A supermarket awards coupons depending on how much a customer spends on groceries. For example, if you spend $50, you will get a coupon worth eight percent of that amount. The following table shows the percent used to calculate the coupon awarded for different amounts spent. Write a
Here is a sample run:

- (Simulation) Write a program to simulate the roll of two dice. If the total of the two dice is 7 or 11, you win; otherwise, you lose. Embellish this program as much as you like, with betting, different odds, different combinations for win or lose, stopping play when you have no money left or reach the house limit, displaying the dice, and so forth. (Hint: Calculate the dots showing on each die with the expression dots=(int)(6.0randomnumber+1), where the random number is between 0 and 1.)arrow_forwardProblem: A company wants a program that will calculate the weekly paycheck for an employee based on how many hours they worked. For this company, an employee earns $20 an hour for the first 40 hours that they work. The employee earns overtime, $30 an hour, for each hour they work above 40 hours. Example: If an employee works 60 hours in a week, they would earn $20/hr for the first 40 hours. Then they would earn $30/hr for the 20 hours they worked overtime. Therefore, they earned: ($20/hr 40hrs) + ($30/hr 20 hrs) = $800 + $600 = $1400 total. For this assignment, you must create pseudocode and a flowchart to design a program that will calculate an employee's weekly paycheck. . Write pseudocode to design a programming solution by outlining a series of steps and using appropriate indentation and keywords. As you write your pseudocode, be sure to consider the following: What input does the computer need? What steps does the program need to follow to process the input? What output should…arrow_forwardSimulate the dice game of lucky sevens. The rules are: roll two dice if the sum equals 7, win $4 if the sum is not 7, lose $1 Write a program that asks the user how much they would like start the game with. The program should then: simulate the dice roll (using the random function) and show what was rolled show what the user’s funds are after each roll ask the user if they want to roll again if the user wants to roll again, repeat the three actions above if the user does not want to roll again give some response and end the game the final output should show if they won or lost money, and how many rolls they playedarrow_forward
- 1. Write a program that lets the user guess whether a randomly generated integer would be even or odd. The program randomly generates an integer and divides it by 2. The integer is even if the remainder is 0, otherwise odd. The program prompts the user to enter a guess and reports whether the guess is correct or incorrect.arrow_forwardThis example creates a program to teach a first grade child how to learn subtractions. The program randomly generates two single- digit integers number1 and number2 with number1 > number2 and displays a question such as "What is 9 – 2?" to the student. After the student types the answer, the program displays a message to indicate whether the answer is correct.arrow_forwardCollatz Sequence: In 1937, Lothar Collatz proposed that no matter what number you begin with, the sequence eventually reaches 1. This is widely believed to be true but has never been formally proved. Write a program that inputs a number from the user, and then displays the Collatz Sequence starting from that number. Stop when you reach 1. If n is even, divide it by 2 to get n / 2. If n is odd, multiply it by 3 and add 1 to get 3n + 1. Repeat the process indefinitely. Find out and print the maximum number that you can get in these calculations. ' Part-3: Please enter a number: 2051 6154 3077 9232 4616 2308 1154 577 1732 866 433 1300 650 325 976 488 244 122 61 184 92 46 23 70 35 106 53 160 80 40 20 10 5 16 8 4 2 1 The maximum number you get: 9232arrow_forward
- Note: write a Jave Progame below Question2: Suppose a retail business sells an item that is regularly priced at $98 and is planning to have a sale where the item s price will he reduced by 25 percent. You have been asked to write a program to calculate the sale price of the item. To determine the sale price you perform two calculations: you get the amount of the discount, which is 25 percent of the item's regular price. you subtract the discount amount from the item's regular price. This gives you the sale price.arrow_forwardQuestions 1. Write a program which asks the user to enter a six-digit number and print a new number by subtracting 1 to each of its digits. For example, if the number entered is 393201, the output should be displayed as 282190. Information on the console should be displayed similar to the Sample Run shown below. Sample Run: Enter a 6 digit number: 393201 Modified number is: 28219darrow_forwardGuess The Number Game: write a program that will ask the user to guess a secret numberrandomly generated by your program between 1-10. Player have 3 trials to guess the number.After each trial, you have to inform the user, either he/she has guessed it correctly or not, andthe remaining trials to guess the number. In each trial your program should generate a newrandom number. If user guess at least twice correctly, then shows the message, “you won by 2-1” and vice versa for losing.When game is over, ask the user to play again: If the user types "yes", the game start again.else stop the game.arrow_forward
- Write a program that helps a company manage salaries of its employees. Your program should ask for the number of hours worked and the hourly rate of an employee than, display the salary. This program still asks the user to enter the information of many employees until enters a zero value. Sample Run: Enter the number of hours worked (negative nbr to end): 32 Enter hourly rate of the worker: 100 Your salary is $3200 Enter the number of hours worked (negative nbr to end): 40 Enter hourly rate of the worker: 5 Your salary is $200 Enter the number of hours worked (negative nbr to end): 42 Enter hourly rate of the worker: 10 Your salary is 5420 Enter the number of hours worked (negative nbr to end): 0arrow_forwardA retail company assigns a $5000 store bonus if monthly sales are more than $100,000; otherwise a $500 store bonus is awarded. Additionally, they are doing away with the previous day off program and now using a percent of sales increase to determine if employees get individual bonuses. If sales increased by at least 4% then all employees get a $50 bonus. If they do not, then individual bonuses are 0. Step 7: The final step in completing the pseudocode is to call all the modules with the proper arguments. Complete the missing lines. Module main () //Declare local variables Declare Real monthlySales Declare Real storeAmount Declare Real empAmount Declare Real salesIncrease //Function calls Call getSales(monthlySales) Call getIncrease(salesIncrease) Call ______________(_______________, _____________) Call ______________(_______________, _____________) Call ______________(_______________, _____________) End Modulearrow_forward4. A software company sells game cartridges for $99. Quantity discounts are given according to the following: 10 - 19 20% discount 20 49 O 30% discount 50 – 99 O 40% discount 100 + O 50% discount Write a program that asks the user how many games they purchased. The program should then display the amount of the discount (if any) and the total amount of the purchase after the discount is applied. Don't forget to add HST. 5. Earlier we wrote a BMI calculator. Enhance the program so that it displays a message indicating whether the person has optimal weight (BMI between 18.5 and 24.9), is underweight (BMI is less than 18.5), is overweight (BMI between 25 and 29.9), or is obese (BMI 30 or higher).arrow_forward
