本文介绍了一个使用C++模板类实现的最大值和最小值比较器。该模板类可以用于不同类型的数值，如整数、浮点数和字符等，通过实例化不同的对象来展示如何获取两个数之间的最大值和最小值。

#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;
	numtype 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> cmp1(3,7);
	cout<<cmp1.max()<<" is the Maximum of two integer numbers."<<endl;
	cout<<cmp1.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;
	
	return 0;
}
