3. Given the following grammar and the right sentential forms, draw a parse tree and show...
3. Using the grammar below, show a parse tree and a leftmost derivation for the statement. A = ( A + (B)) * C assign <idxpr expr>? <expr> <term> term <term factor factor (<expr>) l <term I <factor l <id> 4. Prove that the following grammar is ambiguous (Give sentence that has two parse trees, and show the parse trees):
- Using the grammar in Example 3.2, show a parse tree and a leftmost derivation for the following statement: B = C * (A * (B + C)). EXAMPLE 3.2 A Grammar for Simple Assignment Statements <assign> → <id> = <expr> <id> → A | B | C <expr> → <id> + <expr> | <id> * <expr> | ( <expr> ) | <id>
Consider the following grammar G: S → 0S1 | SS | 10 Show a parse tree produced by G for each of the following strings: 1. 010110 2. 00101101
Use the grammar given below and show a parse tree and a leftmost derivation for each of the following statements. 1. A = A * (B + (C * A)) 2. B = C * (A * C + B) 3. A = A * (B + (C)) <assign> → <id> <expr> = <expr> → <id> + <expr> kid<expr> <expr>) ids
1) Using the grammar in Example 3.2, show a completed parse tree for each of the following statements: a) A = A * (B + (C * A)) b) A = A * (B + (C)) 2) Using the original grammar in Example 3.4, show a completed parse tree for the statement: A = B + C + A A Grammar for Simple Assignment Statements PLE 3.2 cassign><id> <expr> cidA BIC «ехpг» — sid + <ехpг» id cexpr> ( <expr>)...
For the grammar and each of the strings, give the parse tree. Exercise 5.1.2: The following grammar generates the language of regulair expression 0'1(0 1): SA1B * а) 00101. Ь) 1001. с) 00011.
The following grammar describes the syntax of the Java if statement: <stmt> rightarrow <matched> | <unmatched> <matched> rightarrow if (<logic_expr>) <matched> else <matched> | <non_if_stmt> <unmatched> rightarrow if (<logic_expr>) <stmt> | if (<logic_expr>) <matched> else <unmatched> Using this grammar, draw a parse tree for the following sentential form: if (<logic_expr>) if (<logic_expr>) <non_if_stmt> else <non_if_stmt>
6. (8 pts) Using grammar below show a Parse tree and leftmost derivation for a). A = A * (B+C) <assign> à<id> = <expr> <id> à A | B|C <expr>à <expr> + <term> | <term> <term> à <term> * <factor> |<factor> <factor> à ( <expr> ) |<id>
Question Set 2 1. Given the following grammar dactor>-> ( <expr> ) a) What is the associativity of each of the operators? What is precedence of the operators? Show a leftmost derivation and parse tree for the following sentence: b) c) A-A(B(C A)) d) Rewrite the BNF grammar above to give precedence over and force to be right associative.
