C++中函数模板显示具体化问题大家快来看看啊~（已解决）

#include<iostream>
using namespace std;

template <class T>
void ShowArray(T arr[],int n);



struct debts
{
    char name[50];
    double amount;
};


template <> void ShowArray<char *>(char * arr[],int n);

int main(void)
{
    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 counts of things: \n";

    ShowArray(things,6);

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

        ShowArray(pd,3);//有错
        return 0;
}

template <class T>
void ShowArray(T arr[],int n)
{
    T sum=0;
    cout<<"template A\n";
    for(int i=0;i<n;i++)
        sum=sum+arr[i];//1有错
    cout<<"Sum things are "<<sum<<endl<<endl;
}

template <> void ShowArray<char *>(char * arr[],int n)
{
    double sum=0;
        cout<<"template B\n";
            for(int i=0;i<n;i++)
        sum=sum+*arr[i];
            cout<<"Sum debts are "<<sum<<endl<<endl;
}



        

请帮我把程序改正确，能够指点一下更加感谢啊~

显式具体化templete<type>
如templete<int>
