- In Java, it is customary to provide______ method to provide a string representation of an object in a given class.Computer Science Use the Python PLY library to write a parser for the following grammar. You may assume variables A, B, and C are either integers, float, or strings. To simplify your work, assume that these variables have the same data type (choose one: integer, float, string). <program> → begin <stmt_list> end<stmt_list> → <stmt> | <stmt> ; <stmt_list><stmt> → <var> = <expression><var> → A | B | C<expression> → <var> + <var> | <var> - <var> | <var> Do the code pleaseLanguage is c++ Assignment 6 C: Minesweeper - Simplified. For many years, computers sold with the Windows operating system would contain a game called M inesweeper. The player would be presented with a grid, where they would have to click an empty part of the map. If they clicked on a hidden mine, the game would be instantly over. However, if they clicked a safe spot, a hint about nearby mines would be displayed and the player would click another spot. The goal would be to flag all the hidden mines without hitting one. (As an aside, many people did not know these rules and just clicked around randomly until they hit a mine)We will be developing a simplified version of this game. You will prompt the user for a grid size and then created a 2D array with equal width and height (C++ students: Check the Appendix for more information on how to do this). You will initialize the 2D char array with each element equallying a ‘?’ symbol. You will then randomly generate one “mine” value per…
- Write a program in C++ object oriented programming Create a class Class1 with a string data member ‘paragraph’. Provide a constructor and getParagraph() method in the class. The constructor just assigns NULL to the data member. getParagraph() method must read a paragraph from user. The paragraph should contain at least 30 words. If there are less than 20 words, the program must ask user to enter paragraph again. Create another class Class2, and make it a friend of the class Class1. Provide a function getSubString(Class1 &obj1, int startIndex, int lastIndex) with return type string in the class Class2 which accepts an object of class Class1 (by reference) and two integers. The getSubString() function should return the substring starting from location startIndex and ending at location lastIndex. Class2 must also contain a store() function that stores the substring in a file. Print screenshot of substring stored in file as well. (Topics covered: File Handling, Friend Classes.9. It is required to write a parser for the grammar below. <source_file> ::= <declarations> <code> <declarations> ::= vars <list_of_variables> ; <list_of_variables> ::= <variable> | <list_of_variables> , <variable> <code> ::= <statements> . <statements> ::= <assignment> | <statements> ; <assignment> <assignment> ::= <variable> := <expression> <expression> ::= <expression> + <term> | <expression> - <term> | <term> <term> ::= <term> * <factor> | <term> / <factor> | <factor> <factor> ::= <number> | <variable>C++ PROGRAMMING Create a C++ program that accepts an English sentence and converts it to Pig Latin. The rules of Pig Latin are as follows: If the word starts with a vowel, add the word "yay" in the end. If the word starts with a consonant, move the first letter of the word in the end and add "ay" in the end. If the word starts with a capital letter, follow the rule and convert the first letter of the converted Pig Latin word into a capital letter. (i.e. Hello -> ElloHay) If there are numbers in the sentence, they should not be translated. A word with a combination of letters and numbers will not be tested. Spacing and punctations must be preserved. Sample Input: A quick brown fox jumps over the 100 lazy dogs. Expected Output: Ayay uickqay rownbay oxfay umpsjay overyay hetay 100 azylay ogsday.
