关于模板类的定义和使用

Question

下面这个程序问题在哪里呢，昨天看了两个多小时都没成功
//模板类的定义
#include
using namespace std;
template
class ARRAY
{
public:
template
ARRAY(int _size)
{
this->size=_size;
p=new T[this->size];

}
    ~ARRAY(void)
{
    delete this->p;
}
template <typename T>
    T* Append(const ARRAY & other)const
{
    int i;
    T *p1;
    p1=new T[this->size+other.size];
    for(i=0;i<this->size;i++)
        p1[i]=this->p[i];
    for(int j=0;j<other.size;i++,j++)
        p1[i]=other.p[j];
    return p1;
}
template <typename T>
    T* operator+(const ARRAY & other)const
{
    int i;
    T *p1;
    p1=new T[this->size+other.size];
    for(i=0;i<this->size;i++)
        p1[i]=this->p[i];
    for(int j=0;j<other.size;i++,j++)
        p1[i]=other.p[j];
    return p1;
}
template <typename T>
    void setarray(void)
{
    int i;
    for(i=0;i<this->size;i++)
        cin>>this->p[i];
}

private:
int size;
T * p;
};
#include
#include"Append.h"
using namespace std;
void Print(double *p,int size)
{
for(int i=0;i cout }
//以下为main.cpp
#include
#include"Append.h"
using namespace std;
void Print(double *p,int size)
{
for(int i=0;i cout }
int main()
{
double *p;
ARRAY a(5);
ARRAY b(7);
a.setarray(void);
b.setarray(void);
p=a+b;
Print(p,12);
return 0;
}

执行 cl.exe 时出错.
13 14行那个构造函数到底错在哪了，我看了参数表列没问题啊
