采用了三種實現方法：

1、自己定義數組（Stack 堆棧數組大小不能動態增加）

2、使用STL的vector（Vector_Stack 堆棧數組可動態變化）

3、使用STL的list（List_Stack 堆棧數組可動態變化）

以下是stack.h的頭文件，所有接口函數都寫為內聯，因此沒有實現文件。

檢驗代碼：

// 模板（棧）.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include "stack.h"

#include <vector>
#include <iostream>

using namespace std;

int main(int argc, char* argv[])
{
/************************************************************************/
/* Stack */
/************************************************************************/
cout<<"********** Stack **********"<<endl;

int i,nSize;
int data;
const int size = 3;

cout<<"set stack size=3"<<endl;

for (i=0;i<3;i )
{

intStack.Push(data);
cout<<"push "<<data<<endl;
}
cout<<"size="<<intStack.Size()<<endl;

for (i=0;i<size 1;i )
{

{
cout<<"pop data:"<<data<<endl;
}
}
cout<<"size="<<intStack.Size()<<endl<<endl;

/************************************************************************/

cout<<"push "<<data<<endl;
}
nSize = vIntStack.Size();

for (i=0;i<nSize 1;i )
{
vIntStack.Pop(&data);
cout<<"pop data:"<<data<<endl;
}
nSize = vIntStack.Size();
cout<<"size="<<nSize<<endl;

運行結果為：
