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.)

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.
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.

- (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.

The theater has two rows of five seats each. Each row is referred to by number (1 or 2) and each seat in the row is referred to by letter (A, B, C, D, and E). When started, the program should ask the user for the row they prefer (row selection). If that row has no empty seats then the program should ask the user if they prefer the other row, if no then display a message stating the next show is tomorrow. Upon selecting a row, the program should present the user with a choice of available seats in the row. The user can then either choose a seat and print the ticket (in this case a simple message will suffice) or return to row selection. If a ticket is printed the program should return to row selection.

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_forward
- PYTHON programming solotion Develop a program that allows the user to enter a start value of 1 to 4, a stop value of 5 to 12 and a multiplier of 2 to 8. The program must display a multiplication table with results using these values. For example, if the user enters a start value of 3, a stop value of 7 and a multiplier value of 3, the table should be displayed as follows: Multiplication Table 3 x 3 = 9 3 x 4 = 12 3 x 5 = 15 3 x 6 = 18 3 x 7 = 21 additionally Each multiplication problem must be displayed with a problem number. The program must prompt the user to enter an answer to each of the multiplication problems. The correct answer should be displayed after the user enters an answer. A message should be displayed informing the user that the answer entered was correct or incorrect followed by an appropriate motivating comment. A running record of the number of correct and incorrect responses must be kept. After all the problems have been presented the user must be informed of…arrow_forwardAssignment Write a program that tracks how much steps the user walks in total in a day and reports if the daily target is reached or not. The program will keep reading double values, each representing steps walked during an individual activity within a day (stepsWalked) until either the user enters a negative value or the daily target of 5000 steps is met. If the user enters a negative number, the program should print total steps walked as a double. Otherwise, if the target is exactly reached, the program should simply print "Target is reached", finally if the target is surpassed the program should print the text "Target is surpassed by", followed by the excess amount above the target as a double, and finally printing the text "steps". NOTE: You MUST use a repetitive statement in this question. NOTE: Each stepsWalked value will be given as a non-negative value. You do NOT need to check this.

- Problem: A small company needs an interactive program to compute an employee’s paycheck. The payroll clerk will initially input the data, and given the input data, an employee's wage for the week should be displayed on the screen for the payroll check. The data for the employee includes the employee's hourly pay rate and the number of hours worked that week. Wage is equal to the employee's pay rate times the number of hours worked (up to 40 hours). If the employee worked more than 40 hours, wage is equal to the employee's pay rate times 40 hours plus 1½ times the employee's pay rate times the number of hours worked above 40. Instructions: Match the action at the left-side with the correct step number at the right-side (the attached picture). Note that it may be possible to group more than one related actions in the same logical step / process without altering the essence of the algorithm. In the program flow, input and checking of hourly pay rate should come before that of the number…arrow_forwardComputer 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.

Tally the number of correct and wrong guesses that the player has made. After every round, display the tally (correct, wrong, and score) After a cycle the program will ask the user if he wants to continue playing. This is a console project.
