- TASK: Build a simple shell.DESCRIPTION:Write a shell program in C similar to "csh" that takes commands from thekeyboard. In particular, your shell prompt must be the current time(instead of, say, % as is common in UNIX).Make it simple; that is, do not allow it to handle background processes,it can ignore the control-C key, and especially, do not design it tointerpret shell scripts.You will need the following system calls:forkwaitpidone of execv, execve, execvp (read the manual pages).You must NOT use the C library function "system".Which statement of the following is the most appropriate? Group of answer choices You don’t have to write every container class from scratch. The C++ Standard Template Library (STL) provides couple container classes that are useful in some settings. You may have to write every container class from scratch. The C++ Standard Template Library (STL) does not provide any container classe. You don’t have to write every container class from scratch. The C++ Standard Template Library (STL) provides four container classes that are useful in many different settings. You don’t have to write every container class from scratch. The C++ Standard Template Library (STL) provides a variety of container classes that are useful in many different settings.Focus on string operations and methods You work for a small company that keeps the following information about its clients: • first name • last name • a 5-digit user code assigned by your company. The information is stored in a file clients.txt with the information for each client on one line (last name first), with commas between the parts. For example Jones, Sally,00345 Lin ,Nenya,00548 Fule,A,00000 Smythe , Mary Ann , 00012 Your job is to create a program assign usernames for a login system. First: write a function named get_parts(string) that will that will receive as its arguments a string with the client data for one client, for example “Lin ,Nenya,00548”, and return the separate first name, last name, and client code. You should remove any extra whitespace from the beginning and newlines from the end of the parts. You’ll need to use some of the string methods that we covered in this lesson You can test your function by with a main() that is just the function call with the…

This unit test should use the attributes and methodsI need help with this one please, already tried but still getting a wrong answer Scenario You have been tasked with building a URL file validator for a web crawler. A web crawler is an application that fetches a web page, extracts the URLs present in that page, and then recursively fetches new pages using the extracted URLs. The end goal of a web crawler is to collect text data, images, or other resources present in order to validate resource URLs or hyperlinks on a page. URL validators can be useful to validate if the extracted URL is a valid resource to fetch. In this scenario, you will build a URL validator that checks for supported protocols and file types. Task Create two lists of strings – one list for Protocol called valid_protocols, and one list for storing File extension called valid_fileinfo. For this take the protocol list should be restricted to http, https and ftp. The file extension list should be .html, .csv and .docx. Split an input named url, and then use the first…

Somehow the vote tallies for sophomore and junior class presidents got mixed up! Your method should accept as its parameter a Scanner representing a file of vote results. It should output the next sophomore and junior class presidents. The file format looks like the following: Jared s 25 Sophie j 12 Tom j 44 Isaac s 30 Emily s 60 Russ s 23 Madison j 20 The file repeats the pattern name year votes. The year is either "s" for sophomore or "j" for junior. Your program should output the candidate in each presidential race with the most votes, and how many votes they got. Specifically, if this file were named candidates.txt, your method could be called in the following way: Scanner input new Scanner (new File("candidates.txt")); classPresidents (input); The above call should produce the following output:…
- If wrong answer this time will downvote it Create a class with a static main that tests the ability to resolve and print a Path: • Create an instance of a FileSystem class. • Resolve an instance of a Path interface from a directory path and filename. • Print the constructed Path with System.out.println() method. 2. Create a class with a static main that tests the ability to resolve and print a Path: • Create an array of Path class. • Instantiate instances of Path with absolute and relative paths. • Print the constructed elements of the array of Path class with System.out.println() method. 3. Create a class to test serialisation class that implements serializable, it should implement the following: • A static void method that serialises an object. • A static void method that deserializes an object. • A static main method that tests the two by moving an object from one to the otherWe use Exception Handling for ?

When clicking the operators (+, -, *, /): the result will display at the bottom, and stored in history. When clicking C, clear the first, second number and the history. When clicking H, the history will display at the bottom. When the user click / and the second number is 0 throw an arithmetic exception.
