Consider the following C program that manipulates newly created file named foo.txt. Write the contents of foo.txt after its execution. int main(int argc, char *argv[]) {close(STDOUT_FILENO); int f = open("foo.txt", O_CREATIO_WRONLY|O_TRUNC, S_IRWXU); assert (f >= 0); int rt = fork(); if (rt == 0) {write(f, "Child here!\n", 20); printf("Child terminates.\n"); } else if (rt > 0) { (void) wait(NULL); write(f, "Parent here!\n", 21); printf("Parent terminates.\n"); } return 0; }

In C++ PLEASE Use the text file from Chapter 12, forChap12.txt. SEE BELOW Write a program that opens a specified text file then displays a list of all the unique words found in the file. Addition to the text book specifications, print the total of unique words in the file. Text File = forChap12.txt No one is unaware of the name of that famous English shipowner, Cunard. In 1840 this shrewd industrialist founded a postal service between Liverpool and Halifax, featuring three wooden ships with 400-horsepower paddle wheels and a burden of 1,162 metric tons. Eight years later, the company's assets were increased by four 650-horsepower ships at 1,820 metric tons, and in two more years, by two other vessels of still greater power and tonnage. In 1853 the Cunard Co., whose mail-carrying charter had just been renewed, successively added to its assets the Arabia, the Persia, the China, the Scotia, the Java, and the Russia, all ships of top speed and, after the Great Eastern, the biggest ever…
Question 1 Write a Java program that prompts the user to enter a file name. Then the program counts and displays the number of letters and words in the file. You may use the following code fragment to extract and count the letters and words. int charchterCounter - 0; int wordsCounter - 0; String line; Scanner fileContent while (fileContent.hasNext ()) { line = fileContent.nextLine (); if(line.trim ().length () > 0) wordsCounter = wordsCounter + line. split (" ").length; for (int i - 0; i < line.length (): i++) if (Character.isLetter (line.charAt (i))) charchterCounter++

Milestone #1 - Ask Quiz Type In a file called main.py, implement a program that asks the user for a quiz type and prints the file name for that quiz type. The program should have one input prompt: the integer value of the personality quiz number. Your program should print the welcome message and the list of the personality quizzes, ask for the test number, and then print the file name. You are required to use the provided dictionary with the personality quizzes names. The list of the personality quizzes should be printed in alphabetical order. See example below. Welcome to the Personality Quiz! What type of Personality Quiz do you want to run? 1 BabyAnimals 2 Brooklyn99 3 Disney 4 Hogwarts 5 MyersBriggs 6 Sesame Street 7 - StarWars 8 - Vegetables
In Java I need to design an ESP Game: Design a program to test your extrasensory perception. The program will randomly pick a card (you could consider only the card suit, for example [Hearts, Diamonds, Clubs, Spades]. ) Prompt the user to enter a suit, then display whether the user guessed correctly. ESP Game Outcomes: Modify your ESP game to write the outcome of a game to a file. Allow the user to play the ESP game multiple times, writing each outcome to a file. Then, determine the number of times the user guessed correctly reading from the file. Please include flowcharts and/or class diagrams
