Nowhere. You should be reading what I post more clearly...

The random function returns an integer, the max value for a 32 bit integer is 2147483647, thus, if you had more than 2147483647 indices, you could not reference a word at index 2147483648 now could you? It was an added bit of info I put in that really has no meaning here since you're not dealing with that many words.

There's nothing bad about it except for when you're trying to read the code later on and you have to look at what the types are. It doesn't do any disadvantage otherwise.

"overuse of var often means that you don't understand what's actually going on" - Not necessarily.

"it makes it harder for others to read, and even makes it harder for you to read if you have to come back to it weeks or months later" - Yes, this is what I initially mentioned.
