24. Suppose that you are defining a grammar for scientific notation numbers. (Ex: "1.3e+5"). What are supposed to be the terminals in this language? (Tip: try to use a float point representation using regular expression).
What you need to do:1. Type that code up and run it to make sure that it is doing what it is supposed to do. Provide the strings in the header of the program when prompted.2. Use the logic in that program to design your own Recursive Descent parser in C for the following grammar:S →aABA →Abc | bB →d3. Make sure that you choose at least two strings that pass the grammar and one string that does not pass the grammar just like I did in the model program4. Submit both the code and a screen shot of your results for the choice of strings that you provided. Below is the C code that can be used to implement a Recursive Descent parser for the above grammar/* Recursive Descent Parser for the Expression Grammar:S → (L) |aL' →,SL'|εL → SL'Valid inputs: (a,(a,a)) and (a,((a,a),(a,a)))Invalid inputs:(aa,a)*/#include <stdio.h>#include <string.h>int S(), Ldash(), L();char *ip;char string[50];int main() {printf("Enter the string\n");scanf("%s", string);ip =…
Chomsky Normal Form: Most useful grammars can be translated into a nor-mal form making answers to questions about the language more transparent.
Finish the 2 "TODO" in the ASM Language! A palindrome is a word that is spelled the same way forwards and backwards. For example, "radar", "racecar", "civic", "kayak", and "madam" are all palindromes. The definition can be extended to phrases and sentences when ignore case and punctuation, but for this exercise we will stick to a single word. The starter code provided uses the C library functions printf and scanf to prompt for an input a word. The word that is entered from the keyboard is a null-terminated string placed in the byte array at address buf. There are also two output strings provided at addresses str_is_palindrome and str_is_not_palindrome. The starter code provided simply outputs the string at str_is_not_palindrome. The code contains two TODO comments... At the first TODO comment, the byte array at buf is filled with input from the keyboard. This input is a null-terminated character string (i.e. the array contains the characters entered on the keyboard, followed by ASCII…
1. Use the algorithm described in class that takes a CFG and converts it into a CNF (Chomsky Normal Form) grammar that generates the same language as the original grammar, except possibly for the string A, to answer the following question. As part of your answer, you should say which variables are nullable, and you should give the appropriate grammar after each step of the algorithm. There are four steps. Give a CFG (context-free grammar) in CNF (Chomsky Normal Form) that generates the same language, except possibly for the string A, as the following grammar: SAB AB →bAa A → aaB bb
Create a context-free grammar for the regular expressions. Include in your grammar the basis elements(empty set, empty string, single alphabet symbol), the primitive operators (Union, Concatenation, andKleene-closure), and parenthesized expressions. Include in the grammar nontermimal ⟨s⟩ that mayderive any alphabet symbol.
a. Eliminate Left Factoring from the grammar above. b. Eliminate Left Recursive from the grammar above if there is any.
Q1: Explain the concepts of ambiguity of a grammar. Take an example of your choice and show that the grammar is ambiguous. Draw the parse tree as needed. Q2: Select three flow control statements from C-programming, or from any other programming of your choice, and explain how the relevant grammars are written.
A GOTO statement was recommended not to be used because: a. It can create multiple exit points in blocks. b. It can create multiple entry points in 2 blocks. 3 c. Increases the size of the program d. All the above e. (a) and (b) Question 19 C programming language is considered a. Object Oriented programming languages b. Functional Language c. Low level close to assembly d. None of the above
a. Write a BNF grammar for the language consisting of strings built only of the letters a and b. The strings may have any number of these letters, but the letter combinations bb must be in each string somewhere, and each string must start with a aa. For example, the strings aaabbabbba, aaaababba, and aababbabb are in the language, while a, bba, ababb, aabaa, and bbaa are not. b. Draw the parse tree for string aabbaaba according to the previous grammar: c. Describe, in complete English sentences and “layman’s terms,” the language defined by the following grammar in BNF (start symbol is <S> ): <S>::= <A>a|<B>b <C>::= c <A>::= a<A>a|<C> <B>::= b<B>b|<C>
14. Write a BNF grammar that describes an arbitrarily long string of the characters a, b, and c. The string can contain any number of occurrences of these three letters (including none) in any order. The strings "empty", a, accaa, abcabccba, and bbbbb are all valid members of this language.
Problem 1: Write a regular expression that recognizes the following language over the alphabet {a,b}: Any string containing the letters a and b, where the number of letters is not a multiple of three. (Note that 0 is a multiple of three.) Your regular expression should contain only a and b, and the metacharacters (, ), *, +, ? and |. Problem 2: Write a context free grammar that recognizes language from Problem 1. Your start symbol should be named S.
