Changing directories You will need to implement change_directory so that it changes the current working directory of tide. All other functions should now operate on the new working directory. Supplied directories can be both relative and absolute. Additionally, your implementation should expand into the user's home directory, using the HOME environment variable. Once you have this function working correctly, your tide implementation should match the following behaviour: $ 1521 tide-examples $ cd examples $ 1521 tide Welcome to tide! To see what commands are available, type help. tide> cd a

Utilize looping to make your Python script for Functionality 2 You should allow users to enter information for five employees at the same time, where the first employee information entry is saved in index [0] and the second entry is saved in index [1], and so on. You want to make sure to enforce the user to enter the following employee information: employeeName, employeeSSN, employeePhone, employeeEmail, employeeSalary. After the user finishes entering the last employee information, they should get a message to allow them to print specific employee information from the saved list. The user can enter values between 1 and 5, where 1 will return the employee information saved in the list index [0], 2 will return the employee information saved in the list index [1] and so on.]to run constantly. while having it run constantly Add Employee – this functionality will allow users to add new employee to the system.

A client with a completed main function is provided. The main function should not be modified. You must update the client by creating and implementing the various functions described below. readFile – Loads the parameter array with Billionaire objects. The data for each Billionaire is read from the given data file which is in CSV format (comma delimited - 1 line per record with fields separated by a comma.) The function should read each line from the file, pass the line read to the Billionaire class constructor and store the resulting object in the parameter array. The second parameter represents the maximum number of Billionaire objects that can be stored. displayAll - Displays a list of the Billionaires stored in the array. getRange – Determines the smallest wealth value and the largest wealth value within the array. These values are returned to the caller via reference parameters. getWealthiest – Returns the Billionaire within the array with the greatest wealth. getUS –…
You should not make any changes to DPQueue.h. ■ You should not remove any functions from DPQueue.cpp, and you need to: ● Fill in the implementation of all the "stub" functions in the file (those with output statements containing the message "??? not implemented yet"), and ● Provide any additional documentation where appropriate. The file SuccessfulAutoTest.txt shows how the output for a test with complete success should look like. ► Referring to it should give you a purview of the number/kind of tests involved. #endifusing namespace std; namespace CS3358_FA2022_A7{ // CONSTRUCTORS AND DESTRUCTOR p_queue::p_queue(size_type initial_capacity) { cerr << "p_queue() not implemented yet" << endl; } p_queue::p_queue(const p_queue& src) { cerr << "p_queue(const p_queue&) not implemented yet" << endl; } p_queue::~p_queue() { cerr << "~p_queue() not implemented yet" <<…
Create an Azure Functions project, containing a single function. The purpose of the function is to calculate the status of a module: fail, pass condoned, pass or pass with distinction. The requirements of the function are as follows:  The function must make use of an HTTP trigger.  The name of the function should be CalculateModuleStatus.  The function should accept a single MarkEntry object as input, from either a get or a post operation. Here is the definition of the MarkEntry class that you must use: public class MarkEntry{public string StudentNumber { get; set; }public string Name { get; set; }public int Mark { get; set; }public string Module { get; set; }} The function should determine the status as follows: o 0 to 48: return “Fail” o 49: return “Pass (Condoned)” o 50 to 74: return “Pass” o 75 to 100: return “Pass with Distinction”  The function should return an error if no MarkEntry is provided.
The default library method int fseek(FILE *fp, long offset, int origin) is similar to Iseek except that the return value is an int status rather than a location, and fp is a file reference rather than a file descriptor. Compose fseek. Ensure that the caching used for the other library functions and your fseek are correctly coordinated.
Modify your code so that before the game begins, the player is asked whether they wish to enter their guesses manually, or to automatically guess based on pre-supplied guesses in a file. If the first option is chosen, then the game should progress in the same fashion as in the tasks above. If the second option is chosen, then the following actions should be taken: Firstly, the player should be asked to enter a filename. If the player enters an invalid filename, they should be re-prompted until they enter the name of a file that actually exists. This file should then be read and interpreted as a text file, where each line contains a separate guess. For example, a sample file input.txt may contain the following text: 1234 4321 5830 8437 1489 3271 2530 You may assume that each line of the file contains a valid guess. Once the file has been read, then the game should proceed as normal. However, when the player would be prompted to enter a guess, the next guess in the list of pre-supplied…
please write c++. thanks in advance. ATTENTION : Your project Name shall be like 200201543.dev and you must upload to OTUZEM together with related .cpp files and class interface file. Ostim Technique University Proffessor is teaching two courses, namely CENG103 and CENG104. For each course registration quota is maximum 25 students. At the end of the semester, both courses final grades are written in the same sequential access file, namely CE103-104.txt. The format of sequential file is given below. The program will read the CE103-104.txt file and for each course, the average of the final exam grades will be calculated, highest score and lowest score will be found. Your program will define related objects for each course. These operations will be performed by the related course objects' member functions. The class interface file and member functions implementations of the class will be located in separate files. Hint: Use the sample program files given in the class studies. Sample…
This C++ menu-driven program on LIBRARY MANAGEMENT SYSTEM has book and student class with data members like a book no, book name, author name. Books records are stored in a binary file. A student can issue a book and deposit it within 15 days. The student is allowed to issue only one book. Student Records are stored in the binary file. The administrator can add, modify or delete records.In this project, do not use graphics to keep the program simple.
Write comparators for the typeFile to order by increasing/decreasing order of file size, ascending/descending orderof file name, and ascending/descending order of last modification date. Use thesecomparators in a program LS that takes a command-line argument and lists the filesin the current directory according to a specified order, e.g., "-t" to sort by timestamp.Support multiple flags to break ties. Be sure to use a stable sort
Implement all the functions from the Question 2 and make a login and sign up module, all thedata will be stored in the files and as well as in the linked list, Program will have two modules1. login2. sign upSign Up:In this module the program will ask the user to enter username, password, address, city, phonenumber, gender and will store the data in the linked list. If the username already exists in thelinked list it will ask the user to change the username, all the data will also be stored in the textfile.Login: In this module the user will enter its username and password, the program will check if the dataexists in the linked list, if yes then show “Welcome to home screen”, if not then ask the user toenter the username and password again.Work Flow:1. The program will start and all the data from the files will be loaded in the linked list.2. The login and sign up screen will pop up3. Apply proper checks, if the file exists or not (Hint: you can use try catch to handle theexceptions)…

C++ PLEASE!! Working on a project that is about word count with MapReduce, need a file manager class to take care of reading all txt file from a directory with giving path. The file manager class need to open the directory with the giving path which the user will input, then open the path and open all the txt files in that directory and break the text into single line and pass it to another class to do mapping. Please help with the file manager class!! Thank you!!
