Due: Monday, Feb. 25.
Using Bison, create a parser for the language in the appendix of the text. There is an error in the grammar. The production
factor -> id
should be
factor -> variable
Your parser should just print yes if the program is syntactically correct and no there is a syntax error.
Turn in your assignment using the handin utility. You can do that as follows. Add the line
alias handin5220 '/export/stu/classes/csci5220/bin/handin csci5220'
to your .cshrc file (assuming you are using csh). Then turn in the
lexer (which I am assuming is called lexer.lex) using the following command.
handin5220 3 lexer.lex parser.y
You should receive a notification that the handin was successful. If
not, then it was not successful.
