C++ STL stack::push() function with example: In this article, we are going to see how to push an element into a stack using C++ STL? Submitted by Radib Kar, on February 03, 2019 C++ STL - stack::push() FunctionThe push() function is used to insert a new element at the top of...

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...
colors.push("Orange"); cout<<"Stack: ";// print elements of stackwhile(!colors.empty()) {cout<< colors.top() <<", "; colors.pop(); }return0; } Run Code Output Stack: Orange, Red, In the above example, we have created a stack of strings calledcolors. Then, we have used the...
0 - Exit. 1 - Push Item. 2 - Pop Item. 3 - Display Items (Print STACK). Enter your choice: 1 Enter item to insert: 10 10 inserted. 0 - Exit. 1 - Push Item. 2 - Pop Item. 3 - Display Items (Print STACK). Enter your choice: 1 Enter item to insert: 20 20 inserted. ...
stk.push(1); // stk : 1 stk.push(5); // stk : 5 1 还有一种方法是用emplace()函数进行入栈,两者差别可以暂时忽略。 代码语言:c++ AI代码解释 stk.emplace(7); // stk : 7 5 1 出栈 stk.pop()将stk的栈顶元素弹出栈,复杂度O(1)。
因为原子操作就是Push()函数中的compare_exchange_weak(),所以需要获取两个线程间的先行(happens-before)关系。compare_exchange_weak()必须是std::memory_order_release或更严格的内存序。不过,compare_exchange_weak()调用失败时,什么都不会改变,并且可以持续循环下去,所以使用std::memory_order_relaxed就足够了。
