Requirements Write a program that creates a loop and has three options for the user to select. Option 1 allows the user to add a user name and password, which is then stored into a file. Option 2 allows the user to enter a user name and password up to three times. For a given attempt, the user will be notified if the attempt is successful or unsuccessful. Option 3 will exit the loop and end the program Main Menu Requirements: When the program starts, present the user with a menu offering the three options described above. After the user chooses either option 1 or 2, the program should go back to the main menu. The final option will end the program. Option 1 Requirements: This option prompts the user for their user name and password and stores them in a file named passwords.txt. The program should not o...

Multithreading and JavaFX Create an object-oriented JavaFX GUI that shows two shapes or images moving around a GUI. Each shape will have its thread to move it around the GUI. You must use threads – not AnimationTimelines or JavaFx Paths- this is a threading homework that happens to use JavaFx- not just a JavaFx homework. You must have two separately distinct activities. Two flashing texts are only one different activity. I have provided an example of how to move an image in a circle and flashing text using threads. You may choose one of these, but your second activity must be different from shooting and moving in a circle. Do not directly copy the examples- you may use the algorithm with other things. Try moving in an up-down, side to side, zig-zag, etc. Be sure to shut down all threads when the Application closes. (Hint: interrupt() method on Thread class) Your program should consist of multiple classes. Put thread Runnable classes in a different class from Application and pass shared...

Description: Write a C++ program to assign passenger seats in an airplane. Chesapeake Airlines is a small commuter airline with seats for 36 passengers in 9 rows of 4 seats each. See the sample display below for a layout of the plane. The user enters the row (1 – 9) and the seat (A – D). The program checks the array to see if the seat is available. An X in the array indicates the seat is not available. If the seat is available, assign an X to that position in the array. If it’s unavailable, display a message to the passenger. There are 3 ticket classes: Row 1 = First Class Rows 2-4 = Business Class Rows 5-9 = Coach *Note that the rows are 0-8 in the C++ program. Use the classCtr array supplied in the header file to keep track of how many seats in each class are purchased. Continue processing requests until the user enters -1 for the row. After -1 is entered for the row, display number of seats sold. percentage occupied. sales report. You need to include the following functions in your ...
