Programming Languages and Compilers - IT Assignment Help

Assignment Task:

1  AA Language
For this phase, you will use the Lex tool for writing the scanner and Yacc tool for writing the parser for a programming language called AA.

The Parser and the Grammar: 

When YACC finds input that doesn’t match the grammar, it automatically termi- nates with the message ’Syntax error’. You will need to implement an error routine (yyerror) that also prints out the line number before this termination, and a main method that read AA code from a file. Print an appropriate message in case of no syntax error. Build your parser using the grammar below: 

• Start→ Program START Statements END 

• Statements → Statements Statement| Statement 

• Statement→ Dec stmt | Assignment stmt | Print stmt | Read stmt | Condition stmt | While stmt 

• Dec stmt→ Type ID |Type ID,IDList 

• IDList → ID | ID,IDList 

• Type→ int | double 

• Assignment stmt→ID = Expression 

• Expression → exp == exp | exp <> exp | exp < exp | exp <= exp| exp >= exp | exp >= exp | exp 

• exp→ exp + exp | exp - exp| exp * exp | exp /exp | exp || exp | exp && exp | !exp | Factor 

• Factor→ ( exp )| INT LITERAL | DBL LITERALL | ID 

• Print stmt→ print ( ID ) | print ( STRING LITERAL ) 

• Read stmt→ ID = read ( ) 

• Condition stmt→ if (Expression ) statements 

• While stmt→ while ( Expression ) statements
