c++重要指令 -- std::stake 的使用方法

std::stake 的使用方法

1. stake 特性: last-in first-out

2.重要的Member functions :

empty: Test whether container is empty

size: Return size

top: Access next element

push: Insert element

pop: Remove top element

emplace(c++11): Construct and insert element

swap(c++11): Swap contents

3. 使用Example:

#include <iostream>       // std::cout
#include <stack>          // std::stack

int main ()
{
  std::stack<int> myints;//宣告
  std::cout << "0. size: " << myints.size() << '\n';     //Return size

  for (int i=0; i<5; i++) myints.push(i);                // Insert element
  std::cout << "1. size: " << myints.size() << '\n'; 

  myints.pop();                                          //Remove top element
  std::cout << "2. size: " << myints.size() << '\n';

  return 0;
}

ps. The standard container classes vector, deque and list fulfill these requirements. By default, if no container class is specified for a particular stack class instantiation, the standard container deque is used.
