Structures within Structures

I am having trouble accessing structure members within Structures.

I have two structures:

Code:

---

struct path {int tour[T]; double overall_cost;};

struct ant {int numb; struct path; int rank;};

---

When i use a pointer to ant to access the array pointer inside the structure path I use the following:

Code:

---

ant_ptr->path->tour[i]=j;

---

However this doesn't seem to work, Any ideas?

The second -> should be just .

Code:

---

struct path {int tour[T]; double overall_cost;};

struct ant {int numb; struct path; int rank;};

---

You still need to declare what will hold path (ie a variable), something like:

Code:

---

struct path {
    int tour[T];
    double overall_cost;
};

struct ant {
    int numb;
    struct path p;
    int rank;
};

---

And access it through,

Code:

---

ant_ptr->p.tour[i] = j;
