5、 顺序栈

 

SeqStack.h

 

template<typename Type> class SeqStack{

public:

   SeqStack(int sz):m_ntop(-1),m_nMaxSize(sz){

     m_pelements=new Type[sz];

     if(m_pelements==NULL){

   Type Pop();                 //pop data

   Type GetTop() const;        //get data

    void Print();               //print the stack

   void MakeEmpty(){           //make the stack empty

     m_ntop=-1;

   }

   bool IsEmpty() const{

   for(int i=0;i<=m_ntop;i++){

     cout<<"--->"<<m_pelements[i];

   }

   cout<<"--->top"<<endl<<endl<<endl;

Test.cpp

 

#include<iostream>

using namespace std;

 

#include "SeqStack.h"

 

int main(){

   SeqStack<int> stack(10);

   int init[10]={1,2,6,9,0,3,8,7,5,4};

   stack.Print();

   stack.Pop();

   return 0;

}

 

6、 链式栈

 

StackNode.h

 

template<typename Type> class LinkStack;

 

template<typename Type> class StackNode{

private:

   friend class LinkStack<Type>;

   StackNode(Type dt,StackNode<Type> *next=NULL):m_data(dt),m_pnext(next){}

 

private:

   Type m_data;

   StackNode<Type> *m_pnext;

};

 

LinkStack.h

 

#include "StackNode.h"

 

template<typename Type> class LinkStack{

public:

   LinkStack():m_ptop(NULL){}

   ~LinkStack(){

     MakeEmpty();

   }

 

public:

   void MakeEmpty();           //make the stack empty

   void Push(const Type item); //push the data

   Type Pop();                 //pop the data

   Type GetTop() const;        //get the data

    void Print();               //print the stack

       

   bool IsEmpty() const{

     return m_ptop==NULL;

   }

  

private:

   StackNode<Type> *m_ptop;

};
