Solved in 2 steps
- (Data processing) Write a C++ program that reads the file created in Exercise 4, permits the user to change the hourly wage or years for any employee, and creates a new updated file.C# please Write a program that will create file with at least 10 lines. Each line of your file should have information delimited by some delimiter (I.e., commas, spaces, slashes, symbols, etc.). After your file has been created with the proper amount of data, you should read your file line by line and display without the delimiters in the same program after closing your writer. Additionally, the information stored into your file should be data that is gathered from a separate class. Your program should save your file in a specific directory. To promote flexibility, your program should check to see if the chosen directory exists prior creating it, and if it does not exist, your program should create it for you. Additionally, you should allow the user to enter the names of the directory and file instead of hard-coding it into your program.Password validation Write a program password.py that reads a file containing multiple passwords and checks the validity of the passwords. The file format is identical to one of the sample passwords.txt provided below. Your program must contain the following functions: Function name Function description Function input(s) Function return value(s) validate() This function takes a password string as input and returns a boolean that determines if the password is valid or invalid. The requirements for a valid password are: The password must be at least 9 characters long and at most 18 characters long (included). The password must end with a letter. The ending letter must be uppercase. The password must contain `62` The password must not start with `@` The password must contain at least 4 digits Password string Boolean main() This function prompts for a file of passwords. Next, it opens the file. Next, it checks for the validity of every password in…
- In C++ code: Design and write a C++ class that reads text, binary and csv files. The class functions: Size: Returns the file sizeName: Returns the file nameRaw: Returns the unparsed raw dataParse: A external function to Parse the data. The function accepts the raw data and returns the data parsed by the function. This type of function is called a "Call-Back Function". A Call-Back is necessary for each file as each file requires different regular expressions to parse. Call-back.cpp #include <string>#include <functional>#include <iostream>#include <vector>using namespace std; string ToLower(string s){ string temp; for (char c : s) temp.push_back(tolower(c)); temp.push_back(NULL); return temp;} string ToUpper(string s){ string temp; for (char c : s) temp.push_back(toupper(c)); temp.push_back(NULL); return temp;} struct Append{ string operator()(string a, string b) // function object { return a…Challenge Activity 1: Word List File Writer and Reader (a)Write a console and GUI program using *PYTHON* that asks the user how many words they would like to write to a file, and then asks the user to enter that many words, one at a time. The words should be written to a file. (b) Write another program that reads the words from the file and displays the following data: The number of words in the file. The longest word in the file. The average length of all of the words in the file.EmpFromFile Implement a function readEmpFromFile that takes a FILE * as the only argument and returns a pointer to a struct employee. This function should read the information from the file (reversing what writeEmpToFile does), create a new employee and fill in the data. If the FILE has no more info (is at end of file), this function should return NULL. This function must also ensure any employee actually created (not the NULL) is added to the array (as is done in createEmployee). Change main to load employees from a file using a command called LOAD which is given to the program using (using your readEmpFromFile function you just wrote). void main(void) { int end = 1; char * command; char buff[256]; char * findEmp; char findBuff[256]; char * sortType; char sortBuff[256]; char hire[] = "HIRE"; char list[] = "LIST"; char quit[] = "QUIT"; char find[] = "FIND"; char fire[] = "FIRE"; char _sort[] = "SORT"; char salary[] =…
- C++A new video store in your neighborhood is about to open. However, it does not have a program to keep track of its videos and customers. The store managers want someone to write a program for their system so that the video store can operate. The program will require you to design 2 ADTs as described below: [1] VIDEO ADT Data Operations Video_ID (preferably int, auto-generated) Movie Title Genre Production Number of Copies Movie Image Filename [1] Insert a new video [2] Rent a video; that is, check out a video [3] Return a video, or check in, a video [4] Show the details of a particular video [5] Display all videos in the store [6] Check whether a particular video is in the store [2] CUSTOMER PARENT ADT Data Operations Customer_ID (preferably int, auto-generated) Name Address [1] Add Customer [2] Show the customer details [3] Print list of all customers [3] CUSTOMER-RENT CHILD ADT Customer_ID ( Video_ID (of all rented videos of a…C# Write, compile, and test a console application named FileComparison that compares two files. First, use a text editor such as Notepad to save your favorite movie quote. Next, copy the file contents, and paste them into a word-processing program such as Word. Then, write the file-comparison application that displays the sizes of the two files as well as the ratio of their sizes to each other. To discover a file's size, you can create a System.IO.FileInfo object using statements such as the following, where FILE_NAME is a string that contains the name of the file, and size has been declared as an integer: FileInfo fileInfo = new FileInfo(FILE_NAME) ;Size = fileInfo.Length;C Standard Library The C library stdio.h provides several key input/output functions. For questions 1-13, please match the names to the best descriptions of their functions. fclose() feof() fopen() c. Reads formatted input from a file fprintf() d. Reads formatted input from stdin printf() e. Reads a line from a file and stores it into a string sprintf() f. Reads a line from stdin and stores it into a string fscanf() g. Writes a string (plus newline character) to stdout scanf() h. Writes a string (plus newline character) to a file sscanf() i. Test the end-of-file indicator for a file fgets() j. Reads formatted input from a string fputs() k. Sends formatted output to a string gets() l. Close a file puts() m. Opens a filename using the given mode a. Sends formatted output to a file b.

- program5_1.pyWrite a program that operates like a cashier terminal in a grocery store. It begins by prompting for the number of different items being purchased and then starts a loop. In the loop, the program should prompt for the item description, price and quantity of each item being purchased. These three values should be passed as arguments to a custom function that is defined in a separate module file. The imported function should print the subtotal for the item and return it to main. The total should be printed in main after the loop ends.readEmpFromFile Implement a function readEmpFromFile that takes a FILE * as the only argument and returns a pointer to a struct employee. This function should read the information from the file (reversing what writeEmpToFile does), create a new employee and fill in the data. If the FILE has no more info (is at end of file), this function should return NULL. This function must also ensure any employee actually created (not the NULL) is added to the array (as is done in createEmployee). Change main to load employees from a file using a command called LOAD which is given to the program using (using your readEmpFromFile function you just wrote). void main(void) { int end = 1; char * command; char buff[256]; char * findEmp; char findBuff[256]; char * sortType; char sortBuff[256]; char hire[] = "HIRE"; char list[] = "LIST"; char quit[] = "QUIT"; char find[] = "FIND"; char fire[] = "FIRE"; char _sort[] = "SORT"; char salary[] =…Help with c program using FILE HANDLING (fopen, fputs, fgets, etc.) You can also test the program with the following input.txt file A1, A2 20294 Lorenzana Dr Woodland Hills, CA 91364 B1, B2 19831 Henshaw St Culver City, CA 94023 C1, C2 5142 Dumont Pl Azusa, CA 91112 D1, D2 20636 De Forest St Woodland Hills, CA 91364 A1, A2 20294 Lorenzana Dr Woodland Hills, CA 91364 E1, E2 4851 Poe Ave Woodland Hills, CA 91364 F1, F2 20225 Lorenzana Dr Los Angeles, CA 91111 G1, G2 20253 Lorenzana Dr Los Angeles, CA 90005 H1, H2 5241 Del Moreno Dr Los Angeles, CA 91110 I1, I2 5332 Felice Pl Stevenson Ranch, CA 94135 J1, J2 5135 Quakertown Ave Thousand Oaks, CA 91362 K1, K2 720 Eucalyptus Ave 105 Inglewood, CA 89030 L1, L2 5021 Dumont Pl Woodland Hills, CA 91364 M1, M2 4819 Quedo Pl Westlake Village, CA 91362 I1, I2 5332 Felice Pl Stevenson Ranch, CA 94135 I1, I2 5332 Felice Pl Stevenson Ranch, CA 94135 N1, N2 20044 Wells Dr Beverly Hills, CA 90210 O1, O2 7659 Mckinley Ave Los Angeles, CA 90001…
