emplace push 能用的 emplace 也能用, 但是emplace 可以直接传入构造对象所需要的元素, 然后自己调用构造函数, 然后入栈. 如果需要构造对象,使用 emplace 比 push 更为节省内存(push 需要自己构造 + 拷贝爱) swap 交换两个 Stack 中的内容, 比如满足 T/Container 一致版权声明:本文为Hoooo_23

void push( const value_type& value ); (1) void push( value_type&& value ); (2) (since C++11) Pushes the given element value to the top of the stack. 1) Equivalent to: c.push_back(value).2) Equivalent to: c.push_back(std::move(value))....

与Container::emplace_back 的复杂度相同。 示例运行此代码 #include <iostream> #include <stack> struct S { int id; S(int i, double d, std::string s) : id{i} { std::cout << "S::S(" << i << ", " << d << ", \"" << s << "\");\n"; } }; int main() { std:...
void pop(); 从stack 移除顶元素。等效地调用 c.pop_back() 。 参数 (无) 返回值 (无) 复杂度 等于Container::pop_back 的复杂度。 参阅 emplace(C++11) 于顶原位构造元素(公开成员函数) push 向栈顶插入元素(公开成员函数) top 访问栈顶元素(公开成员函数) ...
