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

Directions: Typing make at the command line should create executable named bitflip. Only bitflip.c and Makefile are included in the input unless permission is given for any other files. Program should have consistent indentation. Code should be readable with good variable and function names. No use of "break or continue statements" except in a switch. Program must exit with a return code of 0 on success and an error code in other cases. The program used getopt to parse the command line. Whenever an error occurs on the command line the user is given the usage statement and an appropriate error message if needed. If the -o option is used the output will go to a file named as specified without changing the filename at all otherwise it will go to stdout. -e option works as specified using bitwise operations. -f option works as specified using bitwise operations. -a option works as specified using bitwise operations. -s option works as specified using bitwise operations. Program outputs…

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…
