c++ stl栈stack介绍
C++ Stack（堆栈） 是一个容器类的改编，为程序员提供了堆栈的全部功能，——也就是说实现了一个先进后出（FILO）的数据结构。
c++ stl栈stack的头文件为:
#include <stack>
c++ stl栈stack的成员函数介绍
操作 比较和分配堆栈
empty() 堆栈为空则返回真
pop() 移除栈顶元素
push() 在栈顶增加元素
size() 返回栈中元素数目
top() 返回栈顶元素
c++ stl栈stack用法代码举例1
| #include "stdafx.h"
#include <stack>
#include <vector>
#include <deque>
#include <iostream>
using namespace std;
int _tmain(int argc, _TCHAR* argv[])
{
deque<int> mydeque(2,100);
vector<int> myvector(2,200);
stack<int> first;
stack<int> second(mydeque);
stack<int,vector<int> > third;
stack<int,vector<int> > fourth(myvector);
cout << "size of first: " << (int) first.size() << endl;
cout << "size of second: " << (int) second.size() << endl;
cout << "size of third: " << (int) third.size() << endl;
cout << "size of fourth: " << (int) fourth.size() << endl;
return 0;
}

c++ stl栈stack用法代码举例2
| // stack::empty
#include <iostream>
#include <stack>
using namespace std;
int main ()
{
stack<int> mystack;
int sum (0);
for (int i=1;i<=10;i++) mystack.push(i);
while (!mystack.empty())
{
sum += mystack.top();
mystack.pop();
}
cout << "total: " << sum << endl;
return 0;
}

c++ stl栈stack用法代码举例3
| // stack::push/pop
#include <iostream>
#include <stack>
using namespace std;
int main ()
{
stack<int> mystack;
for (int i=0; i<5; ++i) mystack.push(i);
cout << "Popping out elements...";
while (!mystack.empty())
{
cout << " " << mystack.top();
mystack.pop();
}
cout << endl;
return 0;
}
