Compiler Construction @ Hanyang Univ.

Project1

• C-minus scanner implementations.
• The scanner read an input source code string, tokenize it, and return recognized tokens.
• Two version exists.
  • Implementation method1: recognize tokens by DFA.
  • Implementation method2: specify lexical patterns by Regular Expression.

Project2

• C-minus parser implementation using Yacc (bison).
• The parser read an input source code string, tokenize & parse it with C-minus grammar, and return abstract syntax tree (AST).

Project3

• C-minus semantic analyzer implementation.
• Find all semantic errors using symbol table & type checker.
• The semantic analyzer read an input source code string, and generate AST. After that, the semantic analyzer traverses the AST to find and print semantic errors and its line number.
