ForwardIt max_element(ExecutionPolicy&&policy, ForwardIt first, ForwardIt last, Compare comp); (4)(C++17 起) 寻找范围[first,last)中的最大元素。 1)用operator<(C++20 前)std::less{}(C++20 起)比较元素。 3)用比较函数comp比较元素。

vector<int> numbers = {1, 7, 3, 5, 9, 2}; auto it = max_element(numbers.begin(), numbers.end()); if (it != numbers.end()) { cout << *it << " is the highest value"; } else { cout << "The vector is empty"; } ...
This function returns an iterator to the max element in the container: Copy #include<iostream>#include<vector>#include<algorithm>intmain()/*fromwww.java2s.com*/{ std::vector<int> v = { 1, 2, 3, 4, 5 };autoit = std::max_element(std::begin(v), std::end(v)); ...
以下是详细步骤和代码示例,用于演示如何使用std::max_element函数求数组的最大值: 定义一个数组并初始化: 首先,我们需要定义一个数组并对其进行初始化。数组可以是任意类型,例如整数数组、浮点数数组等。 cpp int arr[] = {10, 5, 20, 15, 30}; 使用std::max_element函数找出数组中的最大元素: std::...
The function "del_max(num)" return 0 directly , because before you call this function. All elements are deleted. There are no elements, so "if" will not execute at all. First of all, int pop(int& n) just deletes first element ,that's true,but you put this function to conditional...
