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

1 Encryption (a). Write a program that will utilise AES for encrypting and decrypting the data from a file as follows. Your program should take 3 arguments from the command line as input. The first input should be either 0 or 1 referring to encryption or decryption, respectively. The second input is the key filename. The third input is the either the plaintext or encrypted filename. If the first argument is 0: your program will read an AES key from a file titled key.txt (passed as second argument) and then will read the plaintext from a file titled plain- text.txt (passed as third argument), encrypt the contents of plaintext.txt using the key and save the ciphertext in a file titled encrypted.txt. If the first argument is 1, your program should decrypt the contents of encrypted.txt. Sample Command-line Inputs: java 0 key.txt plaintext.txt java 1 key.txt encrypted.txt

Q4. Write an algorithm of a program to read from a file. The user should be able to get the option to input the file name. He is supposed to read first 100 bytes from the file. After the reading is done, the file should be closed. If the file is not available, the program should be closed immediately. You should mention "System call" beside each instruction which are supposed to use a system call function. *
All I need is the main.cpp file Programming Specifications: Task: Two files have been provided (wordcounter.h and wordcount.cpp). You must open a text file, read in each word until end of file, add each word to the WordCount library and print the report. Your program must request a filename of a text file that contains words to count. You must check to see if it is a valid file and issue an error message if not and request a new file name until a valid one is entered. You must have at least one function that either passes in a parameter and at least one function that returns a value. You can have a single routine that does both. You must declare the class object properly, use AddWord() to add the word to the catalog and use PrintSummary() to produce the output. Design Considerations: The file will contain only words (no punctuation or special characters) less than or equal to 13 letters. There will be no limit to the number of words. You must open the file and read each…
assume the file data.dat contains a sequence of binary data. write a program that does the following: displays the first 5 bytes stored in the file. each byte should be displayed on a separate line. starting with byte 0, displays every even-numbered byte in the file. (in other words, display byte 0, byte 2, byte 4, and so on.) each byte should be displayed on a separate line. starting with byte 1, displays every odd-numbered byte in the file. (in other words, display byte 1, byte 3, byte 5, and so on.) each byte should be displayed on a separate line. displays the last 5 bytes stored in the file, in reverse order. (display the last byte, then the next-to-last byte, and so on.) each byte should be displayed on a separate line. handle exceptions in the following manner: if a filenotfoundexception is thrown, the program should display the string "file error". if an eofexception is thrown, the program should display the string "eof error". if any other exception is thrown, the program…

Write a program using a for loop that creates a file and adds odd numbers that are in the integers 1 through 20 to the file. Name the file as numbers.txt. Then perform the following on the file: Read all of the numbers stored in the file and calculate their total. Display all the numbers in the file and the calculated total Using a for loop add the following numbers to the file 21 through 30 Delete the following numbers from the file 24, 25, 26 (using a temp.txt file) Change the number 11 to 50 (using a temp.txt file)
Please in C Language Write a program that uses an existing text file (text.txt) to determine the number of occurrences of each letter. You can assume that the file is filled with only lowercase letters and only the letters from a-z are present! Write the result in a new file to be created by the program! Errors when opening and closing the files must be caught Data.txt I love my money
1. Write a program that reads student scores from a file and then writes the scores with a corresponding grade to another file. Assume integer scores whose valid range is 0–100. An invalid score will be given the grade X. Use a function to assign a grade based off the grading scale below. 90 – 100% A 80 – 89% B 70 – 79% C 60 – 69% 0 - 59% F a. Create a file named scores.txt. Place it in the same folder as your C program. Fill it with the values below. 95 30 65 500 b. Ifa wrong input file name is entered, an error message should be displayed, and your program should stop with no output file created. c. Ifa correct input file name is entered, the program should ask you for the name of the output file and then fill it with the right values as shown in sample output 2. Once done, it should display a message in the main program letting the user know that data has been saved to the output file. Please note that the values in green in sample output 2 would be the contents of the output file…
