(Geometry: distance of two points)
Write a program that prompts the user to enter two points (x1, y1) and (x2, y2) and displays their distance between them.
The formula for computing the distance is:
Square root of ((x2 - x1) squared + (y2 - y1) squared)
Note that you can use pow(a, 0.5) to compute square root of a.
Sample Run
Enter x1 and y1: 1.5 -3.4
Enter x2 and y2: 4 5
The distance between the two points is 8.764131445842194
(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.
(Find the number of years)
Write a program that prompts the user to enter the minutes (e.g., 1 billion), and displays the number of years and days for the minutes. For simplicity, assume a year has 365 days.
Sample Run
Enter the number of minutes: 1000000000
1000000000 minutes is approximately 1902 years and 214 days

- Use C++ Programming language. Amanda and Tyler opened a business that specializes in shipping liquids, such as milk, juice, and water, in cylindrical containers. The shipping charges depend on the amount of the liquid in the container. (For simplicity, you may assume that the container is filled to the top.) They also provide the option to paint the outside of the container for a reasonable amount. Write a program that does the following: Prompts the user to input the dimensions (in feet) of the container (radius of the base and the height). Prompts the user to input the shipping cost per liter. Prompts the user to input the paint cost per square foot. (Assume that the entire container including the top and bottom needs to be painted.) Separately outputs the shipping cost and the cost of painting. Your program must use the class cylinderType (designed in Programming Exercise 3) to store the radius of the base and the height of the container.

Here, a magic number is a number whose sum of its digits eventually leads to 1.

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.

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.

(In Java Programming) See expected output below. 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. The first method should take no arguments and return an array list of doubles. 2. The second method…arrow_forward
- Summary When you borrow money to buy a house, a car, or for some other purposes, then you typically repay it by making periodic payments. Suppose that the loan amount is L, r is the interest rate per year, m is the number of payments in a year, and the loan is for t years. Suppose that i = (r / m) and r is in decimal. Then the periodic payment is (first image which R=....): You can also calculate the unpaid loan balance after making certain payments. For example, the unpaid balance after making k payments is (second image which L'=....) : where R is the periodic payment. (Note that if the payments are monthly, then m = 12.) Instructions Write a program that prompts the user to input the values of L, r, m, t, and k. The program then outputs the appropriate values. Your program must contain at least two functions, with appropriate parameters, to calculate the periodic payments and the unpaid balance after certain payments. Make the program menu driven and use a loop so that the…arrow_forward(Geometry: point in a circle?) Write a program that prompts the user to enter apoint (x, y) and checks whether the point is within the circle centered at (0, 0) withradius 10. For example, (4, 5) is inside the circle and (9, 9) is outside the circle, asshown in Figure 3.7a.(Hint: A point is in the circle if its distance to (0, 0) is less than or equal to 10.The formula for computing the distance is 2(x2 - x1)2 + (y2 - y1)2. Test yourprogram to cover all cases.) Two sample runs are shown below: Enter a point with two coordinates: 4 5Point (4.0, 5.0) is in the circleEnter a point with two coordinates: 9 9Point (9.0, 9.0) is not in the circlearrow_forwardPROBLEM:Write a program that prompts the user to input any digit then swap the position of the first and the last digit. Next, the user will be prompt to select what arithmetic operation he/she want to employ on the first and last digit based on the following choices: 1. Sum of their square 2. Product of their square root 3. Square of their product The output will display the result of the arithmetic operation followed by the digit with a swapped position of “first” and “last” digit. Then finally display the equivalent uppercase alphabet for the first digit and lowercase alphabet for the last digit respectively after swapping. Note: 1. If the last digit of the inputted digit from the user is zero, it must display that there is no equivalent alphabet for that digit. 2. If the user chooses arithmetic operation No.2, format the output to three decimal placesarrow_forward

Then, assign userNum with userNum multiplied by 3.arrow_forwardC++ One way to create a pseudo-random three digit number (and we are including one- and two-digit numbers as well) is rand()%1000. That gives numbers from 000 to 999, which is just what we want. Write a program that generates a random number and asks the user to guess what the number is. If the user's guess is too high then the program should display "Too high, try again." If the user's guess is lower than the random number the program should say "Too low, try again." The program should use a loop that repeats until the user correctly guesses the random number. The program should keep track of the number of guesses the user makes. When the user correctly guesses the random number, the program should display the number of guesses. As specified, have the program tell the player how many guesses were used. A good player should always be able to find a three-digit number in ten or fewer guesses. The programs needs to include a menu that allows the user to select easy (3 digit number),…arrow_forward
