How to sort an Array using STL in C++?
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}
Approach: Sorting can be done with the help of sort() function provided in STL.
Syntax:
sort(arr, arr + n);
#include <bits/stdc++.h>
using namespace std;
int main()
{
int arr[] = { 1, 45, 54, 71, 76, 12 };
int n = sizeof (arr) / sizeof (arr[0]);
cout << "Array: " ;
for ( int i = 0; i < n; i++)
cout << arr[i] << " " ;
cout << endl;
sort(arr, arr + n);
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
