以下是一个示例代码,演示如何使用max_element的transform_reduce来计算给定范围内的最大值并求和: 代码语言:cpp 复制 #include<iostream>#include<algorithm>#include<numeric>#include<vector>intmain(){std::vector<int>numbers={1,2,3,4,5};// 使用max_element找到最大元素的迭代器automaxElement=std::max_el...
ForwardIt max_element(ExecutionPolicy&&policy, ForwardIt first, ForwardIt last, Compare comp); (4)(since C++17) Finds the greatest element in the range[first,last). 1)Elements are compared usingoperator<(until C++20)std::less{}(since C++20). ...
std::vector<int> v = { 1, 2, 3, 4, 5 };autoit = std::max_element(std::begin(v), std::end(v)); std::cout <<"The max element in the vector is: "<< *it; }
