用c++实现带有定义整数类和分数类的分数计算器

好的，我可以为您提供一些基本的代码实现。首先，我们需要定义整数类和分数类。

class Integer {
private:
    int num;
public:
    Integer(int n) : num(n) {}
    Integer operator+(const Integer& other) const {
        return Integer(num + other.num);
    }
    Integer operator-(const Integer& other) const {
        return Integer(num - other.num);
    }
    Integer operator*(const Integer& other) const {
        return Integer(num * other.num);
    }
    Integer operator/(const Integer& other) const {
        return Integer(num / other.num);
    }
    int getNum() const { return num; }
};

class Fraction {
private:
    int numerator;
    int denominator;
public:
    Fraction(int n, int d) : numerator(n), denominator(d) {}
    Fraction operator+(const Fraction& other) const {
        int lcm = denominator * other.denominator / gcd(denominator, other.denominator);
        int num = numerator * lcm / denominator + other.numerator * lcm / other.denominator;
        return Fraction(num, lcm);
    }
    Fraction operator-(const Fraction& other) const {
        int lcm = denominator * other.denominator / gcd(denominator, other.denominator);
        int num = numerator * lcm / denominator - other.numerator * lcm / other.denominator;
        return Fraction(num, lcm);
    }
    Fraction operator*(const Fraction& other) const {
        return Fraction(numerator * other.numerator, denominator * other.denominator);
    }
    Fraction operator/(const Fraction& other) const {
        return Fraction(numerator * other.denominator, denominator * other.numerator);
    }
    int getNumerator() const { return numerator; }
    int getDenominator() const { return denominator; }
    void simplify() {
        int g = gcd(numerator, denominator);
        numerator /= g;
        denominator /= g;
    }
    int gcd(int a, int b) {
        return b == 0 ? a : gcd(b, a % b);
    }
};

然后我们可以实现一个简单的分数计算器，接受用户输入两个分数和一个操作符，然后计算出结果并输出。

int main() {
    int num1, den1, num2, den2;
    char op;
    cout << "Please enter two fractions and an operator (+, -, *, /): ";
    cin >> num1 >> den1 >> op >> num2 >> den2;
    Fraction frac1(num1, den1);
    Fraction frac2(num2, den2);
    Fraction result;
    switch (op) {
    case '+':
        result = frac1 + frac2;
        break;
    case '-':
        result = frac1 - frac2;
        break;
    case '*':
        result = frac1 * frac2;
        break;
    case '/':
        result = frac1 / frac2;
        break;
    default:
        cout << "Invalid operator!\n";
        return 1;
    }
    result.simplify();
    cout << "Result: " << result.getNumerator() << "/" << result.getDenominator() << endl;
    return 0;
}

这就是一个简单的基于C++的分数计算器的实现。当然，这只是一个简单的示例，您可以根据您的需求进行更多的扩展和改进。
