C++类模板的基础应用

#include<iostream>
using namespace std;
template<class haha>
class Compare {
private:
  haha x, y;
public:
  Compare(haha a, haha b) {
    x = a;
    y = b;
  }
  haha max() {
    return (x > y) ? x : y;
  }
  haha min() {
    return (x > y) ? y : x;
  }
};
int main()
{
  Compare <int>c(1, 2);
  cout << "max=" << c.max() << endl << "min=" << c.min() << endl;
  Compare <float>d(1.1, 2.2);
  cout << "max=" << d.max() << endl << "min=" << d.min() << endl;
  Compare <char>e('a', 'A');
  cout << "max=" << e.max() << endl << "min=" << e.min() << endl;
}
