各位帮我看看错哪了，我想制作一个可以放入任何自定义类型和内置类型的数组

using namespace std;

template<class T>
class myarray
{
public:
    myarray(int capacity)
    {
        this->m_capacity = capacity;
        this->m_size = 0;
        this->paddress = new T(m_capacity);
    }
    myarray(const myarray& arr)
    {
        this->m_capacity = arr.m_capacity;
        this->m_size = arr.m_size;
        this->paddress = new T[arr.m_capacity];
        for (int i = 0; i < this->m_size; i++)
        {
            this->paddress[i] = arr.paddress[i];
        }
    }
    myarray& operator=(const myarray& arr)
    {
        if (paddress != NULL)
        {
            delete[] paddress;
            paddress = NULL;
            m_capacity = 0;
            m_size = 0;
        }
        m_capacity = arr.m_capacity;
        m_size = arr.m_size;
        paddress = new T(arr.m_capacity);
        for (int i = 0; i < this->m_size; i++)
        {
            paddress[i] = arr.paddress[i];
        }
        return *this;
    }
    ~myarray()
    {
        if (this->paddress != NULL)
        {
            delete[] this->paddress;
            this->paddress = NULL;
        }
    }
    void push_back(const T& val)
    {
        if (m_capacity == m_size)
        {
            return;
        }
        paddress[m_size] = val;
        m_size++;
    }
    void delete_back()
    {
        if (m_size == 0)
        {
            return;
        }
        m_size--;
    }
    T& operator[](int index)
    {
        return paddress[index];
    }
    int getcapacity()
    {
        return m_capacity;
    }
    int getsize()
    {
        return m_size;
    }
    void printmyarray()
    {
        for (int i = 0; i < m_size; i++)
        {
            cout << paddress[i] << " ";
        }
        cout << endl;
    }
private:
    T* paddress;
    int m_capacity;
    int m_size;
};

class person
{
private:
    string m_name;
    int height;
public:
    person()
    {
        m_name = "name"; height = 0;
    }
    person(string name, int a)
    {
        m_name = name;
        height = a;
    }
};

int main()
{
    myarray<int> arr(10);
    for (int i = 0; i < 10; i++)
    {
        arr[i] = i;
    }
    arr.printmyarray();
}
