Parser-for-a-Grammar

Developed a parser/lexical analyzer in java to assess string entered for a particular grammar.

Grammar Tested

1. <program> -> begin <statement_list> end
2. <statement_list> -> <statement> {;<statement_list>}
3. <statement> -> <assignment_statement> | <loop_statement>
4. <assignment_statement> -> <variable> = <expression>
5. <variable> -> identifier (An identifier is a string that begins with a letter followed by 0 or more letters and/or digits)
6. <expression> -> <variable> { (+|-) <variable>}
7. <loop_statement> -> loop (<logic_expression>) <statement>
8. <logic_expression> -> <variable> (< | >) <variable> (Assume that logic expressions have only less than or greater than operators)
