Is there a work around for invalid octal digit in an array?

Question

I'm trying to create an array which will hold the hours in a day so I can loop through it for a clock.

I have:

int hourArray[24] = {12, 01, 02, 03, 04, 05, 06, 07, 08, 09, 10, 11, 12, 01, 02,
                     03, 04, 05, 06, 07, 08, 09, 10, 11};

I am getting the error on the following numbers in order 08, 09, 08, 09.

It tells me:

Error: invalid octal digit

I've never run into this before and I'm wondering if there is any way around it?

Answer 1

Sure: don't use leading 0s when you don't mean octal:

int hourArray[24] = {12, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 
   1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11};

Don't forget that you're only specifying the numbers in the array - not any particular text representation of the number. (So if you write 012 that's equivalent to writing 10 - you'll end up with the same number.) If you want to format those numbers with a leading 0 later that's an entirely different aspect of the code.
