c++之类模板对象作函数参数

#include<iostream>
using namespace std;

template<class T1,class T2>
class Person {
public:
    T1 name;
    T2 age;
    Person(T1 name,T2 age) {
        this->name = name;
        this->age = age;
    }
    void show() {
        cout << "姓名是：" << this->name << " " << 年龄是：this->age << endl;
    }
};

//1.指定传入类型
void printPerson1(Person<string,1)">int>& p) {
    p.show();
}
2.参数模板化
template<void printPerson2(Person<T1,T2> &p) {
    cout << T1的参数类型是：" << typeid(T1).name() << endl;
    cout << T2的参数类型是：" << typeid(T2).name() << endl;
    p.show();
}
3.整个类模板化
template<class T>
void printPerson3(T &T的参数类型是：" << typeid(T).name() << endl;
    p.show();
}

 test() {
    Person<int> p(tom",12);
    printPerson1(p);
    printPerson2(p);
    printPerson3(p);
}

int main() {
    test();
    system(pause");
    return 0;
}
