我的错？书的错？还是我的编译器的错？

#include <iostream>
using namespace std;

template <typename T>
void showarr (T arr[] , int n);

template <typename T>
void showarr (T * arr[] , int n);

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

int main ()
{
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 << "things: \n";
showarr (things,6);
cout << "debts: \n";
showarr ( pd, 3); //A 处
return 0;
}



template <typename T>
void showarr (T arr[] , int n)
{

cout << "Template A \n";
for(int i = 0 ; i < n ; i++ )
cout << arr[i] << ' ';

}

template <typename T>
void showarr (T * arr[] , int n)
{

cout << "Template B\n";
for ( int i =0 ;i< n; i++)
cout << *arr [i] << ' ';
}
其实 这个是c++ primer Plus 上面的一个例子
我把我的程序和例子对照了 没有出入
但是编译时在A处提示错误 error C2667: 'addarr' : none of 2 overload have a best conversion
是书上面错了么？还是我写错了？还是编译器的问题？
我的是VC++6 SP6
请好心的大大们用30秒拿别的编译器编译一下 看能否通过。
70分全部奉上!

真想给自己一板砖

[clip49]

对VC6失望了 用起来真不爽！

[clip49]

经过 本人实验
把A处修改成 showarr<double> ( pd, 3);在我可怜的VC6上可以通过
但是根本不是我想要的那样的结果 本来只是一个验证摸板重载和谁更具体化问题
难道这是VC6的弊病？
]就象
string str;
getline(cin.str);
一样么？

编译没错哦

[珍惜生命远离CPP]

g++直接编译过去

[taodm]

就扔了你的VC6吧，不要浪费生命了。

things:
Template A

Error Message
'function' : none of number overloads have a best conversion


An overloaded function call is ambiguous and cannot be resolved.

The conversion required to match the actual parameters in the function call to one of the overloaded functions must be strictly better than the conversions required by all the other overloaded functions.

See Knowledge Base article Q240869 for more information on partial ordering of function templates.

vs2005看看！

error C2667: 'showarr' : none of 2 overload have a best conversion
的确如你所说改成showarr<double> ( pd, 3);就编译过去了
再看一下

G++吧，学C+＋就别用VC6了。

[hu_vane]

不要用VC6了，那东西对C＋＋标准的支持怎一个差字了得？
