Form the description it is clearly stated that KEYWORD is a Marco for list of keywords.
Based on the regular expression
<YYINITIAL> { KEYWORD} {keyword++;}
the value for keyword is the list of keywords defined by the macro KEYWORD.
<YYINITIAL> [a-zA-Z] [a-zA-Z0-9] * {id++;}
Thus the value of id can start with only alphabets and can contain a combination of alphabets and numbers.
The following questions are relevant to assignment A2. Suppose that KEYWORD is the macro that defines...
Your mission in this programming assignment is to create a Python program that will take an input file, determine if the contents of the file contain email addresses and/or phone numbers, create an output file with any found email addresses and phone numbers, and then create an archive with the output file as its contents. Tasks Your program is to accomplish the following: ‐ Welcome the user to the program ‐ Prompt for and get an input filename, a .txt...
please Answer the following regular expressions questions(also do number 9) Q4 Choose the pattern that finds all filenames in which the first letters of the filename are astA, followed by a digit, followed by the file extension .txt. 1) astA[[:digit:]]\.txt 2) astA[[0-9]].txt 3) astA.\.txt 4) astA[[:digit:]].txt Q5 What's the difference between [0-z]+ and \w+ ? 1) The first one accepts 0 and z and the other doesn't. 2) The first one doesn't allow for uppercase letters. 3) The first one...

The first project involves modifying the attached lexical analyzer and the compilation listing generator code. You need to make the following modifications to the lexical analyzer, scanner.l: 1. A second type of comment should be added that begins with // and ends with the end of line. As with the existing comment, no token should be returned. 2. The definition for the identifiers should be modified so that underscores can be included, however, consecutive underscores, leading and trailing underscores should...
Assignment Overview In Part 1 of this assignment, you will write a main program and several classes to create and print a small database of baseball player data. The assignment has been split into two parts to encourage you to code your program in an incremental fashion, a technique that will be increasingly important as the semester goes on. Purpose This assignment reviews object-oriented programming concepts such as classes, methods, constructors, accessor methods, and access modifiers. It makes use of...

python 3 question Project Description Electronic gradebooks are used by instructors to store grades on individual assignments and to calculate students’ overall grades. Perhaps your instructor uses gradebook software to keep track of your grades. Some instructors like to calculate grades based on what is sometimes called a “total points” system. This is the simplest way to calculate grades. A student’s grade is the sum of the points earned on all assignments divided by the sum of the points available...

Goal: Your assignment is to write a C+ program to read in a list of phone call records from a file, and output them in a more user-friendly format to the standard output (cout). In so doing, you will practice using the ifstream class, I'O manipulators, and the string class. File format: Here is an example of a file...
Java Project For this assignment, you will write a simulation program to determine the average waiting time at a grocery store checkout while varying the number of customers and the number of checkout lanes. Classes needed: SortedLinked List: Implement a generic sorted singly-linked list which contains all of the elements included in the unsorted linked list developed in class, but modifies it in the following way: delete the addfirst, addlast, and add(index) methods and instead include a single add method...
