Write a program that gets 2 or more command-line arguments. The last argument is a file that the program will send its output to. The other arguments are names of input files that already exist and that contain integers. The program opens each of the existing input files, in the order given by the arguments, and reads and sums all the integers of each file, writing the name of th Input file followed by its sum to the output file (given by the last argument). EXAMPLE: 1f the program were invoked like this: a.out fileA fileB filezzz and if the content of fileA was "398" and that of fileB "4 1" then the output written to filezzz would be: fileA 20 fileB 5 1 of 1 Sun Mar 13 2022 11:4138 GMT-0400 (EDT)

- Write a program that reads two input files whose lines are ordered by a key data field. Your program should merge these two files, writing an output file that contains all lines from both files ordered by the same key field. As an example, if two input files contain student names and grades for a particular class ordered by name (the key field), merge the information as shown below. File 1 and file 2 are supplied. Here is an algorithm to merge the data from two files: Read a line from each data file While the end of both files has not been reached While the end of both files has not been reached Write the line from file 1 to the output file and read a new line from file 1. Else Write the line from file 2 to the output file and read a new line from file 2. Write the remaining lines (if any) from file 1 to the output file. Write the remaining lines (if any) from file 2 to the output file. See the Merging Filesslides attachedto the project in Canvasfor a visual look at this algorithm.Write a program that reads student data from a file, compute their GPA and writes the results to a different file. 1. The user should have the option to either enter their text file that contains the student grades or use the provided text file that contains theinformation.

TheReverseText program should reads the characters from the first file and write them into the second file inreverse order. Test your program out using the small text file iso_8859-1.txt provided with thisassignment. Once you are confident that your program is working correctly, run it on the much larger fileWar_of_the_Worlds.txt uploaded along with this assignment. For example, when you use this program on the command line it should be like this:ReverseText.exe War_of_the_Worlds.txt War_of_the_Worlds_reversed.txt Remember, if you are using fgets(), it will only return one line of the book at a time. You willhave to go through the book multiple times and make frequent use of the rewind() function.HintYou can use the strlen() function (that is part of the string.h C Standard Library) to check thelength of the string you read in using fgets().

- Write a program countfile.c that calculates and prints on screen the number of bytes or number of lines in a file. To print the number of lines in the file myfile.txt, the program is run from the command line with two arguments as follows countfile.exe -l myfile.txt or, to print the number of bytes in the file myfile.txt, it would be run as countfile.exe -b myfile.txt EXAMPLE: Suppose the file myfile.txt contains the following samantha jacob 58 91 Then running countfile.exe -l myfile.txt would print 4 on the screen. And running countfile.exe -b myfile.txt would print 15 on the screen. If as a switch anything other than -l or -b is used, the program should give an error message and exit with code 1. If the file is not found, then it should give a message saying no such file exists, and exit with code 2. If everything runs correctly the program should return 0.Write a program that prompts the user for an input file name, reads all words from the input file, and writes the words to the output file named sentences.txt. Start a new line whenever a word ends in a period, question mark, or exclamation mark.Write a program to read two file names from the command line. If the number of arguments in the command line are more than or less than two, then the program should terminate with an appropriate error message. Otherwise, it should open the first file and copy its contents into the second file, in effect overwriting its contents, if any.
- Write a program that reads student information from a text file, then creates a text file that records the course grades of the students and a final grade. Each row of the .txt file contains the Last Name, First Name, Midterm1 score, Midterm2 score, and the Final score of a student, each separated by a space. A sample of the student information is provided in StudentInfo.txt below. Assume the number of students is at least 1 and at most 20. The program performs the following tasks: • Read the file name of the .txt file from the user. • Open the .txt file and read the student information using readline() or readlines(). • Compute the average exam score of each student. • Assign a letter grade to each student based on the average exam score in the following scale: ◦ A: 90 =< x ◦ B: 80 =< x < 90 ◦ C: 70 =< x < 80 ◦ D: 60 =< x < 70 ◦ F: x < 60 • Output the first names, last names, exam scores, and letter…consider a program that reads data from a text file called: "klingon-english.txt" (shown below). How would one construct such a program with the following conditions: 1. Ask the user to choose a Klingon consonant they want to practice with. Ask again if the user’s answer is not a valid Klingon consonant, until the user enters a valid consonant. 2. Find a Klingon word that starts with the chosen consonant (the text file contains only one word that starts with any given consonant, so you don’t need to use the random library) 3. Ask the user to translate the chosen word into Klingon 4. Print "Correct" if the user’s answer is correct 5. Print "Sorry, you’re wrong!" if the user’s answer is wrong 6. Print The correct answer is ... if all three user’s answers are wrong You will also factor in this version: 7. If the answer is incorrect, show the first hint: the first and last characters of the correct Klingon word. When showing a hint, replace all other characters with a star (*) 8. If the…Write in Python: Given a set of text files containing synonyms for different words, complete the main program to output the synonyms for a specific word. Each text file contains synonyms for the word specified in the file’s name, and each row within the file lists the word’s synonyms that begin with the same letter, separated by a space. The program reads a word and a letter from the user and opens the text file associated with the input word. The program then stores the contents of the text file into a dictionary predefined in the program. Finally the program searches the dictionary and outputs all the synonyms that begin with the input letter, one synonym per line, or a message if no synonyms that begin with the input letter are found. Hints: Use the first letter of a synonym as the key when storing the synonym into the dictionary. Assume all letters are in lowercase. Ex: If the input of the program is: educate c the program opens the file educate.txt, which contains: brainwash brief…
