下面的代码不管是在VC6.0还是在VC2010上都是不通过，为什么啊，知道的说下：
听君一席话，胜读十年书
#include<iostream>
using namespace std;
template <typename T>
void swap(T &a,T &b);
struct KT
{
char name[40];
double xinshui;
int floor;
};
template <>void swap<KT>(KT &kt1,KT &kt2);
void show(KT &kt);
int main()
{
system ("color d");
int i=10,j=20;
cout<<"没用模板之前：\n";
cout<<"i="<<i<<",j="<<j<<endl;
swap(i,j);
cout<<"使用模板之后：\n";
cout<<"i="<<i<<",j="<<j<<endl;
KT mzx={"mazxiao",4324,56,3};
KT yys={"yyansheng",4200,78,5};
cout<<"没用模板之前：\n";
show(mzx);
show(yys);
cout<<"使用模板之后：\n";
show(mzx);
show(yys);
return 0;
}
template <typename T>
void swap(T &a,T &b)
{
T t;
t=a;
a=b;
b=t;
}
template <>void swap<KT>(KT &kt1,KT &kt2)
{
double t1;
int t2;
t1=kt1.xinshui;
kt1.xinshui=kt2.xinshui;
kt2.xinshui=t1;
t2=kt1.floor;
kt1.floor=kt2.floor;
kt2.floor=t2;
}
void show(KT &kt)
{
cout<<"姓名："<<kt.name<<endl;
cout<<"薪水："<<kt.xinshui<<endl;
cout<<"工作层："<<kt.floor<<endl;
}
