max element in array c++ stl

*max_element (first_index, last_index);
ex:- for an array arr of size n
*max_element(arr, arr + n);

c++ max of array

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

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;
}

max element of an array stl c++

    vector<int>arr {1, 34 , 50, 4, 400};
    int maximumElement = *max_element(arr.begin(), arr.end());
    int minimumElement = *min_element(arr.begin(), arr.end());

Max element in an array with the index in c++

int main(int argc, char** argv) {
  int A[4] = {0, 2, 3, 1};
  const int N = sizeof(A) / sizeof(int);

  cout << "Index of max element: "
       << distance(A, max_element(A, A + N))
       << endl;

  return 0;
