与Container::emplace_back 的复杂度相同。 示例运行此代码 #include <iostream> #include <queue> 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:...
The value or reference, if any, returned by the above call toContainer::emplace_back. (since C++17) Complexity Identical to the complexity ofContainer::emplace_back. Example Run this code #include <iostream>#include <queue>structS{intid;S(inti,doubled,std::strings):id{i}{std::cout<<"S...

Pushes a new element to the priority queue. The element is constructed in-place, i.e. no copy or move operations are performed. The constructor of the element is called with exactly the same arguments as supplied to the function. Effectively calls c.emplace_back(std::forward<Args>(args...
对数次比较加上 Container::emplace_back 的复杂度。 示例运行此代码 #include <iostream> #include <queue> struct S { int id; S(int i, double d, std::string s) : id{i} { std::cout << "S::S(" << i << ", " << d << ", \"" << s << "\");\n"; } friend bool ...
