Code Challenge: Arrays - Confused!

Declare an array of type 'char' called "letters" with a size of 2. Assign the variable "alpha" as the first element of the array "letters".

This is what I did

char letters[] = {alpha, };

Keeps saying "Make sure you're creating a 'char' array and giving it the correct size. As a reminder, arrays are 'zero-based' and start with 0."

I also tried

char letters[2]; letters[0] = alpha;

But no success, any ideas? :/ (thanks in advance)

Jack

edited my answer. Looks like what you had should have worked. are you sure you had

char letters[2];

letters[0] = alpha;

Did you make sure to keep the code from the first part of the challenge in the code section? Otherwise it will not know what "alpha" is.

I think it would have said that the previous task was no longer passing if that was the case correct?

Just tested it.

It actually does not warn the user that they deleted the previous code, it returns the exact error Jack mentioned

Your code for part 2 should look: char alpha = 'a'; char bravo = 'b';

char letters[2];
letters[0] = alpha;

you should have 

char alpha = 'a';

char bravo = 'b';

char letters[2];

letters[0] = alpha;

letters[1] = bravo;

This helped me a lot too. Initially, I deleted the declarations from the previous question. After struggling a bit I found your posts and all is good. Thanks!
