A movie theater only keeps a percentage of the revenue earned from ticket sales. The remainder goes to the movie company. Create an application that calculates and displays the following figures for one night’s box office business at a theater:
- a. GROSS REVENUE FOR ADULT TICKETS SOLD. This is the amount of money taken in for ail adult tickets sold.
- b. NET REVENUE FOR ADULT TICKETS SOLD. This is the amount of money from adult ticket sales left over after the payment to the movie company has been deducted.
- c. GROSS REVENUE FOR CHILD TICKETS SOLD. This is the amount of money taken in for all child tickets sold.
- d. NET REVENUE FOR CHILD TICKETS SOLD. This is the amount of money from child ticket sales left over after the payment to the movie company has been deducted.
- e. TOTAL GROSS REVENUE. This is the sum of gross revenue for adult and child tickets sold.
- f. TOTAL NET REVENUE. This is the sum of net revenue for adult and child tickets sold.
The application s form should resemble the one shown in Figure 3-61.
Figure 3-61 Theater Revenue form in the Designer
Assume the theater keeps 20% of its box office receipts. Use a named constant in your code to represent this percentage. If the user fails to enter numeric values, display an appropriate error message and do not attempt to perform calculations. Use the following test data to determine if the application is calculating properly:

- What resources are used when a thread is created? How do these differ from those used when a process is created?arrow_forward(c) Consider the following set of processes: Process ID Arrival Time Priority Burst Time A 2 3 100 B 6 C 10 1 (highest) 2 40 80 D 16 4 (lowest) 20arrow_forward(3e) Test-and-Set. The Test-and-Set instruction is used in hardware to achieve synchronization. It can be defined in the following way: function Test-and-Set (var target: boolean): boolean; begin Test-and-Set:= target; target := true; end; Now show how the Test-and-Set instruction can be used to protect a critical region and hence achieve mutual exclusion (do not worry about satisfying the bounded waiting condition).

- Consider a system with three smoker processes and one agent process. Each smoker continuously rolls a cigarette and then smokes it. But to roll and smoke a cigarette, the smoker needs three ingredients: tobacco, paper and matches. One of the smoker processes has paper, another has tobacco and the third has the matches. The agent has an infinite supply of all three materials. The agent places two of the ingredients on the table. The smoker who has the remaining ingredient then makes and smokes a cigarette, signaling the agent on completion. The agent then puts out another two of the three ingredients, and the cycle repeats. Given below is a solution to the Cigarette-Smokers Problem. Give initial conditions for the semaphores as well as plausible values for the variables i & j and r & s, such that the agent and smokers are synchronized. Write a couple of sentences on why these initial conditions are necessary and sufficient. Solution: var a: array [0..2] of semaphore (initial condition =…arrow_forwardLevel-0 Diagram for this: A customer sends in an order form containing details of their order and their membership number. A check is made to verify that they are a member. When their order is verified, a check is made to validate that the items ordered are produced by the company. Next, the valid order is used to update the daily order file, and then used to create a shipping list and invoice, which are sent on to the Order Fulfilment System.arrow_forwardIn this assignment, you will use all of the graphics commands you have learned to create an animated scene. Your program should have a clear theme and tell a story. You may pick any school-appropriate theme that you like. The program must include a minimum of: 5 circles 5 polygons 5 line commands 2 for loops 1 global variable You may wish to use the standard code for simplegui graphics below: import simplegui def draw_handler(canvas): frame = simplegui.create_frame('Testing', 600, 600) frame.set_canvas_background("Black") frame.set_draw_handler(draw_handler) frame.start() Submit Your Code After you write your code here in the programming environment, you will check it and submit it as usual. However, the grader will only perform basic checks against some requirements. If your code passes, you should submit your work, and your teacher will manually grade your submitted work using a rubric.arrow_forward
