例9.14 声明一个类模板，利用它分别实现两个整数、浮点数和字符的比较，求出大数和小数。
#include <iostream>
using namespace std;
template<class numtype>                //定义类模板
class Compare
{public:
Compare(numtype a,numtype b)
{x=a;y=b;}
numtype max( )
{return (x>y)?x:y;}
numtype min( )
{return (x<y)?x:y;}
private:
numtype x,y;
};

int main( )
{Compare<int> cmp1(3,7);            //定义对象cmp1，用于两个整数的比较
cout<<cmp1.max( )<<″ is the Maximum of two integer numbers.″<<endl;
cout<<cmp1.min( )<<″ is the Minimum of two integer numbers.″<<endl<<endl;
Compare<float> cmp2(45.78,93.6);   //定义对象cmp2，用于两个浮点数的比较
cout<<cmp2.max( )<<″ is the Maximum of two float numbers.″<<endl;
cout<<cmp2.min( )<<″ is the Minimum of two float numbers.″<<endl<<endl;
Compare<char> cmp3(′a′,′A′);       //定义对象cmp3，用于两个字符的比较
cout<<cmp3.max( )<<″ is the Maximum of two characters.″<<endl;
cout<<cmp3.min( )<<″ is the Minimum of two characters.″<<endl;
return 0;
}
