Number Analysis
Write a program that asks the user for a file name. Assume the file contains a series of numbers, each written on a separate line. The program should read the contents of the file into an array then display the following data:
• The lowest number in the array
• The highest number in the array
• The total of the numbers in the array
• The average of the numbers in the array
If you have downloaded this book’s source code, you will find a file named numbers, txt in the Chapter 07 folder. You can use the file to test the program.

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
Use C++
This program will read the contents of a file into an array and calculate various values based on the contents of the file.
The program will make use of a two dimensional array that has 30 rows and 5 columns.
You will be reading in the contents from a file. You will need to read the file name from cin. You will prompt for the file name with the prompt:
Enter input file name
The file will consist of up to 30 sets of 5 values. The values will all be double floating point values.
readFile function
One function you will be required to have is called readFile. This function will read the input file. Each read will read in 5 columns of information into the next available row in the two dimensional array. The first 5 values are read into row 0, the next 5 values will be read into row 1, and so on up to 30 rows of input. You will need to keep track of how many rows of input you have read in. This could be anywhere from 0 to 30. If there are more than 30 rows of input you should only…
The program is in JavaScript and must use const readline = require('readline');
1. Create a file named dedup.js. Write a program that removes duplicates from an array. The program should be able to read an unspecified number of numbers input by the user. The user should enter a negative number when they are done entering scores. The program should remove all duplicates from the array and then iterate over the new array and display it.
2. Create a file named dedeup_2.js. Modify your dedup program and prompt the user to enter a number n. Remove all elements from the array that occur more than n times.

- (File creation) Write a C++ program that creates an array containing the integer numbers 60, 40, 80, 90, 120, 150, 130, 160, 170, and 200. Your program should then write the data in the array to a text file. (Alternatively, you can create the file with a text editor.)arrow_forward(Statistics) Write a program that includes two functions named calcavg() and variance(). The calcavg() function should calculate and return the average of values stored in an array named testvals. The array should be declared in main() and include the values 89, 95, 72, 83, 99, 54, 86, 75, 92, 73, 79, 75, 82, and 73. The variance() function should calculate and return the variance of the data. The variance is obtained by subtracting the average from each value in testvals, squaring the values obtained, adding them, and dividing by the number of elements in testvals. The values returned from calcavg() and variance() should be displayed by using cout statements in main().arrow_forward(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.

- Using C# in Microsoft Visual Studio create an application that grades the written portion of the driver’s license exam. The exam has 20 multiple-choice questions. (The correct answers are provided in the screenshot.) the program should store these correct answers in an array. The program should read the student’s answers for each of the 20 questions from a text file and store the answers in another array. (Create your own text file to test the application.) After the student’s answers have been read from the file, the program should display a message indicating whether the student passed or failed the exam. (A student must correctly answer 15 of the 20 questions to pass the exam.)
