Sum函数模板不适用于我的Fraction类

Question

我做了分数和模板函数Sum类，应该将分数数组求和。但是当我尝试执行此功能时它说这是错误的类型 （不允许输入类型名称）。

class Fraction{
public:
    int numerator;
    unsigned denominator;

    Fraction() {};
    Fraction(int nume, unsigned denom = 1);
    Fraction operator += (const Fraction &u);
};

Fraction::Fraction(int nume, unsigned denom)
{
    numerator = nume;
    denominator = denom;
}

Fraction Fraction::operator += (const Fraction &u)
{
    int a, b, product, LCM; //least common multiple
    a = denominator;
    b = u.denominator;
    product = a*b;

    do
    {
        if (a > b) a = a - b;
        else b = b - a;
    } while (a != b);

    LCM = product / a;

    numerator = (LCM / denominator)*numerator + (LCM / u.denominator)*u.numerator;
    denominator = LCM;

    return *this;

}

template <class T>
T Summ(int count, T *array)
{
    T sum = 0;

    for (int i = 0; i < count; i++)
        sum += array[i];

    return sum;
}

主要

cout << Summ(2, Fraction) << endl;

我不想更改Summ函数。 我想要分数数组

Fraction *tab = new Fraction[2];
    tab[0] = Fraction(2, 4);
    tab[1] = Fraction(5, 6);

，然后求和。 类似于

int ints[8]  = {1,2,3,4,-5,6,-12,16};
cout << Summ(8, ints) << endl;
