错误：

error C2784: 'Type __cdecl min(Type (&)[1])' : could not deduce template argument for ' (&)[1]' from 'int [5]'

怎么感觉是摸板写错了，改了一下，你看看是不是你想要的结果，
#pragma warning(disable:4305)
#include<iostream>
using namespace std;
template<typename Type>
Type min(Type *r_array,int size)
{
Type min_val=r_array[0];
for(int i=1;i<size;i++)
if(r_array[i]<min_val)
min_val=r_array[i];

return min_val;
}
int main()
{
float f[10]={0.3,0.2,0.1,0.4,1.0,0.5,0.6,0.7,0.8,0.9};
int n[5]={1,5,2,3,4};
cout<<min(n,5);
return 0;
}

能在不改变我的接口情况下实现么？

那可以的
#pragma warning(disable:4305)
#include<iostream>
using namespace std;
template<typename Type>
Type min(Type *r_array)
{
Type min_val=r_array[0];
for(int i=1;i<(sizeof(r_array)/sizeof(*r_array));i++)//第二个表达式的左边是求数组个数
if(r_array[i]<min_val)
min_val=r_array[i];

return min_val;
}
int main()
{
float f[10]={0.3,0.2,0.1,0.4,1.0,0.5,0.6,0.7,0.8,0.9};
int n[5]={1,5,2,3,4};
cout<<min(n);
return 0;
}
