what is the short cut way to find the max and min element in an array in c++

cout<< *max_element(arr.begin(), arr.end());

cout<< *min_element(arr.begin(), arr.end());

find max element in array c++

#include <iostream>
using namespace std;
//How to find max element in C++
int main() {
	int n;
	cout <<"How many element yo will enter?"<<endl;
	cin >> n;
	int arr[n];
	for(int i=0;i<n;i++){
		cout << "Your "<< i+1 <<" number : ";
		cin >> arr[i];
	}
	for(int i=0;i<n;i++){
		if(arr[0]<arr[i]){
			arr[0]=arr[i];
		}
	}
	cout << "The max element is :"<<arr[0];
	
	return 0;
}

array max and minimum element c++

class findMaxMinFromArray

minimum or maximum in array c++

#include <iostream>
#include <climits>
#include <algorithm>
using namespace std;
 
int main()
{
    int arr[] = { 4, 2, 1, 6, -8, 5 };
 
    int min = INT_MAX, max = INT_MIN;
    for (int i: arr)
    {
        if (i < min) {
            min = i;
        }
 
        if (i > max) {
            max = i;
        }
    }
 
    std::cout << "The min element is " << min << std::endl;
    std::cout << "The max element is " << max << std::endl;
 
    return 0;
}

minimum or maximum in array c++

#include <iostream>
#include <time.h>

using namespace std;

int main()

    double array[6];
    double min=array[6];
    double max=array[0];

        cout<<"Element "<<i<<": ";
        cout<<array[i]<<endl;
      if(array[i]>max){
          max=array[i];

          indexOfMin=i;
      }
    }
    cout<<"The minimum value is "<<min<<endl;
    cout<<"The index of the minimum value is "<<indexOfMin<<endl;
    cout<<"The maximum value is "<<max<<endl;
