This is defining an array of 4 integers. The elements of the array can be 
accessed as d[0],d[1],d[2],d[3] (in general, array x[n] is x[0] to x[n-1]).

If you compile the code with -Wall the compiler should warn you that the array 
is unused, it is not part of the compiler or c++ internals.

I  suggest a quick look at a few C books to pick up the basics before leaping 
into C++ headlong.

Hope this helps
Jon.
