C++ referencing an array of structs -


i'm new using c++ complicated programming. i've been sifting through leftover, uncommented, academic code handed down through department, , i've stumbled across have no real idea how google for. don't understand syntax in referencing array of structs.

here trimmed version of i'm struggling with:

typedef struct {     double x0,y0;     double r; } circle;  double foo() {     int n = 3;     double mtt;     circle circles[n];      (int = 0; < n; i++)     {         mtt += mtt_call_func((circles+i), n);     }      return mtt; }

what (circles+i) mean in case?

edit: function should have (circles + i), not (circle + i).

circles+i equivalent &circles[i]. that's how pointer arithmetic works in c++.

why there pointer? well, when give name of array, in context other &circles or sizeof circles, temporary pointer created points first member of array; that's code works with. arrays second-class citizens in c++; don't behave objects.

(i'm assuming circle+i typo circles+i others suggested)
