c++ get max array

int main() // taken from Programiz 
{ //
    int i, n;
    float arr[100];

    cout << "Enter total number of elements(1 to 100): ";
    cin >> n;
    cout << endl;

    // Store number entered by the user
    for(i = 0; i < n; ++i)
    {
       cout << "Enter Number " << i + 1 << " : ";
       cin >> arr[i];
    }

    // Loop to store largest number to arr[0]
    for(i = 1;i < n; ++i)
    {
       // Change < to > if you want to find the smallest element
       if(arr[0] < arr[i])
           arr[0] = arr[i];
    }
    cout << "Largest element = " << arr[0];

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
}
