std::priority_queue<T,Container,Compare>::emplace std::priority_queue<T,Container,Compare>::pop std::priority_queue<T,Container,Compare>::swap std::priority_queue 的推导指引 std::swap(std::priority_queue) std::uses
std::priority_queue<T, Container, Compare>& rhs ) noexcept(/* 见下文 */); (C++17 起) 为std::priority_queue 特化了 std::swap 算法。交换 lhs 与rhs 的内容。调用 lhs.swap(rhs)。 此重载只有在 std::is_swappable_v<Container> 与std::is_swappable_v<Compare> 均为true时才会参与重载决议。
std::priority_queue 是在 C++98 标准中引入的。C++98 是第一个官方批准的 C++ 标准,它在很大程度上奠定了 C++ 语言的基础,并引入了 STL(Standard Template Library),STL 包括了一系列标准的模板类和函数,用…
