Write a C
then copies it to another file in reverse order. That is, the last byte becomes the first,
the byte just before the last one becomes the second, etc.
The program call should look like:
reverse fileIn fileOut

- Write a C program, called reverse, using standard I/O functions, to take a file as inputthen copies it to another file in reverse order. That is, the last byte becomes the first,the byte just before the last one becomes the second, etc.The program call should look like:reverse fileIn fileOutSubmit your source code and script filesUsing only standard I/O functions (like fopen(), fseek(), ftell(), fgets(), etc.), write a C program to reverse the order of the lines in a text file. That is the first line becomes last, the second line becomes the one before the last one and so on. Note: your program should have two arguments, the input file name and the output file name. Call model: reverseFile Input file:HelloI am happy to see youOutput file:I am happy to see youHelloThis is Python Program 5: Improve the file copy program from Lab 9 so that it will make sure the user enters a file that exists. If a file doesn’t exist, the open function will raise the FileNotFoundError. You do not need to check if the destination exists since a file doesn’t need to exist to write it. Instead of copying the content of the source as exact, it only copies non-empty lines and it also prepend each line with a line number. A line is empty if the length of the line stripped of white space from both end is 0. The code segment below shows how to strip white space and getting the length of the string. If the length of the line is zero, the line is a blank line. line1 = " " line2 = " aa " print(len(line1.strip())) # 0 print(len(line2.strip())) # 2 In the sample run, “add.py” is the source file and “add-copy.py” is the destination file. Note that “add-copy.py” contains only non-blank lines from “add.py” and each line in “add-copy.py” is labelled with a line number. Sample run:…
- In Python Define a function writeScores with two parameters. The first should be the name of a file, and the second should be a list of integer scores. The set of scores should be appended to the given file, one score per line.Write a program in C/C++ which is passed as command line argument a file name. Your program will readdatafrom the file using read system call. The program will then pass the contents of the file to a pipe and create a child process. The child process will read the file’s content from the pipe.The child process does two things to the file data: 1) it removes all integers from the pipe. 2) It changes the case of all alphabets. The child process then writes the modified file data to the second pipe. The parent then reads this data from the second pipe andwrites the data(using write system call)to a new filewhose name is also passed as command line argument.The input file from which the data will be read has no size restrictionUsing Programming C++..... a) Write a program that reads a text file in which each line in the file consists of a first name, a last name, following by 4 grades (double types) like Tim Hanes 78.3 98.0 80.5 72.3 The program must read every line of the text file, find the average of the 4 grades then print the names followed by the averages (one name per line) in a second file as well as on the monitor. b) Create the text file with at least 5 entries with the format given in part (a). Give the absolute path of the file in your computer. Test your program in part 2(a) on this file.
- Write a C program that gets a source file name from a user. If the file does not exist, it will generate a proper error and exits.If the file exists, it also gets the name of two more files from the user, say destination1 and destination2. These files don’t need to exist as they are files that need to be written to. If the files cannot be opened for writing, a proper error will be generated. The program then reads the source file line by line. It will copy every line that has a digit in it to destination 2 and lines that have no digit in them to destination 1. Feel free to use ctype’s isdigit() function to identify digit characters. Example: If source file is:Hi My name is VeriaHello My name is John. How can I help you?I have a problem with my giga bit internet. The speed should be around 1000 but it’s just 200 Sure! I can help with that. Can I have your number in case we get disconnected? Sure! My number’s 647-123-1234 First file (destination 1) should be Hi My name is Veria Hello…Write a program that reads integers from a file, sums the values and calculates the average. Write a value-returning function that opens an input file named txt. You may "hard-code" the file name, i.e., you do not need to ask the user for the file name. The function should check the file state of the input file and return a value indicating success or failure. Main should check the returned value and if the file open fails, output a message to cout and exit the program. Write a void function that reads the integers from the data file, sums the values and calculates the average of the values. Return the sum of the values, number of values read and the average of the values to the calling module, main. Since you do not know the number of values in the file, you must check for end of file. In main, output to cout the sum, number of values read and the average. Include the function prototypes Declare the variables necessary to create a running program. Write statements for all…Write a C++ program that reads first name and last name from two txt files, input1.txt and input2.txt respectively and stores them in two separate arrays. Then merges these two arrays into another txt file output.txt. Example: Intput1.txt: Markus Input2.txt: Stocker Output.txt: Markus Stocker
- In C write a program that takes a file name and two strings as command line arguments, and writes the longer of the two strings to the file with the given name. If the given strings are the same length, write the first string given to the file. If the user does not provide the correct number of command line arguments, print an error message and exit the program with a non-zero exit code.use c code to Write a C program that gets a source file name from a user. If the file does not exist, it will generate a proper error and exits.If the file exists, it also gets the name of two files from the user, say destination1 and destination2. These files don’t need to exist as they are files that need to be written to. The program then reads the source file line by line. If the line starts with an uppercase and ends with a lower case, it copies that line to dest1 (first destination file) If the line starts with a lowercase and ends with a dot (‘.’), it copies that line to dest2 (second destination file) If neither of the above hold, the program discards that line (doesn’t copy it anywhere) The program then displays a report mentioning how many lines were copied into each destination file. Don’t forget to close all the files. Example: Assume that the source file is (<NL> = new line, <EOF> end of file): Souce: “myfile.txt” This is my first…Write a program in C/C++ which is passed as command line argument a file name. Your program will read data from the file using read system call. The program will then pass the contents of the file to a pipe and create a child process. The child process will read the file’s content from the pipe.The child process does two things to the file data: 1) it removes all integers from the pipe. 2) It changes the case of all alphabets. The child process then writes the modified file data to the second pipe. The parent then reads this data from the second pipe andwrites the data(using write system call)to a new filewhose name is also passed as command line argument.The input file from which the data will be read has no size restriction. Sample file could have data like: M7 9am3 1k H23is e750n
