I'm planning to add this section. If you have words that you don't know what they mean then tell me! I will add things here as I go along.
immutable
I don't know what this means, but one reader said, "I think it means that once declared, it is permanent and cannot be changed. I will have to look it up in the Websters later. Kind of like your article on References and how they are "immutable". Assign them when you declare them or else you are stuck and will need to recreate the reference. I guess "permanent" would work too but after seeing it a bunch of times, immutable does have a centain ring to it."
pass by value/reference
All variables have two things: a memory address and a value (you should have gotten that knowledge from here). When you pass by value you're passing that variable's value (makes sense, huh?). When you pass by reference you're passing that variable's memory address.
literal
"A string is sometimes called a character string, a message or a literal." - C How To Program (second edition), pg. 25
