- Write an EBNF rule that describes the for-statement of Java or C++. Write the recursive descent subprogram in Java or C++ for this rule.Recursive Parsing Calculator HINT: Before attempting this exercise, see the simplerecursiveparser.java in the example programs of the recursion unit on QM+ and the related booklet about Language, grammars and recursion that explains it. Write a program that recursively parses expressions, input as strings, from the following recursively defined language and calculates and prints out the answer to the calculations. Legal expressions in this language involve putting the operator before its arguments (this is called Polish notation). = * | T = 0|1|2|3|4|5|6|7|8|9|A|B|C Instead of writing 3*2, in this language you write *32 (which evaluates to 6). EXP stands for expressions. means multiply the two digits that follow (after evaluation) so *24 is 8 and *5*34 is 60 as it first multiples 3 and 4 to get answer 12 then multiplies 5 and 12 to get 60. Tn means add the next 3 numbers from n (so eg T3 means 3+4+5=12, T7 means 7+8+9-24), DIGIT gives a way to express numbers up to 12 as a sıngle…Recursive Syntax The recursive structure i.e of natural language like English can be expressed in syntax rules written in the format known as BNF (Bachus-Naur Form). While BNF is ordinarily used as a guide for parsing (that is, determining whether and how a given string follows the syntax rules), An example of this can be found in the sample program SimpleRandomSentences. You should write a similar program that implements the following rules:<sentence> ::= <simple_sentence> [ <conjunction> <sentence> ]<simple_sentence> ::= <noun_phrase> <verb_phrase><noun_phrase> ::= <proper_noun> |<determiner> [ <adjective> ]. <common_noun> [ who <verb_phrase> ]<verb_phrase> ::= <intransitive_verb> |<transitive_verb> <noun_phrase> |is <adjective> |believes that <simple_sentence><conjunction> ::= and | or | but | because<proper_noun> ::= Fred | Jane | Richard Nixon | Miss…
- Java Assignment: Experiment with naming rules in Java Does the language use static or dynamic scoping? Can scopes nest? Are they open or closed? Does the scope of a name encompass the entire block in which it is declared, or only the portion after the declaration? How does one declare mutually recursive types or subroutines? Can subroutines be passed as parameters, returned from functions, or stored in variables? If so, when are referencing environments bound? Justify your answers with suitable code snippet and its output.Can you please help me solve this in C language? I did encounter and solve this problem with Java but I cannot seem to implement the use of structures in solving this problem. Help is appreciated, thank you. Using the concept of structures, write a program to assign passenger seats in an airplane. Assume a small airplane with seats numbered as follows: 1 A B C D 2 A B C D 3 A B C D 4 A B C D 5 A B C D The program should display the seat pattern, marking with an ‘X’ the seats already assigned. For example, after seats 1A, 2B, and 4C are taken, the display should look like: 1 X B C D 2 A X C D 3 A B C D 4 A B X D 5 A B C D Seats are assigned by specifying a number and a letter. If the user types in a seat that is already assigned, the program should say that the seat is occupied and ask for another choice. The program should run until all seats are…Part 2: Recursive Fractals Examine this pattern of asterisks and blanks, and write a recursive function called pattern() that can generate patterns such as this: pattern(3, 2); pattern(5, 1); pattern(7, 0); With recursive thinking, the function needs only about 10 lines of code (including two recursive calls). Your function prototype should look like this: // Description: I/ The longest line of the pattern has n stars beginning in column col of the output. // Precondition: n is an positive odd number. // Postcondition: A pattern based on the above example has been printed. void pattern (int n, int col); No error handling needed for this part. Assume that user will provide you a positive odd int as n, and a non-negative int as col. Hint: Think about how the pattern is a fractal. Can you find two smaller versions of the pattern within the large pattern? Here is some code that may be helpful within your function: // A loop to print exactly col columns for (int i = 0; i < col; i++) cout <«…
