Help OBJECTIVE-C basics arrays challenge 4/4

Print the results. Your output should look like "letters a b".

char alpha = 'a'; char bravo = 'b'; char letters[2]; letters[0] = alpha, letters[1] = bravo; printf("letters a %c",bravo);

I did this exact code in a compiler and it came up perfect thought the treehouse says: Bummer! That was the correct string, but not the correct format.

thanks 2 anyone who replies!

You're nearly there, just a small error in the last line of your code. You need to print out the value of alpha rather than just 'a'. 

char alpha = 'a'; 
char bravo = 'b'; 
char letters[2]; 
letters[0] = alpha, letters[1] = bravo; 
printf("letters %c %c", alpha, bravo);

I noticed on this new Objective-C course and Code challenges on Arrays from Mr. Turner that “char” was not addressed in the video or how to use “char” correctly. I see that there are many ways to initialize/assign int, floats, and char’s but it never got addressed in this arrays section of learning. I wish this class on Objective-C they would talk about a subject in depth so we beginners would have a better idea so we can pass the code challenge really knowing the topic then struggling and looking for the answer because it was not taught in this video for a few days to find the answer. My main point is to learn the topic in depth and know it. I don’t mind if I have to watch the video many time until I get it, but when you don’t teach us, how am I supposed to know all this additional information for this is a beginners class. Please note that I have the upmost respect and praise for the Treehouse team. I just want to learn the most I can. Is the old Objective-C class available for download so beginners can learn more about Objective-C even though is old?

Thank you Treehouse.
