Simulate 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 played
Coin Exchange:
Write a program that will determine how many coins of each denomination (50kr, 25kr, 10kr, Skr, and 1kr) are required to make up a given amount of change.
For example, to make 57kr we could use 1 x 50kr, 1 x 5kr, and 2 x 1kr.,
It should be obvious that many combinations of coins are possible. For example, in the example above, we could make up 57kr with: (57 x 1kr) or (2 x 25kr and 7 x
1kr). However, your program must use the smallest number of coins (10 points).
Example program output:
Enter amount: 40
40 Kr =
1 x 25Kr
1х 10Кr
1 x 5Kr

- Pythonarrow_forwardTHIS MUST BE DONE IN CORAL: Cracked Egg Game: 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. The goal of this milestone is to use Coral to program one of the loops you will need for your finalized program in Project Two. This will help you define the logic, flow, and sequence of the game. For this work, you will write code in Coral for your selected programming game by accessing the activity in the zyBook.

For an integer x, print:• “Fizz” if x is only divisible by 3,• “Buzz” if x is only divisible by 5,• “FizzBuzz” if x is divisible by both 3 and 5,• the number x if it is not divisible by both 3 and 5.This problem is the extreme version of Fizz Buzz. You are given a list of K distinct integers A and a list of K characters S. Both lists are numbered from 1 to K. The integer Ai corresponds to the character Si. Denote B as the subset of A. There will be a rule for each possible subset: if an integerx is only divisible by all elements in B, print a string which is the concatenation of the corresponding character of each element in B, sorted by the index in ascending order. However, if B is an empty subset, print the first digit of x instead. Does it look complicated? Do not worry, as it is just a generalization of the regular Fizz Buzz. For example, if A = [3, 5] and S = [F, B], you will get the normal Fizz…arrow_forward
- Write a program that displays all possible combinations for picking two numbers from integers 1 to 7. Also display the total number of combinations.arrow_forwardA robot sits in a 30 foot square room. It be directed to travel a randomly generated distance between 8 and 20 feet. The user will input a value that will serve as the seed for the random number generator. Every foot it travels it indicates that it has traveled 'x feet'. Upon arrival at the user specified distance, it announces." made it!"(This will happen even if the robot moves 0 feet). The program should also indicate how many more feet the robot could travel before running into a wall assuming it always starts at one wall of the room. Note that grammar used to indicate singular versus plural distances. i.e. for an random generation of 5, the resulting output should be: How far should the robot travel? 5 feet 1 foot I made it! I can only travel 25 mor 2 feet 3 feet 4 feet 5 feet e feet. tabs are used to space the output of traveled feet 330492.1753326.qx3zay7 LAB АCTIVITY main.cpp 1 #include 2 using namespace std; 3 4 int main() int roomsize - 30; 6 int distance = 0; 7 8 cout <«…arrow_forwardThe Game of Nim: The game of Nim starts with a random number of stones between 15 and 30. Two players alternate turns and on each turn may take either 1, 2, or 3 stones from the pile. The player forced to take the last stone loses. The computer player will make random choices during their turn. Your program must check to make sure that neither the computer nor the human player attempts to take 3 if there are only 1 or 2 stones left. The computer should only take 1 or 2 stones when 3 are left, and only 1 stone when 2 stones are left. Make sure you are using functions, importing random, and making it at around grade 10 coding levels, haha!arrow_forward
- You have a maze with obstacles and non-zero digits in it: 9+ 7 8 + 4 1 2 3 4 5 You can start from any square, walk in the maze, and finally stop at some square. Each step, you may only walk into one of the four neighbouring squares (up, down, left, right) and you cannot walk into obstacles or walk into a square more than once. When you finish, you can get a number by writing down the digits you encounter in the same order as you meet them. For example, you can get numbers 9784, 4832145, etc. The biggest number you can get is 791452384, shown in the picture above. Your task is to find the biggest mumber you can get. Input There will be at most 25 test cases. Each test begins with two integers R and C (2 < R,C < 15, R+C < 30), the number of rows and columns of the maze. The next R rows represent the maze. Each line contains exactly C characters (without leading or trailing spaces), each of them will be either # or one of the nine non-zero digits.
