Objective C Basics - Code Challenge Arrays

For some reason I can not understand what question #4 is looking for here. This is what I have for the question: Print the results. Your output should look like "letters a b".

char alpha;
alpha = 'a';
char bravo;
bravo = 'b';

char letters[ ] = {a, b};

printf("letters %c %c", letters[0], letters[1]);

It keeps giving me an error saying to remember the correct format character for char is %c

Any ideas what I am doing wrong?

Your code is mostly right. Except you need to assign the variables alpha and bravo when creating the letters array. Not sure where you are getting a and b from.

I did have that line as: char letter[2] = {alpha, bravo};

however that does not work either. So I decided to sue another format all together and go with the letters [ ] and call out the a and the b. Still can not get it to work either way I do. It just calls out that %c is the correct format. Any other ideas?

char letters[2] = {alpha, bravo}; should work. I just tried it. You had letters misspelled.

I did put in exactly how you have it and keep having this """Bummer! Make sure you're creating variables of type 'char' and setting them to the correct values."""
