- 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…arrow_forwardC lanaguge Managing Student Information! C LANGUAGE We're going to build a student information management system. The user should be shown a menu with four options: display student initials, display student GPAs, add students, or exit the program. If the user chooses to exit, the program should end. Otherwise, if the user chooses to display the student initials, the contents of the students.txt file should be read, and just the student number and initials should be displayed to the user in a tabular format. If the user chooses to display the student GPAs, the contents of the students.txt file should be read, and just the student number and GPAs should be displayed to the user in a tabular format. If the user chooses to add students, they should be prompted for the number of studnets they’d like to add. They should then be prompted that many times for a studnet number, a GPA, a first initial, and a last initial. Each of the new items should be saved to the students.txt file.…arrow_forwardFile Operations:Write a complete program that reads integers from a file called numbers.txt, and displays their sum on the screen. Example: If the content of numbers.txt is: 10 20 30 100 The program should print: 160arrow_forward

It writes a new file that has the same contentsas the argument, except that all of the phone numbers are redacted. Assume that the filename has onlyone period in it. The new filename is the same as the original with '_redacted' added before theperiod. For instance, if the input filename were 'myfile.txt', the output filename would be'myfile_redacted.txt'. Make sure you close your output file.The first hard task in this function is to make the output filename from the input filename that waspassed in. You can break it into two pieces by splitting on the dot or by using the index method andslicing. Then put it back together again using string concatenation.We are also working with files in this one. To open a file with a filename stored in the variable fname,in read mode use the open function as such: fp = open(fname). You will need to open the outputfile in write mode: open(fname, 'w'). Then you can traverse the…arrow_forwardRandom Number File Writer Write a program that writes a series of random numbers to a file. Each random number should be in the range of 1 through 500. The application should let the user specify how many random numbers the file will hold. * Please use the Python program.arrow_forward
- 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.

BoyNames.txt This file contains a list of the 200 most popular names given to boys born in the United States from the year 2000 through 2009. Write a program that reads the contents of the two files into two separate lists. The user should be able to enter a boy’s name, a girl’s name, or both, and the application will display messages indicating whether the names were among the most popular. **programming language is python** ** must use a def main(): function** *please include some comments* i aslo have the .txt files but no wya to upload themarrow_forward

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 tons. Eight years later, the company's assets were increased by four 650-horsepower ships at 1,820 metric tons, and in two more years, by two other vessels of still greater power and tonnage. In 1853 the Cunard Co., whose mail-carrying charter had just been renewed, successively added to its assets the Arabia, the Persia, the China, the Scotia, the Java, and the Russia,…arrow_forwardCreate an inputfile named "inputFile.txt" (use "Note Pad") that contains the following data.
