5. Charge Account Validation
If you have downloaded the source code from the Computer Science Portal you will find
a file named charge_accounts.txt in the Chapter 07 folder. This file has a list of a com-
pany's valid charge account numbers. Each account number is a seven-digit number, such
as 5658845.
Programming Exercises 403
program
Write a program that reads the contents of the file into a list. The program should then
ask the user to enter a charge account number. The program should determine whether
the number is valid by searching for it in the list. If the number is in the list, the
should display a message indicating the number is valid. If the number is not in the list, the
program should display a message indicating the number is invalid.

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.…

- Program Description:in C language The project is a student management system which maintains student records in a simple text file. Your task is to write a program to save a list of students records in a FILE and then perform several operations on this FILE. Your program will ask user to choose the option from a menu. 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. If the student is found it will print her/his record to the output. If the student is not found it will print “There is no record of this student in this system” 3.

You can assume that the input file only one number per line. You can assume the user always enter a file that exists. The median is the value in the middle of a sorted list. To sort a list, use list.sort() function. It’s computed as below. For a list of odd length, the middle number is just the length divide by 2. For the list, [1,2,3], the median is 2 since 2 is in the middle of the list. The middle index is 3//2, which is 1. Remember that // is the integer division operator. When the length of the list is even, there are two middle numbers. The median is the average of the two middle numbers. For example, [1,2,3,4], the median is (2+3)/2 = 2.5. The two middle indexes for this example are (4//2)-1 = 1 and (4//2) = 2.

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. Example Output: Enter basic salary : 200 Enter basic salary : 300 Enter basic salary : 450 Enter basic salary : 600 Enter basic salary : 750 Enter incentive rate : 0.50 Basic salary [200,300,450,600,750] Net Salary [100,150,225,300,375]arrow_forwardC++ You should create a loop which will ask user if they want to insert, delete, display and exit.
