调用类模板生成类函数时参数不匹配

Question

#include<iostream>
#include<stdlib.h>
using namespace std;
template< typename T >
class  Array
{
public:
    Array(int s);
    virtual ~Array();
    virtual const T& Entry(int index) const;
    virtual void Enter(int index, const T & value);
protected:
    int size;
    T * element;
};
template<typename T> Array<T>::Array(int s)
{
    if (s > 1) size = s;
    else size = 1;
    element = new T[size];
}
template < typename T > Array < T > :: ~Array()
{
    delete[] element;
}
template < typename T > const T& Array < T > ::Entry(int index) const
{
    return  element[index];
}
template < typename T > void Array < T > ::Enter(int index, const T& value)
{
    element[index] = value;
}
template < typename T >


class BoundArray : public Array < T >
{
public:
    BoundArray(int low = 0, int height = 1) :Array(height - low + 1)
    {
        if (height - low < 0)
        {
            cout << "Beyond the bounds of Array.\n";
            exit(1);
        }
        min = low;
    }
    virtual const T & Entry(int index) const
    {
        if (index < min || index > min + size - 1)
        {
            cout << "Beyond the bounds of index.\n";
            exit(1);
        }
        return Array<T>::Entry(index - min);
    }
    virtual void Enter(int index, const T& value)
    {
        if (index < min || index > min + size - 1)
        {
            cout << "Beyond the bounds of index.\n";
            exit(1);
        }
        Array<T>::Enter(index - min, value);
    }
protected:
    int min;
};


int main()
{
    int i;
    int low = 1, height = 10;
    BoundArray<int> b(low, height);
    for (i = low; i <= height; i++)
        b.Enter(i, i * 2);
    cout << "BoundArray: \n";
    for (i = low; i <= height; i++)
    {
        cout << "b[" << i << "] = " << b.Entry(i) << "\t";
        if (i % 5 == 0)cout << endl;
    }
}

哪位大神能帮忙看看应该怎么改吗
