此算法不仅在效率上与std::make_pair(std::min_element(),std::max_element())不同,而且此算法寻找最后 的最大元素,而std::max_element寻找首个 最大元素。 示例 参阅 min_element 返回范围中最小元 (函数模板) max_element 返回范围中最大元 ...
max (4) template<classT,classCompare>T max(std::initializer_list<T>ilist, Compare comp){return*std::max_element(ilist.begin(), ilist.end(), comp);} 注解 如果参数之一是临时量,而该参数被返回,那么以引用捕获std::max的结果会产生一个悬垂引用: ...
http://en.cppreference.com/w/cpp/algorithm/min_element 主要有两种用法 template< class ForwardIt > ForwardIt min_element( ForwardIt first, ForwardIt last ); 和 template< class ForwardIt, class Compare > ForwardIt min_element( ForwardIt first, ForwardIt last, Compare comp );。其中第一种采...
