Writing a compiler teaches you exactly how code interacts with CPU architecture and memory.
Focuses on syntax-directed translation, three-address codes, and type checking.

Learn how compilers store variable names, types, and scopes efficiently. 4. Intermediate Code Generation (ICG)
Modern compilers are divided into two primary parts: the (analysis) and the Back End (synthesis). These parts are further broken down into several distinct phases. Understanding these phases is crucial for mastering compiler construction. Writing a compiler teaches you exactly how code

The lexical analyzer reads the raw stream of characters from the source program and groups them into meaningful sequences called lexemes. These lexemes are translated into tokens, which are then passed to the next phase. It also removes comments and whitespaces. 2. Syntax Analysis (Parsing)
