能够掌握类模板中的成员函数的类外实现：

#include <iostream>
#include <Windows.h>
#include <string>using namespace std;template<typename T1, typename T2>
class Person
{
public:T1 m_Name;T2 m_Age;Person(T1 name, T2 age);void showPerson();
};// 构造函数类外实现
template<typename T1, typename T2>
Person<T1, T2>::Person(T1 name, T2 age)
{m_Name = name;m_Age = age;
}// 成员函数的类外实现
template<typename T1, typename T2>
void Person<T1, T2>::showPerson()
{cout << "姓名：" << m_Name << " 年龄：" << m_Age << endl;
}void test()
{Person<string, int> p("张三", 18);p.showPerson();
}int main(void)
{test();system("pause");return 0;
}
