# include<iostream>
# include<string>
using namespace std;
//一共有三种传入方式
template<class T1, class T2>
class Person
{
public:
	Person(T1 name, T2 age)
	{
		this->m_Name = name;
		this->m_Age = age;
	}
	void showPerson()
	{
		cout << "姓名：" << this->m_Name << " 年龄：" << this->m_Age << endl;
	}
	T1 m_Name;
	T2 m_Age;

};
//1、指定传入的类型 --直接显示传入的数据类型

void printPerson1(Person<string, int>&p)
{
	p.showPerson();
}
void test01()
{
	Person<string,int>p("孙悟空",999);
	printPerson1(p);

}
//2、参数模板化
template<class T1,class T2>
void printPerson2(Person<T1, T2>& p)
{
	p.showPerson()
