Span of an Array

#include <iostream>
using namespace std;

int main()
{
	// Creating the array and nth value
	int n;
	cout << "Enter nth number of values: ";
	cin >> n;
	cout << "Enter the values:" << endl;

	// Entering values into the array
	int* arr = new int[n];
	for (int i = 0; i < n; i++){
		cin >> arr[i];
	}

	// Maximum and Minimum values
	int min = arr[0];
	int max = arr[0];

	// For-loop calculates maximum and minimum values of the array
	for (int i = 1; i < n; i++){
		if (arr[i] > max){
			max = arr[i];
		}

	}

	// Display maximum and minimum values
	cout << "\nMax: "<< max << endl;

	// Display the span of the array
	int span = max - min;
