Stuck on the "Arrays" assignment One.

Hi, i tried declaring the variables alpha and bravo the way i first learned, but it's not working. So, since i'm learning about arrays, i tried two separate array declarations. That didn't work either. Here is the assignment, and my answer. Declare 2 separate variables of type char named "alpha" and "bravo". Assign the letter 'a' to the variable "alpha" and the letter 'b' to "bravo". Answer: char alpha[] = {a}; char bravo[] = {b};

My first answer was: char alpha = 'a'; char bravo = 'b';

Hopefully i just forgot some stuff since yesterday.. Thanks,

hmmm if you had 

 char alpha = 'a';

 char bravo = 'b';

first I would think that would have worked for the first part of the challenge. Try that again and see if it works

Hi, yes, after typing my forum post, i pressed check work, and it went through. But now, i'm stuck again.

Here is the challenge: 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". Here is my answer: char letters[1] = {'alpha',};

I hope it works soon. Haha, getting frustrated that i may not be doing so well at programming. :(

You did not declare your array first before modifying it, which would look like

char array[2];

Assigning the value of a variable to another variable usually looks something like this

datatype varName = otherVarName;

Treat the first element of the letters array as the left side, and then you simply have your alpha variable name as the left. Also remember array indexes start at zero, not 1. So to assign the first element of some array of characters the value of some variable would look like this

array[0] = yourVarName;

Oh, i was using the 1, as the total size of the array, not where i would start! Thanks so much. ^^

Also, to make code blocks on the forum, i use markdown?

There are many ways to markdown your code, but the simplest is to start a new line and then indent your line of code 4 spaces.

I finished the assignment. Thanks bunches! :)

Should i follow along in Xcode as I watch, or watch first, and duplicate after? Want to be efficient. xD
