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.

- (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. Create the file by entering five customer records, with each record consisting of an integer account number (starting with account number 1000), a first name (maximum of 10 characters), a last name (maximum of 15 characters), and a double-precision number for the account balance. After the file is created, write a C++ program that requests a user-input account number and displays the corresponding name and account balance from the file.arrow_forwardC programming language Criteria graded: Declare file pointers Open file Read from file Write to file Close file Instructions: Write a segment of code that opens a file called “numbers.txt” for reading. This file is known to have 10 numbers in it. Read in each number and print a ‘*’ to the screen if the number is even. If the number is odd, do nothing. Conclude by closing this file.arrow_forward
- Programming language: C/C++, Java, Python, or any other advanced programming languages Project Description: the file “IntegerArray.txt” included in this project folder contains all the 100,000 integers between 1 and 100,000 (inclusive) in some order, with no integer repeated. Your task is to compute the number of inversions in the file given, where the i-th row of the file indicates the i-th entry of an array. Because of the large size of this array, you should implement a divide-and-conquer algorithm.arrow_forwardINSTRUCTION: C++ Language Create a function that writes to a file named Inventy.txt the information of 8 items. Ask the user for the item's name, the item's quantity in storage, and the item's price and write it to the file. Create a function that reads the file and items' quantity and price to two different arrays. Create a function that computes the subtotal of each item. Implement all functions inside the main program and the computed value should be displayed with the item's name.arrow_forwardSubmission: Combine the code files for Q1 and Q2 as a zip file and submit in Moodle Question 1: Write a Program that to enter Student Name, Grade and print it to the screen with below requirements . . . . Asks the users how many student grades they want to enter. Based on that number the program should setup a loop to ask the user to enter student name and the student grade. Save this information using 2 arrays At the end the program must show the student names and grades with 1 student on each line on the screen Program should use Arrays and loops to achieve the task.arrow_forward
- Multi Dimensional Activity Client Requirement: The customer wants a program that will ask the user to enter 2 numbers. these numbers will then be stored in the first two columns. the cycle will repeat until the 5 by 2 array will be completed. then the values will be prompted for checking.arrow_forwardSearching - a user should be able to search by ID or by item name create only one menu item for searching a user should be able to enter the name of the item using any case, (for example, sTRolleR) you may wish to store items in all lower/upper case to expedite the search write one search function that can search by ID and name and goes through the array of structs/objects only once show the entire record if found or an appropriate message if not Sorting - sort by any field write one function to sort by any field using a parallel array of pointers use Bubble Sort is not the most effective but the easiest to modify. do not copy and paste sort code five times into the same function. sorting using pointers is faster because you have to swap pointers only, which are normally stored in 4 bytes each; it also allows you to preserve the original order of the items If you choose to have a submenu, a submenu must have an option to go back to the previous menu or main menu if a user got…arrow_forward1- Arrays can be created to store values of multiple data types at one place. True False 2- To copy the contents of one array to another you must copy the individual array elements. True Falsearrow_forward
- Number Analysis Program (FYI: Pseudocode not any specific programming language.) Write a pseudocode algorithm that asks the user to enter a series of 20 numbers. The program should store the numbers in an array and 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 arrayarrow_forwardC++arrays, c-strings, functions with arrays as parameters 1. Create a file that contains 20 integers or download the attached file twenty_integers.txt Create a program that: 2. Declares a c-style string array that will store a filename. 3. Prompts the user to enter a filename. Store the file name declared in the c-string. 4. Opens the file. Write code to check the file state. If the file fails to open, display a message and exit the program. 5. Declare an array that holds 20 integers. Read the 20 integers from the fileinto the array.6. Write a function that accepts the filled array as a parameter and determines the MAXIMUM value in the array.Return the maximum value from the function (the function will be of type int).7. Print ALL the array values AND print the maximum value in the array using a range-based for loop. Use informational messages.Ensure the output is readable.arrow_forwardAn array is a group of random memory locations that all have different data type Select one: True O Falsearrow_forward
