分数的运算符重载，用 c++编写

好的，下面是分数的运算符重载代码：

#include <stdio.h>

//定义分数类型
typedef struct Fraction {
    int numerator;   //分子
    int denominator; //分母
}fraction;

//计算最大公约数
int gcd(int a, int b) {
    if (a % b == 0) {
        return b;
    } else {
        return gcd(b, a % b);
    }
}

//分数化简
void reduction(fraction *f) {
    int commonDivisor = gcd(f->numerator, f->denominator);
    f->numerator /= commonDivisor;
    f->denominator /= commonDivisor;
}

//分数相加
fraction operator+(fraction f1, fraction f2) {
    fraction sum;
    sum.numerator = f1.numerator*f2.denominator + f2.numerator*f1.denominator;
    sum.denominator = f1.denominator*f2.denominator;
    reduction(&sum);
    return sum;
}

//分数相减
fraction operator-(fraction f1, fraction f2) {
    fraction difference;
    difference.numerator = f1.numerator*f2.denominator - f2.numerator*f1.denominator;
    difference.denominator = f1.denominator*f2.denominator;
    reduction(&difference);
    return difference;
}

//分数相乘
fraction operator*(fraction f1, fraction f2) {
    fraction product;
    product.numerator = f1.numerator*f2.numerator;
    product.denominator = f1.denominator*f2.denominator;
    reduction(&product);
    return product;
}

//分数相除
fraction operator/(fraction f1, fraction f2) {
    fraction quotient;
    quotient.numerator = f1.numerator*f2.denominator;
    quotient.denominator = f1.denominator*f2.numerator;
    reduction(&quotient);
    return quotient;
}

//输出分数
void printFraction(fraction f) {
    printf("%d/%d\n", f.numerator, f.denominator);
}

int main() {
    fraction f1 = {3, 4};
    fraction f2 = {1, 2};
    
    fraction sum = f1 + f2;
    printf("f1+f2=");
    printFraction(sum);
    
    fraction difference = f1 - f2;
    printf("f1-f2=");
    printFraction(difference);
    
    fraction product = f1 * f2;
    printf("f1*f2=");
    printFraction(product);
    
    fraction quotient = f1 / f2;
    printf("f1/f2=");
    printFraction(quotient);
    
    return 0;
}

希望能对你有所帮
