UML - Unified Model Language

Explanation:

Use case diagram:

A use case diagram is used to tell how many ways a   user can interact with  a system. We use special   symbols and connectors to build use case   diagrams.  

We use  horizontal shaped ovals to represent use   cases, stick figures to represent actors, lines to   represent associations between use cases and  

actors, packages to put elements into  groups.  

Use case description:  

By the name itself, we can say that it is used to   describe the activities of user that  he can do with   the system and how the system responds to those.  Before use case diagram created, we need to write   a use case description.  

Class diagram:  

UML diagrams are of two types. They are,  

A class diagram comes under Structural UML   diagrams.

Classes are building blocks of an application that   uses OOPs concepts. Class diagrams are used to   represent classes, relationships, association,  

interface.  

Sequence diagram:  

A sequence diagram comes under  Behavioral UML   diagrams.It is used to tell the sequential order of   objects' interaction.We have many notations in this   diagram like actors, lifeline, create message, delete   message, lost message, found message etc. It is   used to tell how messages move between objects in   a system.  

Domain model :  

A domain model is a visual representation of real-  situation objects. In UML,  the Domain Model is   illustrated with a set of class diagrams

Answer: C) algorithm it uses

Explanation: The operation signature has the name of operation ,objects that it accepts and the value returned by the operation but it does not have algorithm that it uses.As algorithm defines all the steps that are to be used to find the result so signature operation does not include the whole algorithm that is to be used. The signature operation verifies the steps of the algorithm in way.

Answer:

The height of tallest possible red-black tree having 31 values is 10.

Explanation:

The height of tallest possible red-black tree = 2㏒₂(n+1)

here we have n=31 So substituting the value of n in the equation.

=2㏒₂(31+1)

=2㏒₂(32)

=2㏒₂(2⁵)                   since ㏒(aⁿ)=n㏒(a)  

=2x5㏒₂(2)

=10㏒₂(2)                   since ㏒ₙ(n)=1.

=10.

applets

Explanation:

Java applets are dynamic programs that can be embedded on a webpage and run on a web browser like internet explorer,firefox or google chrome. The code for applets is developed using java programming language and facilitates interesting and complex display entities to be included as part of the web page. HTML provides a special tag called <Applet> for providing details of the applet.

Answer:

import java.util.Scanner;

public class Miles {

public static void main(String[] args) {

   //initialization

       double Number_Miles;

       //print the message

       System.out.print("Enter the number of miles: ");

       Scanner scn1 = new Scanner(System.in);

       Number_Miles = scn1.nextDouble();  //read the input from user

       //calculate the laps

       double yourValue = Number_Miles/0.25;

       //display the output on the screen

       System.out.printf("%.2f", yourValue);

}

}  

Explanation:

First import the library Scanner than create the class and define the main function. In the main function, declare the variables.

print the message on the screen and then store the value enter by the user into the variable.

Scanner is a class that is used for reading the output. So, we make the object of the class Scanner and then object call the function nextDouble() which reads the input and store in the variable.

After that, calculate the number of laps by dividing the number of miles with the given one lap running track value (0.25 miles).

[tex]Number\,of\,laps = \frac{Number\,of\,miles}{0.25}[/tex]

the output is stored in the variable.

After that, print the value on the screen with 2 digits after the decimal point.

we can use "%.2f" in the printing function in java.

like System.out.printf("%.2f", output);

Answer:

def miles_to_laps(miles):

  return miles / 0.25

miles = 5.2

num_of_lap = miles_to_laps(miles)

print("Number of laps for %0.2f miles is %0.2f lap(s)" % (miles, num_of_lap))

Explanation:

Answer:

The answer to this question is Java,C++.

Explanation:

We can assign non static final variables a value with the declaration or in the constructor but this is not the case with c++ because we have to assign value during declaration and c++ equivalent of final is const keyword and there is sealed or readonly keywords in c# not final.If we do not assign value at the time of declaration the const variable will contain garbage value which cannot be changed afterwards.

Answer:

47 → 101111

14 → 1110

81 → 1010001

102 → 1100110

241 → 11110001

Explanation:

There are two ways to calculate binary equivalent of decimal values:

       e.g.

       For 102, we put 1 at 64. than 102[tex]-[/tex]64 = 38

                      then put 1 at 32, now 38 [tex]-[/tex] 32 = 6.

                      then put 1 at 4, now 6 [tex]-[/tex] 4 = 2.

                      then put 1 at 2, now 2[tex]-[/tex]2 = 0.

                      so put 0 at 1 and all other places except those where we put 1.

Answer: A method without body is called abstract method. A abstract method can be called from a non abstract  class or method provided it is inherited using a subclass.

Explanation:

An abstract method is a method which does not have a body, it just has opening and closing curly braces. A class having an abstract method is also declared as abstract class. We cannot make an object of the abstract class.

example : public abstract float multiply(float x, float y);

is an example of abstract method.

calling an abstract method from a non  abstract method is possible provided it is inherited by a non abstract subclass.

Final answer:

The statement is false; class objects can indeed be passed as parameters to functions and returned as function values in many object-oriented programming languages.

Explanation:

The statement that class objects cannot be passed as parameters to functions or returned as function values is false. In many programming languages, especially those that support Object-Oriented Programming (OOP), it is common to pass objects as arguments to functions or methods, and also to return them as function values. This is part of the encapsulation feature in OOP, where an object bundles data and methods that operate on that data, allowing the methods direct access to the object's data without necessarily passing them as individual parameters.

For example, consider a Python class named Book. You can create an instance of this class and pass it to a function:

def display_book_info(book):
   print(book.title)
   print(book.author)

my_book = Book("Pride and Prejudice", "Jane Austen")
display_book_info(my_book)

In this case, my_book, which is an object of the class Book, is being passed as a parameter to the function display_book_info.

Answer:

Segment registers

Explanation:

The initial purpose behind the segment registers was to enable a program to access many distinct (big) memory sections designed to be autonomous and part of a constant virtual store.

They don't have a processor-defined objective, but instead Operating system runs them for purpose. The GS register is used in Windows 64-bit to point to constructions defined by the operating scheme.   Operating system kernels usually use FS and GS to access thread-specific memory. In windows, thread-specific memory is managed using the GS register. To access cpu-specific memory, the linux kernel utilizes GS.

Answer:

13

Explanation:

First understand the meaning of ++x, it is a pre-increment operator.

it means, it increase the value first than assign to the variable.

For example:

x=10

then after executing  ++x, the value of x is 11.

it increase the value and assign to x.

In the question:

The value of x is 10. After that, program moves to the if condition and check for condition (++x > 10) means (11 > 10) condition true.

then, 13 assign to x.

After that value of x is printed as 13.

Final answer:

The C++ code increments the variable x to 11 due to the pre-increment in the if statement, then changes x to 13 within the if block. Thus, the output of the code, when executed, is 13.

Explanation:

When the C++ code provided is executed, the statement int x=10; initializes the variable x with the value 10. The subsequent if statement checks if ++x > 10, where ++x is a pre-increment operation that increases x by 1 before the comparison. Since x is incremented to 11 before the comparison, the if block is executed, setting x to 13. The cout << x; statement then outputs the value of x, which at this point will be 13.

The characters << indicate that the value to the right is to be sent to the cout, which identifies the standard output stream. For cout to work, we need the inclusion of the iostream header file and the usage of the using namespace std; directive.

Answer:

system itself.

Explanation:

In Online Data Extraction data is extracted directly from the system itself.

A C++ program to determine if a given string is a palindrome involves converting the string to the same case, removing non-alphanumeric characters, and then checking if the string is equal to its reverse. Below is a sample code that performs these steps:

#include

#include

#include

#include

bool isPalindrome(const std::string& str) {

   std::string sanitized;

   for (char ch : str) {

       if (std::isalnum(ch))

           sanitized += std::tolower(ch);

   }

   std::string reversed = sanitized;

   std::reverse(reversed.begin(), reversed.end());

   return sanitized == reversed;

}

int main() {

   std::string input;

   std::cout << "Enter a string to check if it is a palindrome: ";

   std::getline(std::cin, input);

   bool result = isPalindrome(input);

   if(result) {

       std::cout << "The string is a palindrome." << std::endl;

   } else {

       std::cout << "The string is not a palindrome." << std::endl;

   }

   return 0;

}

In the above program, the function isPalindrome takes a string and creates a sanitized copy by iterating over each character, checking if it is alphanumeric (ignoring spaces and punctuation), and converting it to lowercase. After constructing the sanitized string, it creates a reversed version and compares the two. The main function reads a string from the user, calls the isPalindrome function, and outputs the result.
