Problem Definition
You are provided with a text file (employees.txt) containing a number of text lines. Each line contains a record of one
employee. Each record has three attributes:
Title: string, Prof. (Professor) or Dr. (Doctor).
First and Last names: string.
Salary: float number.
The attributes are separated by the character (',). Figure 1.a, 1.b, and 1.c show a sample of employees.txt files.

- C++ code The Curl Up and Dye Beauty Salon maintains a master file that contains a record for each of its clients. Fields in the master file include the client’s ID number, first name, last name, and total amount spent this year. Every week, a transaction file is produced. It contains a customer’s ID number, the service received (for example, Manicure), and the price paid. Each file is sorted in ID number order. a. Design the logic for a program that matches the master and transaction file records and updates the total paid for each client by adding the current week’s price paid to the cumulative total. Not all clients purchase services each week. The output is the updated master file and an error report that lists any transaction records for which no master record exists. // Pseudocode PLD Chapter 7 #6a pg. 301// Start// Declarations// InputFile masterFile;// InputFile transactionFile;// OutputFile newMasterFile;// num mClientNumber, mtotalClientCost, tClientNumber, titemClientCost//…arrow_forwardProblem Definition You are provided with a text file (employees.txt) containing a number of text lines.

- Print Person Information from file In this lab you are asked to complete the function : print_person_from_file(person_name, filename). This function should read in data from the file filename and print the information for person_name if it is found in the file.
