Suppose you can buy a chocolate bar from the vending machine for $1 each. Inside every chocolate bar is a coupon. You can redeem seven coupons for one chocolate bar from the machine. You would like to know how many chocolate bars you can eat, including those redeemed via coupon, if you have n dollars.
For example, if you have 20 dollars then you can initially buy 20 chocolate bars. This gives you 20 coupons. You can redeem 14 coupons for two additional chocolate bars. These two additional chocolate bars give you two more coupons, so you now have a total of eight coupons. This gives you enough to redeem for one final chocolate bar. As a result you now have 23 chocolate bars and two leftover coupons.
Write a program that inputs the number of dollars and outputs how many chocolate bars you can collect after spending all your money and redeeming as many coupons as possible. Also output the number of leftover coupons. The easiest way to solve this problem is to use a loop.

- Let's begin with a lesson in roulette. Roulette is a casino game that involves spinning a ball on a wheel that is marked with numbered squares that are red, black, or green. Half of the numbers 1–36 are colored red and half are black and the numbers 0 and 00 are green. Each number occurs only once on the wheel. We can make many different types of bets, but two of the most common are to bet on a single number (1–36) or to bet on a color (either red or black). These will be the two bets we will consider in this project. After all players place their bets on the table, the wheel is spun and the ball tossed onto the wheel. The pocket in which the ball lands on the wheel determines the winning number and color. The ball can land on only one color and number at a time. We begin by placing a bet on a number between 1 and 36. This bet pays 36 to 1 in most casinos, which means we will be paid $36 for each $1 we bet on the winning number. If we lose, we simply lose whatever amount of money we…arrow_forwardWrite a program that plays a game with a single die (or dice). Each number on the die is worth a certain number of points. If the person rolls a six, then that roll is worth 4 points. If the person rolls a five, then that roll is worth 3 points. If the person rolls a three, then that roll is worth 2 points. All the other rolls (four, two or one), that roll is worth 1 point. The rules of the game is that the player rolls the die five times, and adds them up. If the total adds up to a number greater than or equal to 15, then the player gets a rating of excellent. If the total adds up to a number greater than or equal to 12 but less than 15, then the player gets a rating of above average. If the total adds up to a number greater than or equal to 7 but less than 12, then the player gets a rating of good. If the total adds up to a number less than 7, then the player gets a rating of poor. After the game is over, the program should ask the user if they want to play again. In…arrow_forwardWrite a program that will figure out the required change for a purchase. Start by asking the user for the price of the product and the amount paid. (We are expecting that the user will give a larger value for the amount paid.) Read in each of these values as a double. Report back to the user the number of each denomination of change due. You are not just telling the user the amount of money he gets back. Hint: Working with integers is much easier. The modulo operator is your friend for this assignment. Also, note that pennies can be tricky due to the poor real number to binary conversions. (Remember that 1.00 could actually be stored as 0.9999999999997.) Do not include five-dollar bills, ten-dollar bills, etc. Only show coins and one-dollar bill amounts. Be sure to test multiple values. There is a test case below. Your program should run the test case exactly as it appears below, and should work on any other case in general. Output Example (User input is marked with >>>.…arrow_forward
- Suppose you are a computer salesman and your income depend on the total sales and commissions earned for the computers that you sell. Commission rates vary depending on how many units you sold (see chart below). Your income equals to the total sales plus the commission where the commission equals to total sales times the commission rate. That is, commission = total sales * commission rate and income = total sales + commission. Total Sales Commission rate % Less than 200 sold 8% (totalsales < 200) Greater or equal to 200 sold 10% (totalsales >=200 & totalsales <400) Greater than to 400 sold 12% (if (totalsales >= 400) Use Multiway if, else if (use as many you need) and else correctly Review slides 3-CH-2 Slide 4 and 8 Write the code correctly as show in the chapter slides.

You have w white dominoes (2×1 tiles, the two cells are hued in white) and b dark dominoes (2×1 tiles, the two cells are shaded in dark). You can put a white domino on the board in case both board's cells are white and not involved by some other domino. Similarly, you can put a dark domino if the two cells are dark and not involved by some other domino.

- There are a dozen eggs in a basket; some are hard boiled and some are raw. The object of this game is for the user to guess the number of hard-boiled eggs prior to playing the game. The computer then simulates cracking all 12 eggs, using a random number 0 or 1 to simulate raw or hard boiled. The number 0 should represent raw eggs and the number 1 should represent hard boiled. The computer must keep track of the number of hard-boiled eggs. At the conclusion of cracking all 12 eggs, the actual number of hard boiled is compared to the user’s guess, and whether the user won or lost is given as output.

In order to answer this question, you need to know a few things: Each bacterium (a single bacteria) can create 2 more bacteria every hour This means that after one hour, the doorknob will have 10 + 10 * 2 = 30 bacteria, since we started with 10 bacteria and each of those created 2 more. This means that after two hours, the doorknob will have 30 + 30 * 2 = 90, since there were 30 bacteria at the beginning of hour two, and during that hour each bacteria created 2 more bacteria. Continuing this pattern, the number of bacteria on the doorknob after N hours is numberOfBacteriaLastHour + numberOfBacteriaLastHour * 2 However, if we wanted to know how many bacteria are alive after 12 hours, we need to know how many bacteria were alive at hour 11.

- Using Dart. Create a program that will play the “cows and bulls” game with the user. The game works like this: Randomly generate a 4-digit number. Ask the user to guess a 4-digit number. For every digit the user guessed correctly in the correct place, they have a “cow”. For every digit the user guessed correctly in the wrong place is a “bull.” Every time the user makes a guess, tell them how many “cows” and “bulls” they have. Once the user guesses the correct number, the game is over. Keep track of the number of guesses the user makes throughout the game and tell the user at the end.arrow_forwardIn cpp Room contains nx n cubes (in rows and in columns). Each cube is white or black. You can get out of a white cube by going in one of the four directions horizontally or vertically (but you can't go outside the room). You can enter a black cube, but you can't exit it. There is a mouse and a piece of cheese in the room. The mouse is in a cube (0,0) - white, and the cheese in a cube (n-1, n-1) - black. The mouse can move from cube to cube according to the rules described above.

Two players take turns clicking an available cell in a grid with their respective tokens (either X or O). When one player has placed three tokens in a horizontal, vertical,or diagonal row on the grid, the game is over and that player has won. A draw (no winner) occurs when all the cells in the grid have been filled with tokens and neither player has achieved a win. Figure 12.17 shows the representative sample runs of the example. Assume that all the cells are initially empty, and that the first player takes the X token and the second player the O token. To mark a cell, the player points the mouse to the cell and clicks it. If the cell is empty, the token (X or O) is displayed. If the cell is already filled, the player’s action is ignored.Define a custom class named Cell that extends Label for displaying a token and for responding to the button-click event.
