当vector数组为空时,std::min_element会返回一个迭代器,该迭代器等于容器的end()迭代器。在逻辑上,这个返回值可以被视为表示“没有找到任何元素”,因为确实没有元素可供比较。 代码示例 为了更清楚地说明这一点,我们可以编写一个简单的代码示例: cpp #include <iostream> #include <vector> #in...
min_element ( s1.begin ( ) , s1.end ( ) ); cout << "The smallest element in s1 is: " << *s1_R1_Iter << endl; cout << endl; // Searching a vector with elements of type int for the maximum // element under default less than & mod_lesser binary predicates vector <int> v...

This post will discuss how to find the min or max value in a vector in C++. 1. Using std::max_element The std::min_element and std::max_element return an iterator to the minimum and the maximum value in the specified range, respectively. The following code example shows invocation for...
