IN C++ VISUAL STUDIO
Create two classes one to read data from file, and the other to write data into a file. The data can be about employees having information about employee name, id and designation. You must create a class for employee. There is a total of 3 classes in your program. In the second class, which is about file writing, you have to write data about 10 employees in file. You can get data from user. In reading class, you have to read information about a specific employee whose id is given by user. Finally write a function to show data about employees whose designation is “manager”.
Here are the two programs which you may choose from to do this program:
1. Using Files - Student Line Up
Modify the Student Line Up program described in Programming Challenge 14 which
states:
"A teacher has asked all of her students to line up according to their first name. For
example, in one class Amy will at the front of the line, and Yolanda will be at the end.
Write a program that prompts the user to enter the number of students in the class, then
loops to read that many names. Once all of the names have been read, it reports which
student would be at the front of the line and which one would be at the end of the line.
You may assume that no two students have the same name.
You are now to do this program reading names from a file. Names should be read in
until there is no more data to be read. I am providing for you a file named LineUp.txt
for you to use in writing this program.
I suggest that you write it first without the file and then modify to add the file.
2. The manager of a basketball stadium wants you to write a program that
calculates the total ticket sales after each game. There are four types of
tickets – box, sideline, premium, and general admission. After each game,
data is stored in a file in the following forms:
ticketPrice
numberOfTicketsSold
Sample data are shown below:
250
5750
100
28000
50
35750
25
18750
The first line indicates that the box ticket price is 250 pesos and that 5750
Tickets were sold at that price. Output the number of the tickets sold and the
total sale amount. Format your output with two decimal places.

- A MyPetStore sells many pets and their accessories. As new pets are added to the MyPetStore, theirinformation is entered into a flat text file. Each month, the manager requests a listing of all pets sorted bytheir price. You must write a program to produce a report of MyPetStore and their types sorted by their pricesfrom the data in the flat text file.

In addition to the above, the user(s) should be asked if they want to modify their car’s specs. Such as the type of race car (Ford, Chevy, Dodge, etc.), the car number, name of driver, and the color. The user should be able to make changes to their vehicle between each race. The modifications are to be saved to a file. With each key press a random number between 0 and 10 is generated to represent the cars next distance to travel.arrow_forward
- Finish this program from the code posted below! Note: There should be two files Main.py and Contact.py You will implement the edit_contact function. In the function, do the following: Ask the user to enter the name of the contact they want to edit. If the contact exists, in a loop, give them the following choices Remove one of the phone numbers from that Contact. Add a phone number to that Contact. Change that Contact's email address. Change that Contact's name (if they do this, you will have to remove the key/value pair from the dictionary and re-add it, since the key is the contact’s name. Use the dictionary's pop method for this!) Stop editing the Contact Once the user is finished making changes to the Contact, the function should return.

The function can be called as follows: createFile(filename, n) Main function, in which the user inputs the file name and the number of students, then the main calls function createFile.
