on code challenge for objective-c basics it says " 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". " but i have no clue how to go about this as it does not show you how to do more than just one char variable?

datatype variableName = value;
to declare two variables:
datatype variableNameOne = value;
datatype variableNameTwo = value;
so to declare two char variables
char nameOne = 'x';
char nameTwo = 'z';
That should help you out quite a bit.

42,016 PointsPeter Hearne, to declare an array with a certain size:
datatype arrayName[x];
replace the x with the size you want the array to be
char myArray[2];
to access the first element of an array and assign it a value (remember array indexes start at zero):
myArray[0] = value;
accessing the second element is the same except you use 1 instead of 0.

6,803 Pointsthank you so much, there is another question that im unsure about " 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". " i am unsure how to declare an array and size it, and how to assign "alpha" as the first element of array "letters"
