How does a computer understand if (x > 5)? It doesn't. It only understands
voltage. A Compiler is the bridge that translates human-readable code into machine-executable binary.
This course demystifies the magic of programming languages—you will learn how to build a parser,
optimize code, and how high-level logic becomes low-level instructions.
Designing your own domain-specific language (DSL) or configuration file parser.
Understanding how compilers make your code faster (Dead Code Elimination, Loop Unrolling).
How VS Code highlights syntax errors and provides auto-complete (Lexical & Syntax Analysis).
What: Covers Compiler Phases, Symbol Tables, and Lexical Analysis (Regex/DFA).
Why: The first step is reading the text. Lexical analysis groups characters into "Tokens" (words), just like your brain reads letters as words.
What: Covers Grammars, Top-Down (LL), and Bottom-Up (LR, SLR, CLR, LALR) Parsers.
Why: Parsing ensures the "words" form valid sentences. It's how the compiler knows you missed a semicolon.
What: Covers Syntax Directed Translation (SDT), Type Checking, and Three Address Code (TAC).
Why: Semantic analysis checks for meaning—ensuring you don't add a String to an Integer. TAC is the machine-independent intermediate step.
What: Covers Runtime Environments, Stack Frames, Basic Blocks, and Data Flow Analysis.
Why: Understanding how the compiler allocates memory and optimizes code explains why compilers often write better assembly than humans.
What: GATE-style problems on parsing tables, grammar manipulation, and optimization.
Why: Constructing LR tables manually is the best way to understand the complex logic behind automatic parsers.
