Question

Transcribed Image Text: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 program in c++, that lets the user go through a text file and replace one given character with another, for example change ever occurrence of the letter C to the letter D. Ask the user for the file name to read from and the file name to write to, and ask the user for the letter to be replaced and the new letter.arrow_forwardWrite a program in cpp that gives and takes advice on program writing. The program starts by writinga piece of advice to the screen and asking the user to type in a different piece of advice. The program then ends.The next person to run the program receives the advice given by the person who last ran the program. The adviceis kept in a file, and the contents of the file change after each run of the program. You can use your editor to enterthe initial piece of advice in the file so that the first person who runs the program receives some advice. Allow theuser to type in advice of any length so that it can be any number of lines long. The user is told to end his or heradvice by pressing the Return key two times. Your program can then test to see that it has reached the end of theinput by checking to see when it reads two consecutive occurrences of the character ‘\n’.arrow_forwardWrite a C program that takes the name of a text file as a input, reads its contents, and then replaces all vowels in the file with the symbol "#". After that it should write back the modified content in the same file and display the message indicating that the file has been successfully modified.arrow_forward
- Write a Java program that reads from a URL and searches for a given word in the URL and creates a statistic file as an output. The statistic file needs to include some information from the URL. URL address Number of words in the URL page Number of repetitions for a given word displays the number of times the word appears. You need to have two functions, one for reading from the URL and the other function for searching the word.arrow_forwardWrite a cpp program that contains class “candidate”. A candidate has a name, number of electoral votes and number of popular votes.In your program, write a function that reads an input file containing elections results using input file stream and output to the console the name of the winner, his electoral votes and his popular votes.Your function should be prominent to faulty data; for example, if the number of votes for one of the candidates was a negative number, the function should exit and print a proper error message on the screen (You must use exceptions to do this)arrow_forwardWrite a java program that will generate a permuterm index from the terms in the files in an input directory. The program should prompt the user for a single directory and find all of the terms (after processing) in each file in it. The program should then find the permutations of each term and store them (keeping track of the original word each permutation comes from). After all of the text files in the directory have been read, the output of the program should display the permutations in sorted order along with the original term. Use the dollar sign as the end of term symbol.arrow_forward
