How to find the minimum and maximum element of an Array using STL in C++?
  • Difficulty Level : Easy
  • Last Updated : 26 Oct, 2020

Given an array arr[], find the minimum and maximum element of this array using STL in C++.
Example: 

Input: arr[] = {1, 45, 54, 71, 76, 12}
Output: min = 1, max = 76

Input: arr[] = {10, 7, 5, 4, 6, 12}
Output: min = 1, max = 76

Approach:  

  • Min or Minimum element can be found with the help of *min_element() function provided in STL.
  • Max or Maximum element can be found with the help of *max_element() function provided in STL.

Syntax:  

*min_element (first, last);

*max_element (first, last);

The range used is [first,last), which contains all the elements between first and last, including the element pointed by first but not the element pointed by last.

Below is the implementation of the above approach: 

CPP




// C++ program to find the min and max element
// of Array using sort() in STL
 
#include <bits/stdc++.h>
using namespace std;
 
int main()
{
    // Get the array
    int arr[] = { 1, 45, 54, 71, 76, 12 };
 
    // Compute the sizes
    int n = sizeof(arr) / sizeof(arr[0]);
 
    // Print the array
    cout << "Array: ";
    for (int i = 0; i < n; i++)
        cout << arr[i] << " ";
 
    // Find the minimum element
    cout << "\nMin Element = "
         << *min_element(arr, arr + n);
 
    // Find the maximum element
    cout << "\nMax Element = "
         << *max_element(arr, arr + n);
    return 0;
}
Output: 
Array: 1 45 54 71 76 12 
Min Element = 1
Max Element = 76
