-Parser using bison
++   Lexer using flex
++   Parser using bison
 
 ##How to compile:
-$flex lexer.l
-$bison -d parser.y
-$gcc lex.yy.c parser.tab.c -o parser.out
++   $flex lexer.l
++   $bison -d parser.y
++   $gcc lex.yy.c parser.tab.c -o parser.out
 
 ##How to run:
-$./parser.out < inputStream
-OR:

++   $./parser.out < inputStream
++   OR:
++   $./parser.out inputFile.txt
 
 ##Output:
-stdout for rules and symbo table goes to rule.out and symtable.out
-stderr for rules and symbo table goes to rule.err and symtable.err
++   stdout for rules and symbo table goes to rule.out and symtable.out
++   stderr for rules and symbo table goes to rule.err and symtable.err
