A leap year in the Gregorian calendar system is a year that's divisible by 4 but not by 100, unless it is also divisible by 400. For example, 1896, 1904, and 2000 were leap years but 1900 was not. Write a function that takes in a year as input and prints whether it's a leap year (or not). In the program, ask the user to input a year and then call the function to determine whether the input year is a leap year or not. Display the result to the user.

Your friend kayla is starting her own business and asks you whether she should set it up as a p2p network or as a client-server network. list three questions you might ask to kayla decide which network to use and how her answers to those questions would affect your recommendation.

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.
