Use case diagram2. State machine diagram3. Class diagram Case StudySoftware has to be developed for automating the manual railway reservation system. The system shouldhave distributed functionalities as described below:-1. RESERVE SEATA passenger should be able to reserve a seat in the train specified by him if available. For this he has tofill a reservation form with the details about his journey. The clerk checks for the availability of the seat inthe train and if the seat is available then he makes entries regarding train name, train number, date ofjourney, boarding station, and destination. The passenger is the asked to pay the fair After makingpayment the passenger can collect the ticket from the clerk.2. CANCEL RESERVATIONThere may arise a case when the passenger wants to cancel his reservation For this he has to fill acancellation form providing all the details about the ticket reserved by him. The clerk then checks for theentries from the database and cancels the reservation finally returning the ticket amount with somededuction3. UPDATE TRAIN INFORMATION & REPORT GENERATIONOnly the Administrator has the right to make changes in train details(train name, train no. etc.). Thesystem should also be able to generate report when needed in the form of reservation charts, trainschedule charts etc.4. LOGINOnly the user with specified login id & password can get access to the system. This provides securityfrom unauthorized access.5. VIEW RESERVATION STATUS & TRAIN SCHEDULE

ODU2MTQ4/a/MjkwNjEwMTAyODU1/details Problem: 1 A company want to raise the salary of its employee. The raise rate is given as following: The raise rate is 20% of the salary if the employee have 15 years in work or more The raise rate is 10% of the salary if the employee have 7 years in work or more Otherwise, the raise rate is 5% of the salary. The new salary is computed by the formula: new salary=old salary x(1+ raise rate) Write a main program that prompts the user to enter n of employees then enter their salary and years in work of each of them. It displays the new salary for each employee and finally, it displays the average salaries of all employees after raising as shown in the following sample run. Sample run Enter the number of employees: 2 Enter the salary and the number of years of Employee 1: 1500 Enter the salary and the number of years of Employee 2. 800 16 8. The New Salary of Employee 1 is: 1800 The New Salary of Employee 2 is: 880 The average Salary of all employees is:…

If you have trouble reading the picture please let me know. 8. (a) Write behavioral Verilog code for a module called “Sort2” (pictured below) with three inputs s, a, b and two outputs x, y. The module’s function is also described below; in the function table, a “–” represents a don’t care. Also the function table has s, a as inputs, but the outputs x, y are expressed in terms of the third input b. In words, the “function table” to the left translates to the following: When s = 0, the smallest value among a and b goes to x and the other value goes to y. When s = 1, the largest value among a and b goes to x and the other value goes to y. (b) Structurally connect copies (or instantiations) of the module Sort2 to construct the module Bitonic with four inputs a0,a1,a2,a3 and four outputs z0,z1,z2,z3 shown below; each box in the figure below represents an instantiation of Sort2. Further, the inputs and outputs of the instantiations are located as in the figure above; namely, input to…
