#include <iostream>
using namespace std;
template <class T>
class compare
{
public:
    compare(T x,T y):a(x),b(y){}
    T max();
private:
    T a;
    T b;
};
T compare::max()
{
    return (a>b)?a:b;
}
int main()
{
    compare<int> c1(3,7);
    cout<<c1.max()<<endl;
    compare<float> c2(4.4,3.2);
    cout<<c2.max()<<endl;
    return 0;
}

我实在是看不出什么错误来了，请高手解答一下哈
