模板类实现顺序栈 

#include <iostream>

using namespace std;
template <typename T>
class Seqlite{

        T data[30];
        int len=0;
public:

    void head_inst(T date);
    void head_dele();
    void show();
};
template <typename T>                     //头插函数
void Seqlite<T>::head_inst(T date){
   if(len<30){
        for(int i=len;i>0;i--){
            data[i]=data[i-1];
        }
        data[0]=date;
        len++;
   }else
       cout << "不合理，重写！" << endl;
}
template <typename T>                     //头删函数

template <typename T>
void Seqlite<T>::show(){                 //展示函数

 模板类实现链队列

#include <iostream>
//实现链队列
using namespace std;
template <typename T>
class Link{
    T data;
    Link* next=nullptr;
public:
    void head_inst(T date);
    void tail_dele();
    void show();
};
template <typename T>
void Link<T>::head_inst(T date){
    Link* ack=new Link;
    ack->data=date;
    if(this->next!=nullptr){
        ack->next=next;
    }
    next=ack;
}
template <typename T>
void Link<T>::tail_dele(){
    if(next==nullptr){
        cout << "啥也妹有" << endl;
        return;
    }
    Link* p=this;
    while(p->next->next){
        p=p->next;
    }
    cout << (p->next)->data << "已出队" << endl;
    Link* q=p->next;
    p->next=nullptr;
    delete(q);

}
template <typename T>
void Link<T>::show(){
    if(next==nullptr){
        cout << "啥也没有啊" << endl;
        return ;
    }
    Link* p=this;
    while(p->next!=nullptr){
        cout << p->next->data << '\t' ;
        p=p->next;
    }
    cout << endl;
}
int main()
{
    Link<int> H;
    H.head_inst(19);
    H.head_inst(89);
    H.head_inst(119);
    H.show();
    H.tail_dele();
    H.show();
    H.tail_dele();
    return 0;
