## Difference between -> and . in a struct?

If I have a struct like

```struct account {
int account_number;
};
```

Then what's the difference between doing

```myAccount.account_number;
```

and

```myAccount->account_number;
```

or isn't there a difference?

If there's no difference, why wouldn't you just use the `.` notation rather than `->`? `->` seems so messy.

-> is a shorthand for `(*x).field`, where `x` is a pointer to a variable of type `struct account`, and `field` is a field in the struct, such as `account_number`.

If you have a pointer to a struct, then saying

```accountp->account_number;
```

is much more concise than

```(*accountp).account_number;
```

You use `.` when you're dealing with variables. You use `->` when you are dealing with pointers.

For example:

```struct account {
int account_number;
};
```

Declare a new variable of type `struct account`:

```struct account s;
...
// initializing the variable
s.account_number = 1;
```

Declare `a` as a pointer to `struct account`:

```struct account *a;
...
// initializing the variable
a = &some_account;  // point the pointer to some_account
a->account_number = 1; // modifying the value of account_number
```

Using `a->account_number = 1;` is an alternate syntax for `(*a).account_number = 1;`

I hope this helps.
