I kept the photos as a single reference page: how compilation is staged, how today’s languages relate historically, and where <strong>syntax</strong> stops being enough — you need <strong>precedence rules</strong>, <strong>disambiguation</strong> for things like <code>else</code>, and <strong>attributes</strong> for semantics such as types.</p> <h2 id="compiler-pipeline">Compiler pipeline</h2> <p>The usual story: <strong>source program</strong> → <strong>lexical analyzer</strong> (tokens) → <strong>syntax analyzer</strong> (parse trees) → <strong>intermediate code</strong> (with <strong>semantic analysis</strong>) → optional <strong>optimization</strong> → <strong>code generator</strong> → <strong>machine code</strong> on a <strong>computer</strong>, plus <strong>input data</strong> and <strong>results</strong>. A <strong>symbol table</strong> sits beside the front phases and feeds the back end.</p>
