max till i array problem c++ code example

Example 1: max array c++

auto Max1 = *max_element(ForwardIt first, ForwardIt last);
auto Max2 = *max_element(ForwardIt first, ForwardIt last, Compare comp);

//Example:
#include <bits/stdc++.h>
using namespace std;
main() {
    vector<int> v{ 3, 1, -14, 1, 5, 9 }; 
    int result;
    
    result = *max_element(v.begin(), v.end());
    cout << "max element is: " << result << '\n'; // 9
 
    result = *max_element(v.begin(), v.end(), [](int a, int b) { return abs(a)<abs(b); });
    cout << "max element (absolute) is: " << result << '\n'; //-14
}

Example 2: find max value in array c++

cout << " max element is: " << *max_element(array , array + n) << endl;
