I am just starting out on pset5 reviewing the speller.c code. Looks pretty straightforward however I don't entirely understand the following variable declaration:
char word[LENGTH + 1];
So I understand it is creating an array of chars called word of size LENGTH + 1.
My question is, where does LENGTH come from? I don't think LENGTH has been defined elsewhere in the code and it doesn't seem to be a reserved word either.
What it it doing and how?
