Chapter 15, Problem 15.21PE
(Drag points) Draw a circle with three random points on the circle. Connect the points to form a triangle. Display the angles in the triangle. Use the mouse to drag a point along the perimeter of the circle. As you drag it, the triangle and angles are redisplayed dynamically, as shown in Figure 15.32b. For computing angles in a triangle, see Listing 4.1.

(Game: scissor, rock, paper) Write a program that plays the popular scissor–rock–paper game.
Rules: A scissor can cut a paper, a rock can knock a scissor, a paper can wrap a rock.
The program should randomly generates a number 0, 1, or 2 representing scissor, rock, and paper.
The program should prompt the user to enter a number 0, 1, or 2 and displays a message indicating whether the user or the computer WINs, LOSEs, or DRAWs.
(In Java) In the game Clacker, the numbers 1 through 12 are initially displayed. The player throws two dice and may cover the number representing the total or the two numbers on the dice. For example, for a throw of 3 and 5, the player may cover the 3 and the 5 or just the 8. Play continues until all the numbers are covered. The goal is to cover all numbers in the fewest rolls.
Create a Clacker application that displays 12 buttons numbered 1 through 12. Each of these buttons can be clicked to ‘cover’ it. A covered button displays nothing. Another button labelled Roll can be clicked to roll the dice. Include labels to display the appropriate die images for each roll. Another label displays the number of rolls taken. A New Game button can be clicked to clear the labels and uncover the buttons for a new game.
(IN C LANGUAGE) Cumulative Addition: Computer selects a number between 7 and 23 at random. User will only add 2, 3 or 5 numbers to reach that number.For example: To reach 14:
User will enter 5 5 2 2 (4 input).Also he can enter 2 2 2 2 2 2 2 (7 input) or 3 3 3 3 2 (5 input).

- "NEED ONLY CODE NO EXPLANATION" Harry has a big wall clock, that got hit while he was playing. Now, the minute hand doesn't rotate by the angle 2π/3600 each second, but now it moves according to different angle x. You can assume that coordinates of the centre of the clock are (0, 0) and the length of the minute hand is l. One endpoint of the minute hand is always located at the clock centre; the other endpoint is initially located at the point (0, l). One second later, Harry observes that this endpoint is at distance d above the x-axis, i.e., the y-coordinate of this endpoint is equal to d. Harry is curious about where the minute hand will be (specifically, its y-coordinate) after t seconds. Because t can be very large, Harry can't wait for that moment. Please help him to write a python code that prints a single line containing the output. Input: 4 2 2 Output 4arrow_forwardProblem Description: In the Whimsical Library, each book is enchanted with a magical code to ensure the protection of knowledge. The validation process for these magical codes involves a combination of mathematical spells. The validation process is described as follows: Take the sum of the digits at odd positions from left to right. Take the sum of the squared digits at even positions from left to right. If the absolute difference between the results from step 1 and step 2 is a prime number, the book code is considered valid; otherwise, it is invalid. Example 1: Consider the magical book code 86420137. Step 1. Take the sum of the digits at odd positions from left to right. 8+4+0+3=15 Step 2. Take the sum of the squared digits at even positions from left to right. 6^2+2^2+1^2+7^2=36+4+1+49 = 90 Step 3. If the absolute difference between the results from step 1 and step 2 is a prime number. 115-901 75 (not a prime number) Book code 86420137 is invalid.

Create a new Java application called "WeightedAvgDropSmallest" (without the quotation marks) according to the following guidelines. The program prompts the user for five to ten numbers all on one line, separated by spaces, calculates the weighted average of all those numbers except the lowest n numbers, where n and the weight are also given by the user, and displays all the numbers, the weight, the number of lowest numbers dropped, and the calculated average to the user. The program uses methods to: Get the numbers used to calculate the average. Get the number of lowest numbers to drop before calculating the average. Get the weight, a double greater than 0 and less than or equal to 1. Calculate the weighted average of the numbers (except the lowest n numbers) entered by the user. Print the results. 1.

- 4. Area of a Rectangle • Write a program that compares the area of two rectangles. You can do this several ways. one way is to add the length and width of each rectangle to get it's area and then compare the two areas together. • The program should ask for the length and width of two rectangles and then tell the user which rectangle has the greater area, or if the areas are the same. • The area of a rectangle is the rectangle's length times its width. Name the source code file yourName HW4.py. • Test and run the program. Capture the output console and save it as an image file named yourName HW4 output.jpg. • Submit the py and the image files through Canvas.

Write a method that checks whether a string is a valid password. Suppose the password rules are as follows: A password must have at least eight characters. A password consists of only letters and digits. A password must contain at least two digits. Write a program that prompts the user to enter a password and displays Valid Password if the rules are followed or Invalid Password otherwise.arrow_forward(Find future dates) Write a program that prompts the user to enter an integer for today’s day of the week (Sunday is 0, Monday is 1, …, and Saturday is 6). Also prompt the user to enter the number of days after today for a future day and display the future day of the week.arrow_forward

The user should be able to choose to roll eg 4 dice and test the probability of a selected score eg 11. The program should then do a number of simulations and answer how big the probability is for the selected score with as many dice selected. There must be error checks so that you cannot enter incorrect sums, for example, it is not possible to get the sum 3 if you roll 4 dice.

- (Display Magic Numbers) Display the first N magic numbers, where N is a positive number that the user provides as input. Here, a magic number is a number whose sum of its digits eventually leads to 1. For example, 1234 is a magic number because 1 + 2 + 3 + 4 = 10 and 1 + 0 = 1, while 1235 is not (1 + 2 + 3 + 5 = 11 and 1 + 1 = 2). Write a program that prints out the first N magic numbers, seven on each line. Here is the sample output: You are required to use the following function prototype: bool isMagic(int value); // Returns true if value is a magic number The outline of this function will be as follows: Step 1: Calculate the sum of digits of value Step 2: Repeat Step 1 until we get a single digit Step 3: If the resulting sum is equal to 1 then it is a magic number, otherwise notarrow_forward(Display Magic Numbers) Display the first N magic numbers, where N is a positive number that the user provides as input.
