Pointer function:

[Chubby]

I am trying to make a information to pointer function but the problem is how/what number am i putting in for *a...

and can i get that information back to main? and is that right way to split the array in to ? because i have will 200 random number and I need to find the smallest and second smallest element in array.

  two_smallest (print, size3,size3,size3,size3);
}
void two_smallest (int find_array[] , int size3, int *a, int *a2, int *b,int *b2)
{
    for (int index = 0; index <= 100; index ++)
    {
        if (find_array[index] < find_array [0])
        {
            find_array[0] = find_array [index];
            *a = find_array[0];

        }
    }
    cout <<"The first lowest number in this call is " << *a << endl;
    
    for (int index_2=101 ; index_2 < 200; index_2 ++)
    {
        if (find_array [index_2] < find_array [0])
        {
            find_array [0] = find_array [index_2];
            *b = find_array[0];
        }
    }
    cout <<"The second lowest number is " << *a << endl;
    
    
   

}

size3= 200
