numerator = numerator * f.numerator;
        res.denominator = denominator * f.denominator;
        res.reduce();
        return res;
    }

    Fraction operator /(const Fraction& f) const { // 除法重载
        Fraction res;
        res.numerator = numerator * f.denominator;
        res.denominator = denominator * f.numerator;
        res.reduce();
        return res;
    }

    friend ostream& operator <<(ostream& os, const Fraction& f) { // 输出重载
        os << f.numerator << "/" << f.denominator;
        return os;
    }

};

int main() {
    int num1, den1, num2, den2;
    cout << "请输入第一个分数的分子：" << endl;
    cin >> num1;
    cout << "请输入第一个分数的分母：" << endl;
    cin >> den1;
    cout << "请输入第二个分数的分子：" << endl;
    cin >> num2;
    cout << "请输入第二个分数的分母：" << endl;
    cin >> den2;

    Fraction f1(num1, den1);
    Fraction f2(num2, den2);

    cout << "加法结果为：" << f1 + f2 << endl;
    cout << "减法结果为：" << f1 - f2 << endl;
    cout << "乘法结果为：" << f1 * f2 << endl;
    cout << "除法结果为：" << f1 / f2 << endl;

    return 0;
}

希望这个程序对您有所帮助！
