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
// 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;
}
运行结果
total:55

#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; }
运行结果
ize of first:0
size of second:2
size of third:0
size of fourth:2
