Well it's full of stylistic problems.

This is mis-idented.

That empty line before this assignment is spurious.

That empty line is unnecessary, remove it.

You can't possibly tell me that this indentation looks right
to you.

You must style things like this:

	if (condition1 &&
	    condition2)

That is, you must line up the first character on the second and
subsequent lines at the first column after the openning parenthesis of
the first line.
