Data structure (C++) "Write the code in C++ and provide a link for CPP File please" Problem: Create an employee Record Management system using linked listthat can perform the following operations:• Insert employee record• Delete employee record• Update employee record• Show employee• Search employee• Update salary The employee record should contain the following items• Name of Employee• ID of Employee• First day of work• Phone number of the employee• Address of the employee• Work hours• Salary Approach:With the basic knowledge of operations on Linked Lists like insertion, deletion of elementsin the Linked list, the employee record management system can be created. Below are thefunctionalities explained that are to be implemented:Check Record: It is a utility function of creating a record it checks before insertionthat the Record Already Exist or not.

C++ Progrmaing Instructions Redo Programming Exercise 6 of Chapter 8 using dynamic arrays. The instructions have been posted for your convenience. The history teacher at your school needs help in grading a True/False test. The students’ IDs and test answers are stored in a file. The first entry in the file contains answers to the test in the form: TFFTFFTTTTFFTFTFTFTT Every other entry in the file is the student ID, followed by a blank, followed by the student’s responses. For example, the entry: ABC54301 TFTFTFTT TFTFTFFTTFT indicates that the student ID is ABC54301 and the answer to question 1 is True, the answer to question 2 is False, and so on. This student did not answer question 9 (note the empty space). The exam has 20 questions, and the class has more than 150 students. Each correct answer is awarded two points, each wrong answer gets one point deducted, and no answer gets zero points. Write a program that processes the test data. The output should be the student’s ID,…

C++ arrays task The scientist monitors the movement of a particle suspended on the surface of the water and records its coordinates every n seconds. make a program that calculates the minimum, average, and maximum velocities of the particle and the distance traveled by the particle. The first line of the original data file contains the number of particle coordinates m (1 <m <100) and the coordinate capture interval in n (n> 0) seconds. The following lines show the particle coordinates xi and yi (1 <i <m) in millimeters (xi and yi are real numbers). Record the minimum, average, and maximum velocities of the particle and the distance traveled by the particle in the result file.

Array Basics in C++ In this lab, you complete a partially prewritten C++ program that uses an array. The program prompts the user to interactively enter eight batting averages, which the program stores in an array. The program should then find the minimum and maximum batting average stored in the array as well as the average of the eight batting averages. The data file provided for this lab includes the input statement and some variable declarations. Comments are included in the file to help you write the remainder of the program. Instructions Ensure the source code file named BattingAverage.cpp is open in the code editor. Write the C++ statements as indicated by the comments. Execute the program by clicking the Run button. Enter the following batting averages: .299, .157, .242, .203, .198, .333, .270, .190. The minimum batting average should be .157, and the maximum batting average should be .333. The average should be .2365. USE GIVEN CODE #include <iostream> #include…

File Handling with Array: C++ Language: Write a c++ program to read the data from the file into array and do calculation. Note: Take a general word problem and write syntax which will use in all problems related to file handling with array.
(Data processing) A bank’s customer records are to be stored in a file and read into a set of arrays so that a customer’s record can be accessed randomly by account number. Create the file by entering five customer records, with each record consisting of an integer account number (starting with account number 1000), a first name (maximum of 10 characters), a last name (maximum of 15 characters), and a double-precision number for the account balance. After the file is created, write a C++ program that requests a user-input account number and displays the corresponding name and account balance from the file.
