Before you start to write the next script, first run the 'who' command at the UNIX prompt and redirect it into a file named users. txt. (Then, look at the file and study its format!) Afterwards, write a program that reads in and uses the 'split' function to break up each line of the 'users. txt' file into three variables: who, where, and when_and_IP, and then reprints it to the screen in this format: who on where at when_and_IP. So, if your text input file contains three lines, I expect to see code that produce three lines of output, each of which will look like:

Which option allows you to view slides on the full computer screen?

1. ask the user how many questions are in the quiz. 2. ask the user to enter the key (that is, the correct answers). there should be one answer for each question in the quiz, and each answer should be an integer. e.g., 34 7 13 100 81 3 9 10 321 12 might be the key for a 10-question quiz. you will need to store the key in an array. 3. ask the user to enter the answers for the quiz to be graded. there needs to be one answer for each question. note that these answers do not need to be stored; each answer can simply be compared to the key as it is entered. 4. when the user has entered all of the answers to be graded, print the number correct and the percent correct. 5. add a loop so that the user can grade any number of quizzes with a single key. after the results have been printed for each quiz, ask "grade another quiz? (y/n)." note: you only have one array (the key). you are not creating a new key for each set of quiz answers.
