C++ 70 之 类模版中的成员函数，在类外实现

#include <iostream>
#include <string>
using namespace std;template<class T1, class T2>
class Students10{
public:T1 m_name;T2 m_age;Students10(T1 name, T2 age);  // 类内声明   类外实现// {//     this->m_name = name;//     this->m_age = age;// }void show();// {//     cout << "姓名: " << this->m_name << "年龄: " << this->m_age << endl;// }
};// 无论函数中是否用到T1、T2 都要写在类名后面的尖括号中
template<class T1, class T2>
Students10<T1,T2>::Students10(T1 name, T2 age){this->m_name = name;this->m_age = age;
}template<class T1, class T2>
void Students10<T1,T2>::show(){cout << "姓名: " << this->m_name << "年龄: " << this->m_age << endl;
}int main()
{Students10<string, int> stu("张阿三",18);stu.show();return 0;
}
