Program Specification
For this assignment you will write a program to help people record the events of their day by supplying prompts and then saving their responses along with the question and the date to a file.
Functional Requirements
This program must contain the following features:
Write a new entry - Show the user a random prompt (from a list that you create), and save their response, the prompt, and the date as an Entry.
Display the journal - Iterate through all entries in the journal and display them to the screen.
Save the journal to a file - Prompt the user for a filename and then save the current journal (the complete list of entries) to that file location.
Load the journal from a file - Prompt the user for a filename and then load the journal (a complete list of entries) from that file. This should replace any entries currently stored the journal.
Provide a menu that allows the user choose these options
Your list of prompts must contain at least five different prompts.…

Problem
Charge Account Validation
Create an application that reads the contents of the file into an array or a List . The application should then let the user enter a charge account number. The program should determine whether the number is valid by searching for it in the array or List that contains the valid charge account numbers. If the number is in the array or List , the program should display a message indicating the number is valid. If the number is not in the array or List , the program should display a message indicating the number is invalid.
For Visual Studio .Net 4.6.1
current solution on bartleby does not work as it does not actually use a list and does not properly retrieve the file
file is a text document with 18 7 digit numbers named ChargeAccounts.txt

The 3 major function in menu are: ADD STUDENT FIND STUDENT PRINT LIST Exit How it Works The menu is handled by do while and switch statement. Sample output The Methods to be implemented are as follows: 1. ADDSTUDENT This method will add a new student to the file. It takes 3 parameters ( student name, id, and GPA). Your program must ask the user to enter the details of new students: Name, ID and GPA 2. FINDSTUDENT This method will search for a student with his/her id in the file.

The user will then enter the incentive rate (Example. 0.15) The program should compute the net salary. The net salary is computed using the formula basic salary multiplied by incentive rate. Store the computed net salary in another list which will be named as net_salary. Display the values stored in the 2 lists.
