For activities with output like below, your output's whitespace (newlines or spaces) must match exactly. See this note. Write code that outputs variable num_books as follows. End with a newline. Ex: If the input is 3, then the output is: Books: 3 1 123456 2 Our tests will run your program with input 3, then run again with input 6. Your program should work for any input, though. *** 3 num_books = input() Your code goes here

Write code that reads in a value for variable numCucumbers and then outputs as follows. End with a newline. Ex: If the input is 9, then the output is: The store has 9 cucumbers. /Our tests will run your program with input 9, then run again with input 6, then again. Your program should work for any input, though.
Input a number n and print out n lines of text in the pattern below, shown for example n = 5 * * * * 1 * * * 2 1 * * 3 2 1 * 4 3 2 1 5 4 3 2 1 There is exactly one space between numbe4rs, there is no space at the end of each line, and each line ends with a newline. The first two tests will ignore the whitespace.
Two bugs are positioned a given distance apart. The first bug moves halfway towards the other. The second bug moves halfway to the first. The first bug again moves halfway to the second. Compute and print the positions of the bugs. The initial position will change with each program run. // Declare position 2... /* Your code goes here */ double distance = initial_distance; 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27} // Update distance and position1 distance distance * 0.5; position1= distance; cout << position1 << " " << position2 << endl; // Update distance and position2 /* Your code goes here */ cout << position1 << " " << position2 << endl; // Update distance and position1 /* Your code goes here */ cout << position1 << return 0; "1 << position2 << endl;
You will build a program to manage a race car in this assessment. The code will consist of a for-loop method that will run a car around a race track and cause “wear and tear” on the car. The car will perform x number of laps and will have to make pitstops when it either runs out of gas or needs a tire replacement. The for loop will be simple def wear_tires(car): tire -=1 def use_gas(car): gas -=1 c = Car() # You need to make this part for i in range(100): if the car needs a pitstop: perform pitstop else: wear_tires(c) use_gas(c) # Display the current cars wear in a much better format print(c.tire) print(c.gas) print(“Current Lap is: “ , i) For this task, you will have to use this for loop and build out the two methods in the main Python program. To use the above code, you must build two pieces of information. An abstract Vehicle class A Car class A RaceCar class Each with its methods and variables. This programming will involve using inheritance and abstraction to make a race car…
Write a program that lets the user play the game of Rock, Paper, Scissors against the computer. The program should work as follows:1. When the program begins, a random number in the range of 1 through 3 is generated. If the number is 1, then the computer has chosen rock. If the number is 2, then the computer has chosen paper. If the number is 3, then the computer has chosen scissors. (Don’tdisplay the computer’s choice yet.)2. The user enters his or her choice of “rock,” “paper,” or “scissors” at the keyboard.3. The computer’s choice is displayed.4. A winner is selected according to the following rules:• If one player chooses rock and the other player chooses scissors, then rock wins. (Therock smashes the scissors.)• If one player chooses scissors and the other player chooses paper, then scissors wins.(Scissors cuts paper.)• If one player chooses paper and the other player chooses rock, then paper wins. (Paperwraps rock.)• If both players make the same choice, the game must be…
Write code that outputs variable numDogs as follows. End with a newline. Ex: If the input is: 3 the output is: Dogs: 3 I tried to get the output of 6 by its wrong everytime.
I have the code for this one but I do seem to be missing something. This is the question - Modify the CountByFives application so that the user enters the value to count by. Start each new line after 10 values have been displayed. This is the code I have. I have got one check right but I can't get the other two - import java.util.*; public class CountByAnything { // Modify the code below public static void main (String args[]) { Scanner input = new Scanner(System.in); final int START; System.out.print("Please enter the value: "); START = input.nextInt(); final int STOP = 500; final int NUMBER_PER_LINE = 10; for(int i = START; i <= STOP; i += START) { System.out.print(i + " "); if(i % NUMBER_PER_LINE == 0) System.out.println(); } } }
canMove(int x, int y, int destX, int destY, Side s): This method returns true if the player of color s can move the piece at coordinates (x,y) can move to coordinates (destX, destY) on the board in its current state. This means that here you do need to consider this piece’s interaction with other pieces on the board. Conditions for this method to return false are given in the code. public boolean canMove(int x, int y, int destX, int destY, Side s){ /* TODO write a method that checks if a piece at coordinates x,y can move to coordinates destX,destY Conditions for false: - Origin or destination coordinates are outside the board - Piece at origin is null - If source and destination coordinates are the same - Piece at origin is not of the same side as s - You can check this using piece.getSide() - Piece cannot move to the destination by piece movement rules - You should check this using Piece.canMove(destX,…
Write a program with the most appropriate loop that repeats user entered number of times (say the variable counts holds that number), asking the user counts times to enter numbers. The loop should also calculate the sum and the average of the numbers entered. Be sure to include the following: A class header with an appropriately named class. A main method. Use Scanner class for keyboard input. Declare and initialize any necessary variables. Use appropriate loop statement. Display any necessary input prompt and the output.
In various applications, you are often asked to compute the mean and standard deviation of data. The mean is simply the average of the numbers. The standard deviation is a statistic that tells you how tightly all the various data are clustered around the mean in a set of data. For example, what is the average age of the students in a class? How close are the ages? If all the students are the same age, the deviation is 0. Write a program that prompts the user to enter any number of values into a double array, and then calculates and displays the mean and standard deviations of these numbers using the following formulas: (z - mean) z+z3+ *** +zn deviation = mean = n-1 Required Methods You must write your program so that the following methods are defined/implemented and used (called): • /* Compute the deviation of double values */ public static double deviation (double[] x) • /* Compute the mean of an array of double values */ public static double mean (double[] x) Sample Run (user input…
Using Math.max and/or Math.min, write a class MaxOrMin, and make sure touse Math.max and Math.min which does the following: a. Create a Scannerb. Declare two variables, number1 and number 2c. Ask the user to enter 2 numbersd. Using the information above, print messages displaying the highest and lowest values ora message if the numbers are equal. The messages should look like the sample outputbelow Tip• Use if-else statement Submission• Copy and paste your code• Screen shot the console with user input of three examples Sample Run Enter a number 5Enter a number 9The lowest value is 5The highest value is 9 Enter a number 24Enter a number 11The lowest value is 11The highest value is 24 Enter a number 12Enter a number 1212 and 12 are equal
