Question 1 Write a Java program that prompts the user to enter a file name. Then the program counts and displays the number of letters and words in the file. You may use the following code fragment to extract and count the letters and words. int charchterCounter - 0; int wordsCounter - 0; String line; Scanner fileContent while (fileContent.hasNext ()) { line = fileContent.nextLine (); if(line.trim ().length () > 0) wordsCounter = wordsCounter + line. split (" ").length; for (int i - 0; i < line.length (): i++) if (Character.isLetter (line.charAt (i))) charchterCounter++
Exercise 5: Write a Python program that reads each line of an input file original.txt and saves in a file called analysis.txt the line number, the number of words and characters found in that line without counting punctuations separating the words or found at the end of the line. For example, if the original.txt file is: In COMP2101, the students learn basic programming skills. Which includes: arithmetic and logical expressions, decisions, and loops. They will also learn how to read and write from keyboards and files. The file analysis.txt will contain Line1, 8 words and 48 characters Line2, 9 words and 61 characters Line 3, 13 words and 55 characters
JAVA PROGRAM Chapter 4. Homework Assignment (read instructions carefully) Write a program that asks the user for the name of a file.

2. Message Decoder Create a MessageDecoder program that reads from a file (one character at a time), and writes all non-numeric characters to a file called DecodedMessage.txt, displaying a secret (and motivational) message. ***Hint: .read() will return an int, but this can be type cast as a char. int and char are interchangeable (via type-caşting). You could run a loop on a condition like charInFile != (char) -1 Don't forget that -1 is a special character that denotes the end of a file!
Write a C program that counts the number of words and characters in a file. The program should do the following: Asks the user to input the name of the file to be opened. Display the contents of the file. Counts and displays the number of words and characters in a file. Exclude the spaces in the character count. Create a new file named “<inputted_file_name>_wordcharct.txt”, e.g. if the file name inputted in part a is “test.txt” then the file created should be named “test_wordcharct.txt”. Store the displayed information in this file. EXPECTED OUTPUT: Input the file name to be opened: test.txt The content of the file “test.txt” are: test line 1 test line 2 test line 3…
1. Create a file that contains 20 integers or download the attached file twenty-integers.txttwenty-integers.txt reads:12 20 13 45 67 90 100 34 56 89 33 44 66 77 88 99 20 69 45 20 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 file into 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.
B3- Write a Python program that reads the marks from a file named marks.txt and then increments each mark by 5 and saves the updated marks in a new file called updatedMarks.txt. You can assume that the marks are written on a separate line each in the marks.txt file. Finally, read the new marks from the new file and print them to the output screen.
Question 3: Write a program that reads a file of text and displays the number of words in that file. The filename is entered by the user. A Word is defined to be any number of consecutive letters (a...z, A...Z) only. Words are separated from each other by spaces (* “) and/or commas (*,') and/or semicolon (*;') and/or full stop (':'). Your program should write the words in the file "output.txt" along with the total word count. As shown below. file.txt Abedef, ;; gfdyire hsdhfkdsf, , ; , dkjfkjdljkfldj. .. mnbsdT .. ;; nbmxhs , a djks. output.txt Abcdef gfdyire hsdhfkdsf dkjfkjdljkfldj mnbsdT nbmxhs a djks Total count of words are = 8
ΡYTHON Write a program that first reads in the name of an input file, followed by two strings representing the lower and upper bounds of a search range. The file should be read using the file.readlines() method. The input file contains a list of alphabetical, ten- letter strings, each on a separate line. Your program should output all strings from the list that are within that range (inclusive of the bounds). Ex: If the input is: input1.txt ammoniated millennium and the contents of input1.txt are: aspiration classified federation graduation millennium philosophy quadratics transcript wilderness zoologists the output is: aspiration classified federation graduation millennium
