stack是一种先进后出(First In Last Out,FILO)的数据结构。它只有一个出口, 形式如下图所示 特点: stack允许新增元素、移除元素、取得最顶端元素。但除了最顶端外,没有任何其他方法可以存取stack的其他元素。换言之stack不允许有遍历行为 将元素推入stack的动作称为push,将元素推出stack的动作称为pop 底层实现: SG...
This article will demonstrate STL functions for calculating the exponential in C++.Use the std::exp Function to Calculate Powers of Euler’s NumberThe std::exp function is part of the <cmath> header along with many common mathematical functions. The former calculates Euler’s number raised to ...

本文实现STL在stack大部分功能,同时加入了许多功能。 请注意以下几点: 1.Stack它是一个适配器,在底部vector、list、deque等实现 2.Stack不含有迭代器 在本例中,我加入了几项功能,包含不同类型stack之间的复制和赋值功能,能够实现诸如Stack<int, vector<int> >和Stack<double, list<double> >之间的复制和赋值,...
// StackSize.cpp // compile with: /EHsc // Illustrates how to use the size function to determine // the number of elements on the stack. // // Functions: // // size : returns the number of elements in the stack. /// #pragma warning(disable:4786) #include <stack> #include <str...

The core interface of stacks is provided by the member functionspush(), top(),andpop(): push()inserts an element into the stack. top()returns the next element in the stack. pop()removes an element from the stack. stack<ElementType> ccreate a empty stack. ...
stack: 执行 LIFO (Last in First out)操作。默认为底层为 deque 来实现。 Member functions empty: size: top: push: pop: emplace(c++11): swap(c++11): ===STL源码剖析部分补充=== 1,stack 是适配器而不是容器,原因是:由于 stack 系以底部...
It then proceeds to find the maximum and minimum elements within this vector using the std::max_element and std::min_element functions provided by the STL. To store and return these two values, the function creates a std::pair<int, int> named ret, where the first value (.first) is ...
