A slot machine is a gambling device that the user inserts money into and then pulls a lever (or presses a button). The slot machine then displays a set of random images. If two or more of the images match, the user wins an amount of money, which the slot machine dispenses back to the user. Design a program that simulates a slot machine. When the program runs, it should do the following: Ask the user to enter the amount of money he or she wants to insert into the slot machine.
Create an application that simulates a slot machine.
The application should let the user enter into a TextBox the amount of money he or she is inserting into the machine. When the user clicks the Spin button, the application should display three randomly selected symbols. (Slot machines traditionally display fruit symbols.
This is the question:
Write an application that displays every perfect number from 1 through 1,000. A perfect number is one that equals the sum of all the numbers that divide evenly into it. For example, 6 is perfect because 1, 2, and 3 divide evenly into it, and their sum is 6; however, 12 is not a perfect number because 1, 2, 3, 4, and 6 divide evenly into it, and their sum is greater than 12.
This is the code given:
public class Perfect {
public static void main (String args[]) {
// Write your code here
}
public static boolean perfect(int n) {
// Write your code here
}
}
Instructor note:
This lab is part of the assignment for this chapter.
HINT: 1). The decision means how many times to flip the coin. 2). Use a random integer variable to indicate the head or tail in each toss.
Java
Define a method named coinFlip that takes a Random object and returns "Heads" or "Tails" according to a random value 1 or 0. Assume the value 1 represents "Heads" and 0 represents "Tails". Then, write a main program that reads the desired number of coin flips as an input, calls method coinFlip() repeatedly according to the number of coin flips, and outputs the results. Assume the input is a value greater than 0.
Ex: If the random object is created with a seed value of 2 and the input is:
3
the output is:
Heads Tails Heads
Note: For testing purposes, a Random object is created in the main() method using a pseudo-random number generator with a fixed seed value. The program uses a seed value of 2 during development, but when submitted, a different seed value may be used…

- Write an application that simulates coin tossing inside of C#. Let the application toss a coin each time the user chooses the " Toss Coin " menu option. Count the number of times each side of the coin appears. Display the results. The application should call a separate method Flip that takes no arguments and returns false for tails and true for heads. [ Note: If the application realistically simulates coin tossing, each side of the coin should appear approximately half the time.]arrow_forwardDesign and implement an application that plays the High-Low guessing game with numbers. The program should pick a random number between 1 and 100 (inclusive) then repeatedly prompt the user to guess the number. Every time the user guess, inform him/her whether the guess is correct, or the guess is high or low.Continue accepting guesses until the user guesses correctly or chooses to surrender. Use a sentinel value to determine whether the user wants to quit. Count the number of guesses and display that value when the user guesses correctly. At the end of each game (either by quitting or a correct guess) prompt to determine whether the user wants to play again. Continue playing until the user chooses to stop. When the user stops playing, display the number of correct guesses and surrenders.The c++program should use suitable selection and repetition structures. The input process, guessing process and output must be organized into appropriate functions.arrow_forwardTrue or False?

- Write a program that generates a random number in the range of 1 through 1000, and asks the user to guess what the number is. If the user guess is higher than the random number, the program should display Too high, try again. If the users guess is lower than the random number, the program should display Too low, try again. If the user guesses the number, the application should congratulate the user and generate a new random number so the game can start over. If the user doesn't want to continue the game the user should type an appropriate stop symbol to terminate the program (such stop conditions were discussed in the class). For each game iteration, count the number of guesses made by the user and display them. The program should contain the following functions: check_guess(): this function checks if the user's guess is lower, higher or equal to the random number. random_gen(): function that generates one random number for one game iteration main(): the function where the program…arrow_forwardThis needs to be done in JAVA!!!
