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 and writes the data (using write system call) to a new file whose name is also passed as command line argument. The input file from which the data will be read has no size restriction.

Write a C++ program that asks the user for a file name and a word for which to search. The program should search the file for every occurrence of the word. When the word is found, the line it contains should be displayed. After all of the occurrences have been found, the program should display the number of times the word was found in the file.
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 fileOut
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.
Write a C++ program that counts the number of non white-space characters in an input text file. Program takes as command argument(s) the name of the input file (and the output file with option -f). Based on the option flags, it displays the output on the standard output, or writes the output to an output file. The command format is as follows:command -f inputfile outputfile or, command -s inputfile -f indicates writing to an output file;-s indicates displaying the output on the screen. Also notice the errors caused by incomplete arguments. Including: (1) The name of the author of the program (your name) and the date it was written, (2) a concise description of what the program does, (3) a clear description of its limitations if it does not meet all specifications, and (4) explanation for critical code and data declarations. The same should also be done for each function written in the program.
Write a C program named toupper.c that reads the contents of a file, and writes to another file after changing all lowercase letters in the input file to uppercase. The name of the input file and the output file are to be passed as command line arguments. Assume there are only ASCII characters in the input file. The length of the input file is not known beforehand. So make sure your program keeps reading bytes until EOF is reached. Use the library function toupper to concert letters into uppercase. Example: The program is run from the command line as follows; C:\>toupper.exe infile.txt outfile.txt Suppose the contents of the input file infile.txt is: AbcdefG The contents of the output file outfile.txt should be: ABCDEFG
Implement in C Programming 9.9.1: LAB: Thesaurus 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 the synonyms within the file are grouped according to the synonyms' first letters, separated by an '*'. 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 two-dimensional array of char* predefined in the program. Finally the program searches the array 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 malloc() function to allocate memory for each of the synonyms stored in the array. A string always ends with a null character ('\0'). Use ASCII values to map the row index of the array to the…
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 C++ program that prompts the user to enter a file name that contains the scores of students in a quiz. Each line in the input file contains a student name followed by the student’s score (as shown in the sample file to the right). The program should then find out the students with the minimum score and the maximum score and display their names and scores. Marks.txt Ahmed 90 Badria 85 Noor 91 Khalid 70 Said 65 Suha 80
You must solve the problem in C++. (Process scores in a text file) Suppose that a text file Exercise13_3.txt contains an unspecified number of scores. Write a program that reads the scores from the file and displays their total and average. Scores are separated by blanks.
Write C++ Program that does the following: •Instead of reading data from the user, create a txt file that will be imported into the code •The format of the file is: –First line: number of records –Subsequent lines: Last name on a line by itself First name and three homework grades •Read function: parameters are –An instream, passed by reference, from which to read the data –Fields for firstname, lastname, grade1, grade2, grade 3 •The read function should read in the data from the instream. It is a void function •What types are the parameters? How will you pass them? •Write function: parameters are –Firstname, lastname, grade1, grade2, grade3, average grade, letter grade –What types are those parameters? Do you need to pass them by reference? •The write function will write the data to the screen formatted neatly –Which formatting instructions will you need to use? Overall program flow: •Open the file in the main program. •Read in the number of records •For each record,…
Using the Seek() Method in C#In the next steps, you use the Seek() method to reposition a file pointer so you canaccess a file from any location. The user will be prompted to enter a number representinga starting point to list the names in the Names.txt file. Names from that pointforward will be listed, and then the user will be prompted for another selection.1. Start a new program named AccessSomeNames that demonstrates howto access requested names from the Names.txt file you created in theCreateNameFile application.Searching a Sequential Text File using System;using static System.Console;using System.IO;class AccessSomeNames{static void Main(){FileStream file = new FileStream("Names.txt",FileMode.Open, FileAccess.Read);StreamReader reader = new StreamReader(file);
Write a C program that, given a text file, constructs Huffman code based on the character frequencies of the file and then encodes the file accordingly. The executable must accept the following command line options:• -i filename for the input file • -o filename for the output file Use the fread function, use FILE, size, etc. Please use the following to write the code: #include <stdio.h> #include <stdlib.h> #include <string.h> #include <getopt.h>
