# How to find the minimum and maximum element of an Array using STL in C++?

• Difficulty Level : Easy
• Last Updated : 07 Jul, 2022

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 = 4, max = 12```

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);```

To use *min_element() and *max_element() you must include “algorithm” as a header file.

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 ``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);` `    ``// 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);``    ``// Storing the pointer in an address``    ``int` `&min = *min_element(arr,arr+n );``    ``int` `&max = *max_element(arr,arr+n );``    ``cout<<``"\nFinding the Element using address variable"``;``    ``cout<<``"\nMin Element = "``<

Output

```Array: 1 45 54 71 76 12
Min Element = 1
Max Element = 76
Finding the Element using address variable
Min Element = 1
Max Element = 76```

Time Complexity: O(N)
Auxiliary Space: O(1)
