#### 习题 9.12 将例9.14改写为在类模板外定义各成员函数。 ####

代码块：

#include <iostream>
    using namespace std;
    template <class numtype>
    class Compare
    {
    public:
        Compare(numtype a, numtype b){
            x=a;
            y=b;
        }
        numtype max();
        numtype min();
    private:
        numtype x, y;
    };
    template <class numtype>
    numtype Compare <numtype>::max()
    {
        return x>y ? x : y;
    }
    template <class numtype>
    numtype Compare <numtype>::min()
    {
        return x<y ? x : y;
    }
    int main()
    {
        Compare <int> cmpl(3, 7);
        cout<<cmpl.max()<<" is the Maximum of two integer numbers."<<endl;
        cout<<cmpl.min()<<" is the Minimum of two integer numbers."<<endl;
        Compare <float> cmp2(45.78, 93.6);
        cout<<cmp2.max()<<" is the Maximum of two float numbers."<<endl;
        cout<<cmp2.min()<<" is the Minimum of two float numbers."<<endl;
        Compare <char> cmp3('a', 'A');
        cout<<cmp3.max()<<" is the Maximum of two characters."<<endl;
        cout<<cmp3.min()<<" is the Minimum of two characters."<<endl;
        system("pause");
        return 0;
    }
