Given the variable names pathName contains a string describing a directory path, write a statement that will store the names of all files in a List structure named volume. DO NOT traverse the path/directory. You are only interested in the immediate path. You may assume that any neccesay statments already exist.

The Pinewood Derby involves racing Derby cards down multiple lanes and calculating the average time to determine the winner. Create a program that prompts the user to enter in the number of racers that are competing. For each racer that is competing, the user should be specified to enter in four race times and the program should display the average of those times. That data should be then saved to a file. The program should drop the racers slowest time and calculate the average of the remaining times to determine a winner. Note: The most common error I see is that people drop the fastest race time, not the slowest. The program does not need to report who won; the program just needs to display the adjusted average for each racer.

In C write a program that takes a file name and two strings as command line arguments, and writes the longer of the two strings to the file with the given name. If the given strings are the same length, write the first string given to the file. If the user does not provide the correct number of command line arguments, print an error message and exit the program with a non-zero exit code.

Word Puzzle GameIn this assignment is only for individual. You are going to decode the scrambled word into correct orderin this game. One round of play is as follows:1. Computer reads a text file named words.txt2. Computer randomly picks one word in the file and randomly scrambles characters in the wordmany times to hide the word3. Computer displays the scrambled word to user with indexes and gives the user options to1. Swap two letters in word based on index given2. Solve the puzzle directly3. Quit the game4. If a player chooses to swap letters, the computer reads two indexes and swaps the letters. Thegame resume to step 3 with the newly guessed word. If the resulted word after swapping is thesecret word, the game is over.5. If a user chooses to solve directly, computer prompts the user to enter the guessed word. If it’scorrect, the game is over, otherwise goes to step 3.6. After game is over, display how many times the player has tried to solve the puzzle.The following is sample...

In c++, ask the user for the name of a file to store the information. Open the file, and make sure it openedcorrectly.Allow the user to process multiple records. Prompt the user at the end of each cycle whether theywant to process any more records. (Hint: what kind of a loop will you use that processes at least oneitem?)Then, for each item in the inventory, your program should:1. Ask the user for the product name (use getline so you can input a multi-word product name)then read it in.2. Ask the user for the wholesale price per item and read that in.3. Ask the user for the quantity and read that in.4. Calculate the total price paid.5. Ask the user for the markup and read that in. ("Markup is usually expressed as a percentage,and is the amount the price is raised to give a retail price).6. Calculate the retail price.That forms a "record"; all the information we know about this item.Write the information to a file.The function should print to the file, on two lines, the information in the...

write the code to lookup, add and remove phoneentries from the phonebook text file . These are the code we use for the lookup, add and remove in the case statement.(Lookup)# Look someone up in the phone bookgrep 1ドル phonebook (add)echo "1ドル 2ドル" >> phonebooksort -o phonebook phonebook (Remove)grep -v "1ドル" phonebook > /tmp/phonebookmv /tmp/phonebook phonebook Write a complete Bash script which will accept up to three command-line arguments: the first one is either (lookup, add or remove), the second one is a name enclosed in single quotes and the third one (if doing an add) is a phone number enclosed in single quotes. Using a case statement to match on either lookup, add or remove, the script should then perform the requested operation. Again here, you should first check for null arguments before continuing with the rest of the script or requested operation. In addition, the person may not be in the phonebook for lookup or remove so, you need to account for this.

Using Java, create a personal directory that contains a data structure for first name, last name, email address and phone number. The data structure should be able to contain the information for an unlimited number of people (depending on system resources).• The program interface should consist of a menu that provides the user with ways to (at least):▪ Add: Get data from user and add the data to the structure.▪ View: which will view the current data in the directory ▪ Edit/Update: Edit existing data ▪ Remove: Delete an entry▪ Search: which prompts the user for search criteria (program should be smart enough to know how to tell what kind of data is being searched for. Try to make this as versatile as possible). Display the data if found. If not found add the new information to the data structure (you must provide the right input for this).The program should store the data in a file so that the program can be run whenever the user wants, even after closing.• Your program should:▪ Contain...

>> classicVinyls.cpp For the following program, you will use the text file called "vinyls.txt" attached to this assignment. The file stores information about a collection of classic vinyls. The records in the file are like the ones on the following sample: Led_Zeppelin Led_Zeppelin 1969 1000.00 The_Prettiest_Star David_Bowie 1973 2000.00 Speedway Elvis_Presley 1968 5000.00 Spirit_in_the_Night Bruce_Springsteen 1973 5000.00 ... Write a declaration for a structure named vinylRec that is to be used to store the records for the classic collection system. The fields in the record should include a title (string), an artist (string), the yearReleased (int), and an estimatedPrice(double). Create the following...

Python S3 Get File In the Python file, write a program to get all the files from a public S3 bucket named coderbytechallengesandbox. In there there might be multiple files, but your program should find the file with the prefix and cb - then output the full name of the file. You should use the boto3 module to solve this challenge. You do not need any access keys to access the bucket because it is public. This post might help you with how to access the bucket. Example Output ob name.txt Browse Resources Search for any help or documentation you might need for this problem. For exampler array indexing, Ruby hash tables, etc.

Case Problems - 1- In Chapter 8, you modified the EventDemo program for Carly’s Catering to accept and display data for an array of three Event objects. Now, modify the program to use an array of eight Event objects. Prompt the user to choose an option to sort Events in ascending order by event number, number of guests, or event type. Display the sorted list, and continue to prompt the user for sorting options until the user enters a sentinel value. Save the file as EventDemo.java.

in c# i need to Write the program named DirectoryInformation that allows a user to continually enter directory names until the user types end. If the directory name exists, display a list of the files in it; otherwise, display the following message, Directory foo does not exist, to indicate the directory does not exist (foo would be the name of the directory to be checked) . Create as many test directories and files as necessary to test your program. An example of the program is shown below: Enter a directory >> lorem lorem contains the following files lorem/ipsum.txt Enter another directory or type end to quit >> foo Directory foo does not exist

Please help with my C++Specifications • For the view and delete commands, display an error message if the user enters an invalid contact number. • Define a structure to store the data for each contact. • When you start the program, it should read the contacts from the tab-delimited text file and store them in a vector of contact objects. •When reading data from the text file, you can read all text up to the next tab by adding a tab character ('\t') as the third argument of the getline() function. •When you add or delete a contact, the change should be saved to the text file immediately. That way, no changes are lost, even if the program crashes later
