It's a example of doing sort by using sort function in C++. We can use this function to sort

normal any numbers very easily .

#include

using namespace std;

int main()

{

    int arr[] = {1, 5, 8, 9, 6, 7, 3, 4, 2, 0};

    int n = sizeof(arr)/sizeof(arr[0]);

    sort(arr, arr+n);

    cout << "\nArray after sorting using "

         "default sort is : \n";

    for (int i = 0; i < n; ++i)

        cout << arr[i] << " ";

    return 0;

}
