sort in c++; code example

Example 1: c++ sort

int arr[]= {2,3,5,6,1,2,3,6,10,100,200,0,-10};
    int n = sizeof(arr)/sizeof(int);  
    sort(arr,arr+n);

    for(int i: arr)
    {
        cout << i << " ";
    }

Example 2: stl sort in c++

sort(arr, arr+n, greater<int>()); // sorts in descending order
