.....抱歉....

哥，你有多马虎啊？

#include<iostream>

 using namespace std;

 template <typename T>

 T max(T a,T b,T c)

 {
     if(b>a) a=b;

 if(c>a) a=c;

 return a;

}

 int main()

 {int i1=8,i2=5,i3=6,i;

 double d1=56.9,d2=90.765,d3=43.1,d;

 long g1=678984,g2=-1245,g3=-45461,g;

 i=max(i1,i2,i3);

 d=max(d1,d2,d3);

 g=max(g1,g2,g3);

 cout << "i_max="<<i<<endl;

 cout <<"d_max="<<d<<endl;

 cout <<"g_max="<<g<<endl;


    return 0;

 }

目的是什么？
