How to sort an Array using STL in C++?
• Last Updated : 19 Mar, 2019

Given an array arr[], sort this array using STL in C++.

Example:

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

Input: arr[] = {1, 7, 5, 4, 6, 12}
Output: {1, 4, 5, 6, 7, 12}
```

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

Approach: Sorting can be done with the help of sort() function provided in STL.

Syntax:

```sort(arr, arr + n);
```
 `// C++ program to sort Array``// using sort() in STL`` ` `#include ``using` `namespace` `std;`` ` `int` `main()``{`` ` `    ``// Get the array``    ``int` `arr[] = { 1, 45, 54, 71, 76, 12 };`` ` `    ``// Find the size of the array``    ``int` `n = ``sizeof``(arr) / ``sizeof``(arr[0]);`` ` `    ``// Print the array``    ``cout << ``"Array: "``;``    ``for` `(``int` `i = 0; i < n; i++)``        ``cout << arr[i] << ``" "``;``    ``cout << endl;`` ` `    ``// Sort the array``    ``sort(arr, arr + n);`` ` `    ``// Print the sorted array``    ``cout << ``"Sorted Array: "``;``    ``for` `(``int` `i = 0; i < n; i++)``        ``cout << arr[i] << ``" "``;``    ``cout << endl;`` ` `    ``return` `0;``}`
Output:
```Array: 1 45 54 71 76 12
Sorted Array: 1 12 45 54 71 76
