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。

主函数中如下创建

Compare<int> cmp1(3,4);

Compare<float> cmp2(45.78,93.6);

Compare<char> cmp3('a','A');

那么输出为：

4 is the Maximum of two inteder numbers.
3 is the Minimum of two inteder numbers.

93.6 is the Maximum of two float numbers.
45.78 is the Minimum of two float numbers.

a is the Maximum of two characters.
A is the Minimum of two characters.
