*11.15 (Area of a convex polygon) A polygon is convex if it contains any line segments that connects two points of the polygon. Write a program that prompts the user to enter the number of points in a convex polygon, enter the points clockwise, then displays the area of the polygon. For the formula for computing the area of a polygon, see http://www.mathwords.com/a/area_convex_polygon.htm. Here is a sample run of the program:

8.12 (Simulation: The Tortoise and the Hare) In this exercise, you’ll re-create the classic race of the tortoise and the hare. You’ll use random-number generation to develop a simulation of this memorable event. Our contenders begin the race at “square 1” of 70 squares. Each square represents a possible position along the race course. The finish line is at square 70. The first contender to reach or pass square 70 is rewarded with a pail of fresh carrots and lettuce. The course weaves its way up the side of a slippery mountain, so occasionally the contenders lose ground. There is a clock that ticks once per second. With each tick of the clock, your program should use function moveTortoise and moveHare to adjust the position of the animals according to the rules in Fig. 8.18 (view your book for the rules in the table). These functions should use pointer-based pass-by-reference to modify the position of the tortoise and the hare. Use variables to keep track of the positions of the…
4.15 LAB: Hailstone sequence Given a positive integer n, the following rules will always create a sequence that ends with 1, called the hailstone sequence: If n is even, divide it by 2 If n is odd, multiply it by 3 and add 1 (i.e. 3n +1) Continue until n is 1 Write a program that reads an integer as input and prints the hailstone sequence starting with the integer entered. Format the output so that ten integers, each separated by a tab character (\t), are printed per line. The output format can be achieved as follows:print(n, end='\t') Ex: If the input is: 25 the output is: 25 76 38 19 58 29 88 44 22 11 34 17 52 26 13 40 20 10 5 16 8 4 2 1
4.35 (Sides of a Triangle) Write an application that reads three nonzero values entered by the user and determines and prints whether they could represent the sides of a triangle. This is the example used for format: Enter·three·sizes,·separated·by·spaces(decimals·values·are·acceptable):4.5·5.5·3.5↵ A·triangle·could·measure·4.50,·5.50,·by·3.50.↵
20.5 LAB: Flip a coin Write a program that simulates flipping a coin to make decisions. The input is how many decisions are needed, and the output is either heads or tails. Assume the input is a value greater than 0. Ex: If the input is: 3 the output is: heads heads tails For reproducibility needed for auto-grading, seed the program with a value of 1. In a real program, you would seed with the current time. In that case, every program's output would be different, which is what is desired but can't be auto-graded. Note: A common student mistake is to seed before each call to random.randint(). But seeding should only be done once, at the start of the program, after which random.randint() can be called any number of times. Your program must define and call the heads_or_tails() function that randomly picks 0 or 1 and returns "heads" or "tails". Assume the value 0 represents "heads" and 1 represents "tails". Use Python, please.

Sections 7.2-7.5 *7.1 (Assign grades) Write a program that reads student scores, gets the best score, and then assigns grades based on the following scheme: Grade is A if score is > best – 10 - Grade is B if score is > best – 20; Grade is C if score is > best – 30; Grade is D if score is > best – 40; Grade is F otherwise. The program prompts the user to enter the total number of students, then prompts the user to enter all of the scores, and concludes by displaying the grades. Here is a sample run: Enter the number of students: 4 - Enter Enter 4 scores: 40 55 70 58 - Enter Student 0 score is 40 and grade is C Student 1 score is 55 and grade is B Student 2 score is 70 and grade is A Student 3 score is 58 and grade is B

4.21 (Find the Largest Number) The process of finding the largest value is used frequently in com- puter applications. For example, a program that determines the winner of a sales contest would input the number of units sold by each salesperson. The salesperson who sells the most units wins the con- test. Write a pseudocode program, then a Java application that inputs a series of 10 integers and deter- mines and prints the largest integer. Your program should use at least the following three variables: a) counter: A counter to count to 10 (i.e., to keep track of how many numbers have been input and to determine when all 10 numbers have been processed). b) number: The integer most recently input by the user. c) largest: The largest number found so far.
Revise Exercise 6.28 (Craps is a popular dice game played in casinos. Write a program to play a variation of the game, as follows:Roll two dice. Each die has six faces representing values 1, 2, ..., and 6, respectively. Check the sum of the two dice. If the sum is 2, 3, or 12 (called craps), you lose; if the sum is 7 or 11 (called natural), you win; if the sum is another value (i.e., 4, 5, 6, 8, 9, or 10), a point is established. Continue to roll the dice until either a 7 or the same point value is rolled. If 7 is rolled, you lose. Otherwise, you win.Your program acts as a single player.)to run it 10,000 times and display the number of winning games.
21.4 LAB: Parsing dates (Use Python) Write a program to read dates from input, one date per line. Each date's format must be as follows: March 1, 1990. Any date not following that format is incorrect and should be ignored. The input ends with -1 on a line alone. Output each correct date as: 3/1/1990. Hint: Use string[start:end] to get a substring when parsing the string and extracting the date. Use the split() method to break the input into tokens. Ex: If the input is: March 1, 1990 April 2 1995 7/15/20 December 13, 2003 -1 then the output is: 3/1/1990 12/13/2003
3.27 LAB: Login name Write a program that creates a login name for a user, given the user's first name, last name, and a four-digit integer as input. Output the login name, which is made up of the first six letters of the first name, followed by the first letter of the last name, an underscore (_), and then the last digit of the number (use the % operator). If the first name has less than six letters, then use all letters of the first name. Ex: If the input is: Michael Jordan 1991 the output is: Your login name: MichaeJ_1 Ex: If the input is: Nicole Smith 2024 the output is: Your login name: NicoleS_4
