模板类的使用

使用模板类，可以使用各种的数据成员对函数进行操作，
模板类的形式
tempalte

#include<iostream>
using namespace std;
template<class T>
class compare
{
public:
    compare(T a, T b);
    T min();
    T max();
private:
    T num1;
    T num2;
};
template<class T>
compare<T>::compare(T a, T b)
{
    num1 = a;
    num2 = b;
}
template<class T>
T compare<T>::min()
{
    if (num1 > num2)
        return num2;
    else
        return num1;

}
template<class T>
T compare<T>::max()
{
    if (num1 > num2)
        return num1;
    else
        return num2;
}

int main()
{
    compare<int> com1(20, 10);
    cout << "the min of the number" << com1.min() << endl;
    cout << "the max of the number" << com1.max() << endl;
    compare < double> com2(15.6, 13.8);
    cout << "the min of the min number" << com2.min() << endl;
    cout << "the max of the number" << com2.max() << endl;
    system("pause");
    return 0;
}
