Please I need help with #6 and #7.

In #7 put the variable in defVar

In this programming assignment, you will be building a parser for the Simple Perl-Like (SPL) programming language. The syntax definitions of SPL programming language are given below using EBNF notations. Your implementation of a parser to the language is based on the following grammar rules specified in EBNF notations. 1. Prog ::= StmtList 2. StmtList : := Stmt ; { Stmt; } 3. Stmt : := AssignStme | WriteLnStmt | IfStmt 4. WriteLnStmt ::= writeln (ExprList) 5. IfStmt : := if (Expr) \\{ 'StmtList '}' [ else ' { ' StmtList '}' ] 6. AssignStmt : := Var = Expr 7. Var : := NIDENT | SIDENT 8. Exprlist : : = Expr { , Expr } 9. Expr : := RelExpr [ (-eql==) RelExpr ] 10. RelExpr : : = AddExpr [ ( -it | -gt | ) AddExpr ] 11. AddExpr :: MultExpr { ( + | - ( .) MultExpr } 12. MultExpr : : = ExponExpr { ( * | / | **) ExponExpr } 13. ExponExpr : := UnaryExpr { ^ UnaryExpr } 14. UnaryExpr : := [( - | + )] PrimaryExpr 15. PrimaryExpr : := IDENT | SIDENT | NIDENT | ICONST | RCONST | SCONST (Expr)
