我正在尝试使用链表实现堆栈类这里是我的stack.h

// File: Stack.h

#ifndef STACK_H
#define STACK_H
class Stack
{

private:
    struct linklst{
        int num;
        int* next;
    };

    linklst* top;

public:
    Stack();
    ~Stack();

    void push(int i);
    int pop();
    bool isempty();

};

#endif

和我的堆栈.cpp

// Stack.cpp

#include"Stack.h"
using namespace std;

 Stack::Stack(){
     top = new linklst();
     top->num = -1;
     top->next = nullptr;

 };

 Stack::~Stack() {

     linklst * r = new linklst();
     while (true)
     {

         r = top;
         top = top->next;
         delete r;


     }

     delete top;


 };

 void Stack::push(int i){

     linklst * …
