Data File: Example #1AAAAABBBBBCCCCCDDDDDAAEBCBAFBBCDCECDADDEFEEFFFExample #2AAATAABTBBBBCCCCTCDDTDDDAASAABBSBBCCSCCDSDDDEEEAEEFBFFFDDF Write a program that will give the user a brief introduction, then allow the user to type in the name of the file to be analyzed, the name of the data file to generate, and then process the data to match the output that is shown below. This DNA test measures the various parts of the sequence and assigns them a letter. While the letters could be anything from A to Z, the only letters that matter for this test are the letters {A,B,C,D} all other letters can be ignored completely. A sample will be tested, given a length of time and then tested again. Each time the scientist will generate a line of data. Here is one Example: Example #1 AAAAABBBBBCCCCCDDDDD AAEBCBAFBBCDCECDADDEFEEFFF At first glance the sample looks significantly different after the second test. But if you look at the data, you will note that since we only care about A,B,C,D’s that the…
C++ Visual Studio 2019 Write a program that asks the user for the name of a file. The program should display the contents of the file on the screen. Each line of screen output should be preceded with a line number, followed by a colon. The line numbering should start at 1. Here is an example: George Rolland 127 Academy Street Brasstown, NC 28706 If the file's contents won't fit on a single screen, the program should display 24 lines of output at a time, and then pause. Each time the program pauses, it should wait for the user to strike a key before the next 24 lines are displayed. Note: Save text below as the file to use and name it forChap12.txt file for this assignment. The line numbers should NOT be reset for each screen. Text: No one is unaware of the name of that famous English shipowner, Cunard. In 1840 this shrewd industrialist founded a postal service between Liverpool and Halifax, featuring three wooden ships with 400-horsepower paddle wheels and a burden of 1,162 metric…
File Display ProgramWrite a program that asks the user for the name of a file. The program should display thecontents of the file on the screen. If the file’s contents won’t fit on a single screen, the program should display 24 lines of output at a time, and then pause. Each time the programpauses, it should wait for the user to strike a key before the next 24 lines are displayed.
Line Numbers Write a program that asks the user for the name of a file. The program should display the contents of the file with each line preceded with a line number followed by a colon. The line numbering should start at 1. Python
C 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.
In C# create an application that writes a series of random numbers to a file. Each random number should be in the range of 1 through 100. The application should let the user specify how many random numbers the file will hold.
C++Inventory Program Write a program that uses a structure to store the following inventory data in a file: Item Description Quantity on Hand Wholesale Cost Retail Cost Date Added to Inventory The program should have a menu that allows the user to perform the following tasks: • Add new records to the file. • Display any record in the file. • Change any record in the file. Input Validation: The program should not accept quantities, or wholesale or retail costs, less than 0.The program should not accept dates that the programmer determines are unreasonable.
Item Counter Assume that a file containing a series of names (as strings) is named names.dat and exists on the computer’s disk. Design a program that displays the number of names that are stored in the file. (Hint: Open the file and read every string stored in it. Each time you read a string, increment a counter variable. When you’ve read all the strings from the file, the counter variable will contain the number of names stored in the file.) Note. Write pseudo code in Python.

This class allows you to use the print and println methods to write data to a file.1. File2. FileReader3. OutputFile4. PrintWriter
The File class contains file input and output operations. In other words, you can use the File class to read and write content from and to files. True False
in C# Code in VS studio: Create a program that has 2 options for a user to select. The first option accepts information from the user and then save that data to a file on disk. The second option loads all data stored on that file.
