- Introduction to Computer Systems Project 1 Due: February 09, 2023 by 5:00 PM Spring 2023 Introduction: xxd command in Linux creates a hex dump of a given file or standard input. It's simple. For example, suppose you have a text file 'test.txt' with contents as shown below: The isprint() function checks whether a character is a printable character or not. Check more information in: https://www.programiz.com/c-programming/library-function/ctype.h/isprint Here's how you can use xxd to convert the file contents into hex: $ xxd test.txt And here's the output: 00000000: 5468 6520 6973 7072 696e 7428 2920 6675 00000010: 6e63 7469 6f6e 2063 6865 636b 7320 7768 00000020: 6574 6865 7220 6120 6368 6172 6163 7465 00000030: 7220 6973 2061 2070 7269 6e74 6162 6c65 00000040: 2063 6861 7261 6374 6572 206f 7220 6e6f 00000050: 742e 0a43 6865 636b 206d 6f72 6520 696e 00000060: 666f 726d 6174 696f 6e20 696e 3a20 6874 00000070: 7470 733a 2f2f 7777 772e 7072 6f67 7261 00000080: 6d69 7a2e 636f 6d2f 632d 7072…Write a Program in CWrite 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: Sample 1: Input the file name to be opened: test.txtThe content of the file “test.txt” are: test line 1 test line 2 test line 3 test line 4 -----End of File---- The number of words in the file “test.txt” are: 12 The number of characters in the file “test.txt” are: 36The file “test_wordcharct.txt” containing the results was created successfully! Sample 2: (use this one in creating the program) Input the file…you should create a program that takes a file name as an argument, and prints the hex dump of it. help to solve by java
- I am trying to write a program in PYTHON that will open a file named StudyHours.txt. The program will read in data from a text file named StudyHours.txt. The user of the program will be prompted to correct any bad data. The program updates the corrected information in StudyHours.txt file. For example if the file contains a letter grade of K which is not a possible letter grade(possible grades are A,B,C,D,F). The StudyHours.txt file contains this info: Aaron Rodgers 12 A Tom Brady 9 K Philip Rivers 3 c Joe Theismann 15 B As you can see there is a K listed for a grade for Tom Brady. How do I change that K to a valid grade by prompting an input from the user and then recording that change in the StudyHours.txt file so that the file reads: Aaron Rodgers 12 A Tom Brady 9 A (changed from K to what the user inputs)- say the user inputs an A Philip Rivers 3 c Joe Theismann 15 B This is what I have to start with. Assume the file is opened and the \n is stripped. while gradeDesired > 'F' or…In Python IDLE Write a program that reads the file’s contents and determines the following: The number of uppercase letters in the file The number of lowercase letters in the file The number of digits in the file The number of whitespace characters in the file Then the program should do a mass replacement of all spaces with a ‘-‘, and then replace any uppercase letters with lowercase letters. After the replacement of the spaces, the count of letters, digits, and spaces should be rerun, the number of replacements indicated, and a second report of letters, digits and spaces should be printed. Save the results of the changes in a file named “testoutput.txt”. This file must be submitted as part of the submission for your lab. Output should look like this: Uppercase letters: 20 Lowercase letters: 310 Digits: 4 Spaces: 82 >>> Hint: This program does not need to use any lists – the entire file can be read into one string. Problem 2. Date Printer - Write a program…Create a program that reads three lines from a text file. Each line should be read one at a time. For each word on a line, the user should be asked to specify how many syllables are in that word. The program should then inform the user if the file contains a valid Hiku using the function below: def isHiku (firstLine, secondLine, thirdLine):if (firstLine == 5 and secondLine == 7 and thirdLine == 5): return True return False print("The file contains a Hiku:", isHiku(5,7,5))Note: You must replace the values in the function with the numbers counted by your program.
- Doubly Linked List This assignment asks you to sort the letters in an input file and print the sorted letters to an output file (or standard output) which will be the solution. Your program, called codesolve, will take the following command line arguments: % codesolve [-o output_file_name] input_file_name Read the letters in from the input file and convert them to upper case if they are not already in uppercase. If the output_file_name is given with the -o option, the program will output the sorted letters to the given output file; otherwise, the output shall be to standard output. In addition to parsing and processing the command line arguments, your program needs to do the following: You need to construct a doubly linked list as you read from input. Each node in the list will link to the one in front of it and the one behind it if they exist. They will have NULL for the previous pointer if they are first in the list. They will have NULL for the next pointer if they are last in the…The program takes a single argument as the name of the file to be read. A sample file is named (Movies.txt). The program reads this file which has labeled columns separated by commas. Every row of this text file includes information about a movie. You are asked to read every row as a string and decompose the given information (separated by commas). If a costumer wants too see "List of the Genres" (or genre,score,year) all genres type must be show. I need this answer in C language. Please explain nicely. Thanks.Write a python code that reads a file (contents of the file pasted below) and shows the average of all values shown in the last column.

Your program should first ask the user for the name of the file and then count the number of individual words and characters (including numbers and punctuation) in the file. The word and character count result should be printed on the screen. Furthermore, your program should count the number of individual words starting with the letter 'A', 'B', 'C' and so on to 'Z'. Again, these statistics should be printed on the screen. Your program should display the letter that appears at the start of most words. The program must be written in C. You should illustrate the operation of your program by generating a text file containing 3 sentences from a lead news story on the day of testing.
