No, it's not a mistake. It is perfectly legitimate. He's asking why you
didn't take advantage of one of the conveniences of C. The following code:

	int n;
	n = 1;

Has exactly the same effect as

	int n = 1;

The second form is just a convenience feature - not using it isn't a
mistake, it just means that you typed more code than you needed to. But
you did type more code than you needed to, and that's what he was asking
about.
