How to make a list of binary numbers

I want to have a function to make a list of binary random numbers.. I don't know which method is appropriate for this purpose. I can make it with an array , a while command, linked list or a std ..

I want to return the whole list from the function. In array i think i can't do that. For example the following function only return the first elements.

long int  SourceNode::database(long int chunk_var[])
{
    srand ( time(0) );
    for(int j = 0; j<50 ;j++)
    {
        int myrand = rand() % 2 ;
        myrand = myrand & 0x3ff;
        chunk_var[j]= myrand;
    }
    return *chunk_var;
}

i want something to return the whole list, because i want to invoke that function( the whole list) in another function . is there any alternative solution instead of making an array?
