PL Week 5 (Oct 5+8): From Source Code to Execution

How does source code become a running program? This episode follows the full pipeline: implementation methods — compilers, interpreters, and hybrids (1.7); describing syntax with grammars, parse trees, and ambiguity (3.1–3.2); the key ideas of lexical and syntax analysis (4.1); and what "meaning" looks like at runtime, through an assignment statement in operational semantics (3.5).
