2. Using the grammar E-> E+T E-> T T-> id T-> number T-> (E) a. Give a derivation and draw a parse tree for a + b + (c+d). Derivation: F can women w

I need help writing a C++ code. I need help writing a function that accepts a C-string as an argument and returns the number of words contained in the string. Let's say the string argument is "Howdy Partner" the function should return the number 2. Demonstrate the function in a program that asks the user to input a string and then pass it to the function. The number of words in the string should be displayed on the screen.

4.- Simplify the following grammar. Simplify the following GCL S-A JAA|AAA A → ABa | ACa | a B > ABa|Ab| A C> Cab |CC D→ CD |Cd|CEa E > b

I need explanation for this question ? I know the answer but how it, I don't know

Don't copy anyother's work

Consider the context-free grammar below that generates mathematical expressions (it uses "a" as a placeholder for where values would go). S' → S$ S→ BA A→+BA|-BA|A В > DC C→ *DC | /DC |1 D→ a|(S) The non-terminals in this grammar are S', S, A, B, C, and D. The terminals are a, +, -, *, /, (, ), and $. For grading purposes, list terminals in your answers in the following order: a+-*/()$ For each production, list which next input symbol would predict the production (assuming that the production's left-hand side is on the top of the parsing stack). You should find your answer by building a prediction table as seen in class. In each answer list your set in the order given above. If a set is empty write exactly the word empty. Separate items using commas and no spaces. For example: a,-,/,) S → BA { A→ +BA { } A→ -BA { A→1{ В > DC { } C→ *DC { C→ /DC { C → { D→a|(S) { D→ (S) {

The following is a context-free grammar G: V={A,B,S} S={a,b} v0=S S->A A a|b|A B A->B S a|a B->B a | epsilon Convert G into a CFG in Chomsky normal form

Hello I. Need help in theoretical computer science Subtask (a) Let G be a context-free grammar with the start variable S and the following rules, which describes a language using the alphabet Σ = {0, 1}. Show that almost all words in the language described by this grammar are 4-inflatable.
