C++类模板的使用

#include<iostream>
#include<string>
#include<typeinfo>
using namespace std;
template <class Name,class Hobby,class Age>  //类模板做函数的参数 
class Dog{
private:
    Name m_name;
    Hobby m_hobby;
    Age m_age;

public:
    Dog(Name name,Hobby hobby,Age age){
        this->m_name=name;
        this->m_hobby=hobby;
        this->m_age=age;
    }
    void display(){
        cout<<"m_name:"<<m_name<<" m_hobby:"<<m_hobby<<" m_age:"<<m_age<<endl;
    }
};

void dis1(){
    Dog<string,string,int> dog1("小灰","吃",2);
    dog1.display();
}

// 参数模板化
template<class Name,class Hobby,class Age>
void dis2(Dog<Name,Hobby,Age> dog){  // 传递类
    cout << typeid(Name).name() << endl;
     cout << typeid(Hobby).name() << endl;
     cout << typeid(Age).name() << endl;
    dog.display();
}

// 整体类型化
template<class T>
void dis3(T &dog){  // 传递类
    cout << typeid(T).name() << endl;
    dog.display();
}

// 指定传入类型
void dis4(Dog<string,string,int> dog) {  // 传递数据类型
    dog.display();
}

int main(){
    Dog<string,string,int> dog2("小黑","睡",1);
    dis1();
    dis2(dog2);
    dis3(dog2);
    dis4(dog2);
    return 0;
}

注意：该程序在乌班图下会出现错位如图所示：

解决方法是：在生成的test文件下打开终端执行 ./test | c++filt -t 或在生成的a.out文件夹下执行./a.out | c++filt -t结果如下：

c++ filt使用方法：在终端执行：man C++FILT 命令 会出现：
