Draw the context level and 1st level DFD Software is to be developed to find the average marks of people in a class. The user interacts with the software via a special panel that lets him enter the required information. Initially, the software asks for number of students in the class by displaying a message on the panel screen. Once this information is entered, the software displays a message to enter names of students and marks. If negative marks or marks greater than 100 are entered, an error message is displayed. If marks are correctly entered the software calculates the average marks, stores them and also displays them on the screen.

Question#1 Scenario of web shop application: A supplier (with Supp-#) processes many purchase orders (with PO-#) and sells a number of products (with Prod-#). A product is sold by only one supplier. Each of the purchase orders that a supplier may process includes several products. The relationship between order and product is defined as "Line Item". A customer (with Cust-#) may place one or more purchase orders. A purchase order may be placed by only one customer. Design a complete ER diagram for the above verbal description of web shop application.
Change the order of the numbered Use Case Definition steps to correspond to the following problem definition: A college provides every incoming freshman with a gift card for a choice of two specialty restaurants within the cafeteria. Students should select one specialty restaurant they want. A program opens a window that displays each specialty restaurant one picture at a time when a student clicks the corresponding button. After making a decision, the student should click the Select Restaurant button. After selecting a restaurant, the student should exit the application.
PROGRAMMING LANGUAGE: C++ALSO PASTE SCREENSHOTS OF OUTPUTS You are required to create a simulation of an elevator system. There are 7 floors in a building. A user may enter the elevator and press the button of the destined floor. The simulation should display appropriate messages while moving towards the destined floor.
Hands-On Project 6-1 In this project you will program the actions of a sign-up form in which users must supply a user name, email address, and password for a new account. Passwords must be at least eight characters long and contain at least one letter and one number. As a validation test, the password must be entered twice to confirm that the user did not inadvertently mistype the password. If the password does not match the required pattern or if the two passwords are not identical, the password field should be flagged as invalid. A preview of the form in which the passwords are mismatched is shown in Figure 6-38. Figure 6-38 Completed Project 6-1 Do the following: Use your code editor to open the project06-01_txt.html and project06-01_txt.js files from the js06 ► project01 folder. Enter your name and the date in the comment section of each file and save them as project06-01.html and project06-01.js, respectively. Go to the project06-01.html file in your code editor and link the…
Joe’s Ristoranté is a small restaurant near a college campus. It serves both lunch and dinner from a standard menu. It also has a salad bar. Staff take orders by writing down the orders on an order pad. The orders are then taken to the kitchen where the food is prepared. When the food is ready, the staff are notified and deliver the food to the customer’s table. When the meal is finished, the staff provide customers with a bill, which has been prepared by hand. All sales must be paid by cash or credit card and entered into the cash register. Joe maintains one checking account for all sales receipts. Required: Create an REA diagram for Joe’s order-taking and cash receipts process, including all relationships.
Employee view attendance report The employee must be logged in to the system to perform this function. The employee selects the report period (range of dates: from - to). The employee selects "show report". Range of dates for the report must be maximum 3 months, so if the range is invalid, the system displays an error message. The system displays every working day in the report with the status of the employee in this day, which could be one of the following: on time, late, did not come. One actor? One use case name? One class ? Attributes for the class ? One relation between classes ?
Description: The program starts by asking the user to select either login (L) or sign up (S) feature. Once the user selects a feature, it asks him for (Card Number, then PIN) and after filling the required information for that feature, it shows the above menu for other features. Otherwise, it keeps asking for the required information. Each feature has to be designed using a separate function and it might be called by other functions including the main function. The description of the login feature, sign up feature, and the above features are given below: Sign up Feature – def create(): this feature allows new user to create an account and it saves his information in txt. The required information to be asked in this feature as follows: Card Number: user will enter a card number and should be four digits, each digit is unique and it should not be repeated in the 4-digits card number. This feature will keep running until the user enters the required number with same length and…
(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. (Hint: Calculate the dots showing on each die with the expression dots=(int)(6.0randomnumber+1), where the random number is between 0 and 1.)

Software Requirement Engineering Question: Draw a use case diagram for “Get a Cab” application ‘Get a Cab’ is a Smartphone application. It will search cabs for the passenger, provide them with security by reminding them about their luggage and it will also allow the user to inform the police with the help of a one-click button. This application facilitates the guardians to trace the location of their loved ones. It also lets passengers locate a driver at any instance to overcome all time related issues. If the passenger wants to avail the services of the same driver in future, he/she can add the driver to the favorite list, stored in the application. Write a detail use case for “Search a Cab” function. For searching a cab, the passenger would enter his/her source and destination information and the application would list down all the available cabs in a 1km radius. If application unable to find cab within 1km radius passenger can increase the radius up to 3 km. The passenger would…
ITP 100 Programming Logic & Design Project In this project, you will design a program to perform the following task: Design a program, the STAR Movie Rating App, which can be installed in a kiosk in theaters and patrons can immediately give their rating of a movie they’ve just seen. Each theater patron enters a value of 0, 1, 2, 3, or 4 indicating the number of stars that the patron awards to the App’s featured movie of the week. If a user enters a star value that does not fall in the correct range, the program will prompt the user continuously until a correct value is entered. The program executes continuously until a negative number is entered to quit. At the end of the program display: the number of ratings given the average star rating for the movie of the week the following message depending on the average rating. 3 or better – “Great movie choice!” 2 up to 3 – “Good movie choice!” 1 up to 2 – “Not a Good movie choice.” 0 up to 1 – “Bowling would have been a better…
Challenge task The distance a vehicle travels can be calculated as follows: distance = speed * time For example, if a vehicle starts a trip at 10 miles and travels 40 miles per hour for 4 hours, the distance traveled is 170 miles, the first 2 hours the distance=80+10=90, and the second one=160+10=170. Write a program which reads the speed of a vehicle (in miles per hour) and how many hours it has traveled. The program should then use a for loop to display the distance the vehicle has traveled for every 2 hours of that time period. 1 Roserio ףי Constraints None
