CParser().parse parses C99 source declarations into a typed FileAST hierarchy preserving source coordinates and declaration types.
Subclassing c_ast.NodeVisitor with visit_<NodeType> methods traverses AST nodes and collects syntactic constructs like function definitions and binary operators.
CGenerator().visit formats an AST tree back into valid C source text.
Parsing malformed C syntax raises c_parser.ParseError with descriptive failure diagnostics.
