- (Data processing) Write a C++ program that reads the file created in Exercise 4, permits the user to change the hourly wage or years for any employee, and creates a new updated file.Write a program in C++ to do the following: 2. Create an array to hold up to 20 integers. 3. Create a data file or download attached text file (twenty_numbers.txt) thatcontains UP TO 20 integers.4. Request the input and output file names from the user. Open the filesbeing sure to check the file state.5. Request from the user HOW MANY numbers to read from the data file,up to twenty. Request the number until the user enters 20 or less, but not lessthan 0. The user enters the number of integers to read. The integers are storedin the file and are to be read from the file.6. Write a function that reads from the opened data file: the numberof integers the user wants to read, and store the numbers inthe array. For example, if the user wants to read 13 numbers,read 13 of the 20 that may be in the file.7. Write a function that writes to the opened output file AND THECONSOLE, the numbers stored in the array.8. NO GLOBAL variables are to be used. The input and output file variablesmust be passed…1. Write a program in C/C++ that reads a table of data from an input file and displays the data. The program then prompts the user to see the data in specific order. The output of your program should display the sorted data (descending order) according to the user selection. Your program should display the prompt repeatedly until the user wants to exit. See the test run. The input file contains four data fields: Country, Total cases, New cases, and Total deaths. The number of rows (data) can vary between 5 to 100. You must use Quick sort in your implementation. Example test run: Country Total Cases New Cases Total Deaths USA 48072665 70590 784775 India 34447536 10560 463655 Brazil 21960766 2799 611384 UK…
- Transcribed Image Text Problem 3) Create a text file that contains the following information: John Doe 2005 124.80 36 Note that the fist line represents the name of the client, the second line represents the year in which the client started an account with this insurance company. The third line represent the monthly payment for the insurance. The fourth line represents the number of months left in the insurance policy. Write a C++ program that will read this file and will display the client's name, the number of years for which this client has been with the company, and the remaining amount they have to pay6.20 Word count (c++) using (#include<fstream>) Write a program that prompts the user to input the name of a text file and then outputs the number of words in the file. You can consider a "word" to be any text that is surrounded by whitespace (for example, a space, carriage return, newline) or borders the beginning or end of the file.Input Notes: There are two input sources in this program: the text file and standard input. The standard input consists of a single word, the name of the text file to be read. DO NOT USE A STRING VARIABLE.Output Notes (Prompts and Labels): The filename provided in standard input is prompted for with "Enter a file name: " and displayed so that the filename entered is on the same line as the prompt.The output of the program is a single line of the form: "The file contains N words." where N is the number of words determined by the program.(a) Write a C function readNums() that takes a filename and an integer array, reads the integer numbers in the file and stores into the array, returns the number of numbers stored in the array. Assume that the file only contains integer numbers, and nothing else. Prototype: int readNums(char filename[], int arr[]); (b) Write a C function delWordN() that takes a string and an integer (n) as parameter, removes from the string the words that are n character long. A word is a group of consecutive alphanumeric characters; words are separated by non-alphanumeric characters. ps: please do not copy paste from chegg or anywhere else. write unique code
- Please help with C++, CANNOT use array or vector CAN ONLY USE BELOW #include<iostream> #include<fstream> #include<string> #include<iomanip> This program numbers the lines found in a text file. (text file name is story.txt) Write a program that reads text from a file and outputs each line to the screen and to another file preceded (preceding file name outputfile.txt) by a line number. Print the line number at the start of the line and right-adjusted in a field of three spaces. Follow the line number with a colon, then one space, then the text of the line. You should get a character at a time and write code to ignore leading blanks on each line. You may assume that the lines are short enough to fit within a line on the screen. Otherwise, allow default printer or screen output behavior if the line is too long (that is, wrap or truncate). A somewhat harder version determines the number of spaces needed in the field for the line numbers by counting lines before…#Problem #1 Searching for a Item in a File Write a program named SearchFile.py that reads in a list of items from a text file and looks for the presence of one that the user enters from the keyboard.

For ours, we will search for a bird name but the idea would be applicable for any searching in a file.6.20 Word count (c++) Write a program that prompts the user to input the name of a text file and then outputs the number of words in the file. You can consider a "word" to be any text that is surrounded by whitespace (for example, a space, carriage return, newline) or borders the beginning or end of the file.Input Notes: There are two input sources in this program: the text file and standard input.
