Auto calculation of array size

Dear all,

For some reason, I need to declare an array like that

#define STRING2_DESCRIPTOR_LENGTH 16
BYTE code product_string_descriptor[] = {
	STRING2_DESCRIPTOR_LENGTH,
	0x03,
	'U', 0x00,
	'S', 0x00,
	'B', 0x00,
	' ', 0x00,
	'H', 0x00,
	'U', 0x00,
	'B', 0x00
};

When I add characters to the array, I also need to increase STRING_DESCRIPTOR_LENGTH manually.
Do you know some way to calculate the size of the array automatically?
I know in assembly, I can do something like that

product_string_descriptor:
	DB	end - $
	DB	0x03,
	DB	'U', 0x00
	DB	'S', 0x00
	DB	'B', 0x00
	DB	' ', 0x00
	DB	'H', 0x00
	DB	'U', 0x00
	DB	'B', 0x00
end:

How about in C?

Hi Andy,

The reason for me to post this question is that I think if I am able to do it in C, my strength is getting stronger than before. Just like when you are learning Mathematics, will you feel better if you know more than one solution for some questions than the other?
