给定分数类MyRational,该类包括两个整型数据 成员numerator和denominator,分别表示分数的分子 和分母。请编写两个函数分别重载和/运算符,实现 两个分数的乘法和除法,并按双精度浮点数的形式输 出两个分数相乘或相除的结果。函数原型为: double operator(MyRational& r); double operator/(MyRational& r); 例如对分数a = 123/235, b = 87/35, 则: a * b = 1.30103 a / b = 0.210565

可以按照以下方式重载乘法运算符和除法运算符来实现两个分数的乘法和除法:
```cpp
#include <iostream>
class MyRational {
private:
int numerator;
int denominator;
public:
MyRational(int num, int denom) : numerator(num), denominator(denom) {}
double operator*(MyRational& r) {
return static_cast<double>(numerator * r.numerator) / (denominator * r.denominator);
}
double operator/(MyRational& r) {
return static_cast<double>(numerator * r.denominator) / (denominator * r.numerator);
}
};
int main() {
MyRational a(123, 235);
MyRational b(87, 35);
double product = a * b;
double quotient = a / b;
std::cout << "a * b = " << product << std::endl;
std::cout << "a / b = " << quotient << std::endl;
return 0;
}
```
运行以上代码,将输出:
```
a * b = 1.30103
a / b = 0.210565
```
这样就实现了两个分数的乘法和除法,并以双精度浮点数的形式输出结果。
