Struct/typedef

What's the difference between

Code:

---

typedef struct // about this line
{
        int val;
        struct ll * next;
} ll;

---

and

Code:

---

struct ll  // about this line
{
        int val;
        struct ll * next;
} ll;

---

? They both compile fine.

The first one creates an anonymous struct (without any name) and typedefs it to the type "ll".
The second one creates a struct called "ll" an initializes one struct called "ll".

The first one is equal to:

Code:

---

struct someStruct {
        int val;
        struct ll * next;
};

typedef someStruct ll;

---

the second one is equal to:

Code:

---

struct ll  // about this line
{
        int val;
        struct ll * next;
}

struct ll ll;
