Not sure how to do challenge

Challenge task 2:

"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"."

char alpha; alpha = 'a';

char letters[2]; letters[0] = 'a';

you are almost right. It states "Assign the variable "alpha" as the first element of the array "letters".""

you have 

letters[0] = 'a';

which assigns 'a' to the first element of letters, but what you need to do is assign the variable alpha to the first element of the array letters

letters[0] = alpha;

I tried that, but it does not work.

I originally wrote the following code but it did not work either:

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

are you sure? I just tried the challenge and got it to work. Here is my complete code:

char alpha = 'a';

char bravo = 'b';

char letters[2];

letters[0] = alpha;
