【解決方法】分数の加算および乗算関数を実装するにはどうすればよいですか

 The function add for addition of fractions. The function’s parameter is an object of type 
Fraction, whose value will be added to the object’s current value. [Note: a/b + c/d = (
a*d + b*c)/b*d]
[5 marks]
e) The function multiply for multiplication of fractions. The function’s parameter  is  an 
object  of  type  Fraction,  whose  value  will  be multiplied by its current value. [Note: 
a/b * c/d = a*c/b*d]

私が試したこと：

void Fraction::add(Fraction f) {


}

まず、次のような分数の定義が必要です。

C++

class fract {
public:
	fract(): _counter(0), _divisor(1){}
	fract(int c, int d): _counter(c), _divisor(d){};
	fract& operator=(const fract& f) { /* TODO */ return *this;} // Assignment Operator
	fract& operator+=(const fract& f)  // compound assignment 
	{
		/* TODO: addition of f to *this takes place here */
		return *this; // return the result by reference
	}
	friend fract operator+(fract lhs, const fract& rhs) 
    { // Help for chained function a+b+c fractions
	   lhs += rhs; // use compound assignment
	   return lhs; // return result
    }
private:
	int _counter;
	int _divisor;
};

次に、分数を追加できます。

C++

int main()
{
	fract a(2, 3), b(1, 4), c;

	c = a + b;

	return 0;
}
