Description of the language as follow: Detail Note #DEFINE // define is keyword DEFINE / Nothing Reserve words CONST, FLOAT , INT, BREAK, CONTINUE , ELSE , FOR , SWITCH, VOID, CASE, ENUM , SIZEOF, TYPEDEF ,CHAR ,DO, IF, RETURN, UNION, WHILE, GIFT, DEAN, HOD, and, #INCLUDE // include is keyword INCLUDE // Nothing " cannot be an identifier. cannot be last symbol of id. Must have one or more digit. or Identifiers examples (vallu e, r2ate, Clo_unter, 2test123, etc Can start with Digit.

Source code should reflect the detail given in documents (other parts). 2. A text file with valid source code will be input of the scanner and Token file will be output of the scanner tool. 3. All points discussed in the class related to scanner implementation should reflect in the assignment. 4. Application should not do which is not supposed to do.
