Write a C program that gets a source file name from a user. If the file does not exist, it will generate a proper error and exits.If the file exists, it also gets the name of two more files from the user, say destination1 and destination2. These files don’t need to exist as they are files that need to be written to. If the files cannot be opened for writing, a proper error will be generated. The program then reads the source file line by line. It will copy every line that has a digit in it to destination 2 and lines that have no digit in them to destination 1. Feel free to use ctype’s isdigit() function to identify digit characters. Example: If source file is:Hi My name is VeriaHello My name is John. How can I help you?I have a problem with my giga bit internet. The speed should be around 1000 but it’s just 200 Sure! I can help with that. Can I have your number in case we get disconnected? Sure! My number’s 647-123-1234 First file (destination 1) should be Hi My name is Veria Hello…
IN C++: Semaphores are used to mediate access to computer resources. Your task is to write a program that uses semaphores to simulate mediated access to three computer resources: 5 printers 6 plotters 4 scanners Your program shall: Declare and initialize the semaphores with the appropriate values. Create a routine that loops through a sequence 4 times. In each iteration the process forks a child process.The child process: uses a random number generator (1-3) to determine which resource it will request uses native semaphore function or one that you create to request the appropriate resource Print the process’ PID and the requested resource type Print the process’ PID and the success/failure of the request if the resource is available - sleep for a random time between 1-3 seconds and then release the resource using appropriate the semaphore function if the resource is not available – sleep for a random between 2-4 seconds and repeat the request (go to step ii). Terminate Sleeps…
In python, rite a recursive function, displayFiles, that expects a pathname as an argument. The path name can be either the name of a file or the name of a directory. If the pathname refers to a file, its filepath is displayed, followed by its contents, like so: File name: file_path Lorem ipsum dolor sit amet, consectetur adipiscing elit... Otherwise, if the pathname refers to a directory, the function is applied to each name in the directory, like so: Directory name: directory_path File name: file_path1 Lorem ipsum dolor sit amet... File name: file_path2 Lorem ipsum dolor sit amet... ... Test this function in a new program.
Walmart Canada debuted a new checkout system called "fast lane" that lets customers avoid cashiers and registers. Here's how it works: My Walmart users scan items with their phones as they shop. Once a user is finished shopping, they click "checkout" to receive a barcode. Next, the customer scans the order barcode at one of four scanning stations in the fast lane. This action charges the credit card the My Walmart user has on file. Finally, just before exiting the store, customers present their mobile receipts to a worker tending the fast lane. The system has debuted in a newly opened store in Toronto that Walmart says will serve as a prototype for future store renovations. Assume the new fast lane setup will replace 2 old cashier lanes that were staffed by a cashier and bagger on each lane. One worker mans all 4 scanning stations (answering questions, checking for un-scanned items, taking coupons, etc). Checkout on the new lanes takes 2 minutes (customers bag their own orders) while…

use c code to Write a C program that gets a source file name from a user. If the file does not exist, it will generate a proper error and exits.If the file exists, it also gets the name of two files from the user, say destination1 and destination2. These files don’t need to exist as they are files that need to be written to. The program then reads the source file line by line. If the line starts with an uppercase and ends with a lower case, it copies that line to dest1 (first destination file) If the line starts with a lowercase and ends with a dot (‘.’), it copies that line to dest2 (second destination file) If neither of the above hold, the program discards that line (doesn’t copy it anywhere) The program then displays a report mentioning how many lines were copied into each destination file. Don’t forget to close all the files. Example: Assume that the source file is (<NL> = new line, <EOF> end of file): Souce: “myfile.txt” This is my first…
The Payroll Department keeps a list of employee information for each pay period in a text file. The format of each line of the file is the following: <last name> <hours worked> <hourly wage> Write a program that inputs a filename from the user and prints to the terminal a report of the wages paid to the employees for the given period. The report should be in tabular format with the appropriate header. Each line should contain: An employee’s name The hours worked The wages paid for that period. An example of the program input and output is shown below: Enter the file name: data.txt Name Hours Total Pay Lambert 34 357.00 Osborne 22 137.50 Giacometti 5 503.50

Write a program in Python that serves as a password checker. The string password that Python should check for is, "wahtZ9t%". The program must limit the user to 3 password attempts. A loop controlled by the range function must be used to execute up to 3 times. If the user entered password matches the target then the computer should output a success message that includes the number of tries it took to get it right. Then the loop must exit. Otherwise display a failure message, including attempts left and return to top of loop. If the user fails all 3 attempts output a message that the users password has been revoked. Process: • Declare and set values for variables needed throughout the code OA string containing the "target" password: "wahtZ9t%" o A limit for attempts at entering the password: 3 o A Boolean value to show if the user succeeded in entering the password (or not) • Create an iterative structure to execute up to 3 times: . o Prompt the user for a password o If the entered…
