A prime number is a whole number greater than 1 whose only can be divided by itself and 1. Thus, prime number contain only 2 divider (the number itself and 1). Write a program to check whether a number enter by user is prime number or not. If the entered number is 2, then the program should display as below: Checking for prime number Enter a number: 2 2 is a prime number If the entered number is 20, then the program should display as below: Checking for prime number Enter a number: 20 20 is not a prime number

Computer Science PYTHON PROGRAMMING Write a program that generates a random number in the range of 1 through 100, and asks the user to guess what the number is. If the user's guess is higher than the randomly generated number, the program should display "Too high, try again." If the user's guess is lower, the program prints "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. Keep track of the number of guesses a user makes before guessing the correct one and display it with the congratulatory message when the user guesses the number correctly. For this assignment, create functions that: generate and return a random number between 1 and 100. format and return the failure and congratulatory messages. Put these function in a module called helper.py and put the rest of the code in game.py. The game module must import the helper module. Please provide both helper.py & game.py…
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.
Exercise II Write a program that finds the positive integer solutions of the following equation ax³ + bx² + cx' + d = 0. The user enters the values of coefficients a, b, c and d. The program should test each integer starting from -50 to 50, and each time the equation is equal to zero, it prints its value as well as "is a solution". At the end, it displays the total number of positive integers found. Note that if the equation has more than one solution, the plural word “solutions" is used in the output. Sample run 1: Enter the coefficient of a, b, c, d: 1 -8.5 21 -13.5 1 is a solution 3 is a solution The equation has 2 integers as solutions Sample run 2: Enter the coefficient of a, b, c, d: 6 48 103.5 67.5 The equation has no integer solutions Sample run 3: Enter the coefficient of a, b, c, d: 1 -1 -12 0 4 is a solution The equation has 1 integer solution
Retail price calculator Write a program that asks the user to enter an item’s wholesale cost and its markup percentage. It should then display the item’s retail price. For example: • If an item’s wholesale cost is 5.00 and its markup percentage is 100 percent, then the item’s retail price is 10.00.• If an item’s wholesale cost is 5.00 and its markup percentage is 50 percent, then the item’s retail price is 7.50. The program should have a method named calculateRetail that receives the wholesale cost and the markup percentage as arguments and returns the retail price of the item.
Party-On sells individual hot/cold cups and dessert plates for parties. SueChen wants a program that allows her to enter the price of a cup, the price of a plate, the number of cups purchased, and the number of plates purchased. The program should then calculate the total cost of the purchase, including the sales tax. Finally, the program should display the total cost on the screen. Desk-check your solution’s algorithm using $0.50 as the cup price, $1 as the plate price, 35 as the number of cups, 35 as the number of plates, and 2% as the tax rate. Then desk-check it using $0.25, $0.75, 20, 10, and 6%.
Microwaves / Radio Waves If a scientist knows the wavelength of an electromagnetic wave she can determine what type of radiation it is. Write a program that asks for the wavelength in meters of an electromagnetic wave and then displays what that wave is according to the following chart. (For example, a wave with a wavelength of 1E-10 meters would be an X-ray.) 1x 10-11 1 x 10-8 4 x 10-7 7x 10-7 1x 10-3 1 x 10-2 Gamma Rays. X Rays Ultraviolet Visible Light Infrared
Box Office: A movie theater only keeps a percentage (20%) of the revenue earned from ticket sales. The remainder goes to the movie distributor. Write a program that calculates a theater’s gross and net box office profit for a night. The program should ask for the name of the movie, and how many adult and child tickets were sold. (The price of an adult ticket is $10.00 and a child’s ticket is $6.00.) Input: the name of the movie, number of adult tickets sold, number of child tickets sold Output: as specified below Object: cin, cout, getline, format output Note: 1. Movie names contain spaces 2, the report is aligned. 3. The decimal number is displayed with 2 decimal places.

Challenge Problem python G U E S S T H E N UM B E R Write a program that plays a guessing game with the user. The program should have the right answer set to 13, then prompt the user repeatedly to guess the number from 1 to 25. When the user guesses incorrectly, the game should give the user a hint about whether the correct answer is higher or lower than the guess. Once the user guesses correctly, the program should print a message showing the number of guesses that the user made. Note : This assignment involves the use of a while loop and if-else decision making controls. You CANNOT use the reserved keywords break and continue for any portion of this program or any program for that matter throughout this course.

The program should display two random numbers to be added, such as 247 +129 The program should then pause while the student works on the problem. When the student is ready to check the answer, he or she can press a key and the program will display the correct solution: 247 +129 376
Part 4 Add this comment: # Ass 1: Part 4 Write a program that generates a random number in the range of 1 through 100, and asks the user to guess what the number is. If the user's guess is higher than the random number, the program should display "Too high, try again." If the user's guess is lower than the random number, the program should display "Too low, try again." If the user guesses the number, the program should congratulate the user by displaying "You won, congratulations.". Samplel: Please enter your guess value: 10 Too low, try again. Please enter your guess value: 15 Too low, try again. Please enter your guess value: 30 Too low, try again. Please enter your guess value: 50 Too low, try again. Please enter your guess value: 60 Too high, try again. Please enter your guess value: 55 Too high, try again. Please enter your guess value: 53 You won, congratulations. Sample2:
