Uses Finite Automata (DFA/NFA) and Regular Expressions . Goal: To identify valid "words" in the language. 🌿 Phase 2: Syntax Analysis (Parser) Input: Tokens. Output: Parse Tree or Syntax Tree. Logic: Uses Context-Free Grammar (CFG) . Goal: To check the grammatical structure of the code. 🧠Phase 3: Semantic Analysis Task: Checks for logical errors (e.g., type mismatch). Output: Annotated Parse Tree.
He finished with ten minutes to spare. Looking around, he saw others sweating over their calculators. He felt a surge of gratitude for the group. They didn't just study for GATE; they mastered the machine. compiler design gate smashers
: Produces a platform-independent code (e.g., Three-Address Code). Code Optimization Uses Finite Automata (DFA/NFA) and Regular Expressions
Consider grammar: E → E + T | T T → T * F | F F → id Output: Parse Tree or Syntax Tree
