The compiler reads the source code as a stream of characters and groups them into meaningful units called .

Just because code is grammatically correct doesn't mean it makes sense. The semantic analyzer checks for "meaning." compiler construction principles and practice

While LALR(1) parsers (Yacc, Bison) are powerful, they produce cryptic error messages. The industry practice for educational compilers or scripting languages leans toward hand-written recursive descent parsers (used in GCC, Clang, and Rust). The compiler reads the source code as a
