Select a software package/electronic device that you know well. It can be from any domain (work related, entertainment, desktop,

etc.). For that application: 1. List and describe three tasks that it allows the user to perform, in order of importance. 2. List three aspects of the interface (dialogue style, screen organization, button layout, command structure, etc.) that you feel are well designed, one that you don't (more if you feel appropriate or applicable). Back up each choice using the design theories, principles, or guidelines discussed in class. For the aspect you feel is not well designed, suggest an alternative. 3. Analyze one of the major functions it performs and derive a requirements specification for it one task that it lets the user accomplish, i.e., a document describing what the software was designed to do, but not how it does it. Then suggest at least one alternative designs for part of the interface based on this requirements specification.

A software package that you know well is Opera Mini.

<h3>List and describe three tasks that it allows the user to perform, in order of importance.</h3>

A  software package is a term that connote a kind of multiple applications that can be also called code modules that functions together to meet a lot of goals as well as objectives. One of the most famous examples is the Microsoft Office package, opera mini, etc.

The task of opera mini are:

  • An AI-powered news aggregator,
  • Helps gives personalized news
  • A  private browsing

The three aspects of the interface  that are well designed are:

  • Its intuitiveness
  • Its Prevention
  • Its Graphical User Interface Design

Hence, A software package that you know well is Opera Mini.

algol13

The <u>camera, projector</u>, invented by the Lumiere brothers in Paris included a <u>phonograph</u>.

  • camera, projector, phonograph

<u>Explanation:</u>

Lumiere brothers, French designers and pioneer producers of photographic gear who formulated the early movie camera and projector called the Cinématographe. A cinematograph is a movie film camera, which likewise fills in as a film projector and printer.

The key development at the core of the Cinématographe was the instrument through which film was moved through the camera. It shows moving pictures on a screen. Which goes rapidly enough, an image replaces another too rapidly for the eye to see the change, along these lines shaping a moving picture.

5 QUESTIONS, BRAINLIEST, PLEASE ANSWER
lara [203]

Answer:

1. Input() is the correct answer

2.Most programming languages have a data type called a string, which is used for data values that are made up of ordered sequences of characters, such as "hello world". A string can contain any sequence of characters, visible or invisible, and characters may be repeated. ... A string can be a constant or variable .

3.The int() function converts the specified value into an integer number.

4.CandyCost = int(input("How much is the candy?"))

5.int()

Question 2 In this question you are asked to calculate probabilties for the discrete uniform and exponential distribution. Make
sasho [114]

Answer:

Hi there! The question is asking to make changes to the H3_Q2.java program however there is no such program attached. Nevertheless, the requirements in the question can be addressed in a new H3_Q2.java program that i've listed below.

Explanation:

We can use the Scanner util in Java for prompting user input. The method nextInt() and nextDouble() allow only values of types "int" and "double" respectively. I have used the "switch" statement to direct the program based on user selection of menu item. The checks are printed with the "System.out.println" command and the program exits in case of error or invalid input. Finally, the calculation of probability simply requires you to replace the comment with the formula for the probability calculation based on the method chosen.

H3_Q2.java

import java.util.Scanner;

public class H3_Q2 {

 public static void main(String args[]) {

   // print main menu for user selection

   System.out.println("Please type 1 to select 'discrete uniform' or 2 to select 'exponential'");

   Scanner scan = new Scanner(System.in);

   int selection = scan.nextInt();

   switch(selection) {

     case 1:

       // discrete uniform

       System.out.println("Please enter a lower bound value a: ");

       int a = scan.nextInt();

       System.out.println("Please enter a upper bound value b: ");

       int b = scan.nextInt();

       System.out.println("Please enter a value x: ");

       int x = scan.nextInt();

       if (b <= a) {

         System.out.println("The upper bound value b should be greater than the lower bound value a");

         System.exit(0);

       }

       if (a > x) {

         System.out.println("The value x should be greater than the lower bound value b");

         System.exit(0);

       }

       if (b < x) {

         System.out.println("The value x should be greater than the lower bound value b");

         System.exit(0);

       }

       break;

     case 2:

       // exponential

       System.out.println("Please enter a lambda value for exponential: ");

       double lambda = scan.nextDouble();

       System.out.println("Please enter a value x: ");

       double d_x = scan.nextDouble();

       if (d_x <= 0.0) {

         System.out.println("The value x should be greater than 0");

         break;

       } else {

         // calculate P(X = x) and P(X ≤ x)

         // result = calculateExponential()

         System.out.println("The calculation for the exponential method given the lambda value " + lambda + " and the value of x " + d_x + " is: ");

       }

       break;

     default:

       System.out.println("Invalid input. Exiting..");

       break;

   }

 }

}
