Write a program that allows the user to navigate lines of text in a file. The program should prompt the user for a filename, read the file and input the lines of text into a list. The program then enters a loop in which it prints the number of lines in the file and prompts the user for a line number. Actual line number range from 1 to the number of lines in the file. If the input is 0, the program quits. Otherwise, the program prints the text associated with that number.

C++ Visual 2019    A file called num.txt.  write a C++ program that opens a file, reads all the numbers from the file and calculates the following: The number of numbers in the file The sum of all the numbers in the file (a running total) The average of all the numbers in the file The program should display the number of numbers found in the file, the sum of the numbers and the average of the numbers. These are the numbers in the num.txt file :…

please save number random and file and when print on monitor read from file and every num in single line

What does the following python code do? f = open("sample.txt", "a") Choose all that apply.    Select 3 correct answer(s) Question 15 options:   opens a file called sample.txt for reading   reads the file called sample.txt starting from the top   writes "a" to the file called sample.txt    opens a file called sample.txt for appending   If the file called sample.txt exists, it writes at the bottom of the file   closes a file called sample.txt   if the file sample.txt exists, deletes everything in it   if the file sample.txt does not exist, it creates the file and opens it for writing

PYTHON PROGRAMMING LANGUAGE   Create a new text document called names.txt (this is done by hand - not using programming) with the following names: Adam, Bryan, Charlie. Each name should be followed by a hard return (do not store them in a list). Main Function. Write a program where the user enters a name. Using the read function, check to see if the name is in the text document. If it is, respond back to the user the name is found within the list. Read Function.  The read function should return the contents of the text document as a list.  Write Function.  The write function should take the list and override the file with the new names list in reverse alphabetical order with a hard return after each name. EXAMPLEPlease enter a name: AdamAdam is found in the list.Enter another name (Y/N): YPlease enter a name: AndrewSorry, Andrew was not found in the list. Would you like to add it? (Y/N): YAndrew has been added to the list.Enter another name (Y/N): N LIST EXAMPLEadambryancharlie Final…

C 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.…

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…
