A new seat discount system is required to help managers of Qatar Railways Company (Qatar Rail) determine how much discount they have given out. Every time the system runs, the discount rate may be specified by the managers or set to a suitable default. You are thusly required to produce a console application (using Java) that is ready to open the file M:\data\seats.txt which contains the seat’s data. Upon application launch, the system should ask the managers if they wish to specify a custom discount rate, this should be in the form of a yes / no question. When the managers say yes, the system should request the discount rate as input (from the keyboard) which will then overwrite the default discount rate . When the managers say no, the system should report (to the screen) the default discount rate (i.e. like the example given below). Next, the system should loop through the seat’s data, calculating and printing (to the screen) the seat type, seat price, number of bookings, discount…

You will need to create a class named ChatSesssion where it will have a constructor that will take in a parameter called filename. The file used is found here download. The constructor will create include the following variables: self.numLines = 0 self.TagsList = [] self.MembersList = [] self.TimesList = [] self.UniqueMembersList = [] self.UniqueTagsList = [] self.MessageList = [] It should open the file and begin reading each line and populating the variables above in a for loop f = open(filename, "r") records = f.readlines() for record in records: ............................ The file consists of Tags, Timestamps, Members, Users, and Messages. Because there are multiple members you will need to create a Unique members list that hold the name of the unique members as well as unique tags. The class should contain the following tags that will return the information above:…

Assignment3A: Diagnosis Checker: For years, patients have used websites like WebMD to pre-diagnosis themselves with a variety of illnesses before meeting with a doctor. As you might imagine, medical professionals believe this can lead to incorrect treatment. To combat this, a local hospital has asked you to develop a program that will help patients check if their symptoms match the online diagnosis. You will prompt the user to enter their illness. Based on this input, you will ask them if they are experiencing certain symptoms. Depending on their answer, your program will indicate if the Internet diagnosis is likely to be correct or not. The decision chart is shown below: • ● ● HGPS 0 Do they have brittle bones? If no, it is likely not HGPS ■ If yes, it is possibly HGPS Bokter Syndrome O Do they have a Vitamin C deficiency? If no, it is likely not Bokter Syndrome If yes, are they a sailor? . . Lupus . If no, it is likely not Bokter Syndrome If yes, it is possibly Bokter Syndrome
NumericAnalyzer will accept a list of 1 or more numbers as command line arguments. NOTE: Don’t prompt the user for input – this is an exercise passing values to your program via the command line! We’re forcing the user to “push” data values to the application rather than “pull” it from the user! Error checking: if the user fails to pass in parameters, the program will display an error message (of your choice) and exit early. EXTRA CREDIT (+5) Data Validation – flag non-numeric parameters as “invalid data” and exit early. The main() method’s String [] args argument values must be converted and assigned to a numeric/integer array and passed to an instance of NumericAnalyzer. (SEE EXAMPLE main() IMPLEMENTATION BELOW). main() should also be responsible for error checking logic. Your program will display the following information about the numbers provided by the user: The set of numbers provided by the user sorted ascendingly. NOTE: DO NOT implement your own sort algorithm! Part…
you will develop a small Java application with a GUI to help a business owner record the personal and salary information of the employees in his/her organization. We assume that there are at most 10 employees. Each employee has the following personal information: first name, last name, and social security number. In addition, each employee has an employment grade, basic salary, and allowances. There are three employment grades: A, B, and C. Your application should help the business owner to determine the total payment for each employee based on the following table: Grade A Total pay = Basic Salary + Allowances Grade B Total pay = Basic Salary + 1.1 * Allowances Grade C Total pay = 1.1 * Basic Salary + 1.2 * Allowances
Make use of C# in Visual Studio. The below form will represent the main form from which the user will navigate to the other forms. Meaning each button should be linked to the appropriate form. E.g. If button Manage Addresses is clicked the form managed addresses should be displayed. The Exit button should successfully terminate the program. Create a void method for each button and name them as follow: LinkToAddresses (), LinkToCustomers (), LinkToDrivers (), LinkToStatus (), and LinkToFreight (). The methods should be called under the appropriate button. For the exit button create a void method named AppExit () this should terminate the program.
In linux using C Programming Language, make a stopwatch with lap counter and total time calculator. The program will create two processes and they will start calculating time.One process will be used to calculate total time and the other will calculate lap time. The total time calculator process will keep on calculating time.In the lap time, calculator process when it reaches lap time limit, the process will display lap number and set its counter to zero and start calculating again. Take input of lap time and number of laps from the userand start the program. At the end, display total time from total time calculator process.
