So, finally i got a one stop solution of my compiler design examination. Firstly, due to this pandemic, neither we could avail the books nor there were proper video lectures available on youtube to help me out in this subject. One of my friend suggested me this channel and surprisingly, watching the first video of this video series, made me realize that its going to be enough for my complete subject. The way this teacher has explained the concepts, his clear understanding as well as the clear vocalization of the subject had a huge impact. No doubt, this is the best of the series, i have ever watched in terms of Engineering subjects. No words to express my gratitude. Students like me who love to reach in depth of a subject, you have given a one stop solution. I cannot stop ravishing and thanking you "SIR"🤩. God bless😇

id is together. So it means it's a single terminal symbol and not two separate terminal symbols i and d. It means indentifier.

in the last example, first(F) -> first(id) -> id , how? isn't id terminal so the first (id) should have been i ; Is there any special exception or something for id ?
@chirntn Жыл бұрын
Got it - so basically In the context of compiler design and formal grammars, id represents a terminal symbol that stands for an identifier token in the programming language being parsed. In the grammar you provided, the terminal symbol id represents the token for an identifier, which can be any sequence of letters, digits, and underscores that follows the rules of the programming language's naming conventions. Therefore, the FIRST set of id is simply id itself, as it is the only possible token that can start with the id terminal symbol. To clarify, i is a character in the English alphabet, while id is a token in the programming language's syntax. The symbol id is used in the grammar to represent the terminal symbol that matches an identifier token in the language, and it has nothing to do with the character i.

Key takeaways for me - 1) First (terminal) = terminal and First(epsilon) = epsilon 2)For finding first, focus only on the LHS of any grammar 3)if S->ABC, first of S will be first of A ** (This is if A is not producing any epsilon ) 4) if A is producing say a,b,epsilon, Then first(S) will be a,b and also First(B) 5) if S-> Epsilon, then first of S will just be Epsilon ( from point 1)
