{
    for (int i=0; i<n ;i++)
    {
        int random = i + (rand() % (52 -i));     // randomising the values

        swap(card[i], card[random]);             // swapping previous value with random value
    }
}
int main()
{
    int array[] = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52};
    int size = sizeof(array) / sizeof(array[0]);   // array size declaration
    shuffle_deck(array, size);                     // calling shuffle function
    for (int i=1; i<=size; i++)
   {
        cout << array[i] << " ";                   // printing random or shuffled values
    }
    cout << endl;

    return 0;
