LINK : fatal error LNK1561: entry point must be defined

我用vs2005
出现上面错误
这是代码，看不出哪里有错误啊。



#include <iostream>



template <typename T>

T showarray(T arr[],int n);



template <typename T>

T showarray(T *arr[],int n);



struct debts

{

	char name[50];

	double amount;

};

int mian()

{

	using namespace std;

	int things[6]={13,31,103,301,310,130};

	struct debts mr_e[3]=

	{

		{"Ima Wolfe",2400.0},

		{"Ura Foxe",1300.0},

		{"Iby Stout",1800.0}

	};

	double *pd[3];



	for(int i=0;i<3;i++)

		pd[i]=&mr_e[i].amount;



	cout<<"Listing Mr.E's couts of things: \n";

	cout<<"total"<<showarray(things,6); //use templateA

	cout<<"Listing Mr.E's debts: \n";

	cout<<"total"<<showarray(pd,3);//tamplateB

	return 0;

}



template <typename T>

T showarray(T arr[],int n)

{

	using namespace std;

	cout<<"template A\n";

	T total=0;

	for(int i=0;i<n;i++)

		total=total+arr[i];

	return total;

}

template <typename T>

T showarray(T *arr[],int n)

{

	using namespace std;

	cout<<"template B\n";

	T total=0;

	for(int i=0;i<n;i++)

		total=total+ *arr[i];

	return total;

}
