Hi, I am having trouble understanding part of this code below. I explain my problem below the code. Any help greatly appreciated. I have previously posted this post here.
other post But still have questions. The problem code snippet is in bold.
I don't understand what this line is for
it looks like it points to the lets say E-A position which would be 4, then ++ that which is 5, but I don't know what it is for? please.
I guess bold doesn't work in code mode.
I also don't understand how this outputs the number of letters for each index
System.out.println (": " + lower[letter]);
