Augment the following BNF to write an attribute grammar. Assume the only possible variable types are integer and float. The language rules are as follows:
1) The types of variables in an expression do not have to be the same. The type of the expression result is that of the first (or leftmost) variable in the expression.
2) If the type of variable to be assigned is integer, the type of the expression must be integer.
3) If the type of variable to be assigned is float, the type of the expression can be integer or float.
<assign> → <var> = <expr>
<expr> → <var> + <var>
<expr> → <var> - <var>
<expr> → <var>
<var> → A | B | C

1. In a language, each sentence is a string starting with a capital letter followed by two or more small letters and ending with three or more digits. Example sentences are Abc001, Zyxw9876 etc. a) Write a BNF grammar for the language. b) Show the derivation and the parse tree of the string Test3501. 2.

Consider the following grammar for variable and class
declarations in Java:
<Decl> -> <VarDecl>
| <ClassDecl>
<VarDecl> -> <Modifiers> <Type> <VarDec> SEM
<ClassDecl> -> <Modifiers> CLASS ID LBRACE <DeclList> RBRACE
<DeclList> -> <Decl>
| <DeclList> <Decl>
<VarDec> -> ID
| ID ASSIGN <Exp>
| <VarDec> COMMA ID
| <VarDec> COMMA ID ASSIGN <Exp>
Indicate any problems in this grammar that prevent it from being
parsed by a recursive-descent parser with one token lookahead. You

Consider the following context free grammar. Write an attribute grammar that specifies the calculation rules, i.e. how the value of E or T is calculated. There is no need to perform type checking. We assume all types are matched correctly. Please clearly specify the type of attribute(s) you introduce, i.e. synthesized, inherited, or intrinsic. E ::= E + T | T T ::= T * F | F F ::= NUM NUM ::= 1 | 2 | 3 | 4...

Write a parser program for cSub using the method of recursive descent. The main program here will effectively be the main program of the compiler as a whole. The input to the program will be a Csub source file, specified on the command line. The program will construct a parse tree for the program, with one interior node for every nonterminal in the derivation of the program, and one leaf node for each of the id, num, and real tokens...
