When multiple exceptions are caught in the same try statement and some of them are related through inheritance, does the order in which they are listed matter?

Answer: This can be explained s follows :-

Explanation: The approach in which services available in the network are used by the applications is called service oriented architecture. In such structure a business function is provided by each service that is independent of other services.

Object oriented programming is a programming paradigm. OOP can be used outside of that architecture or it can be apart of SOA as well .

Answer:   0,1,2,3

Explanation:

The array contains 4 elements that is 1,3,5,7.So the size of the array is 4.The indexing in an array starts from 0 means the element at 0 index is the first element in the array So 1 is at the index 0 and the index will increase by 1 as we move right of the array.So 3 is at the index 1 ,5 is at the index 2 and 7 is at the index 3.So the indices are 0,1,2,3.

Final answer:

Frames encapsulate packets in the context of networking, where the data link layer adds headers and trailers to the packet, forming a frame that is transmitted over the physical medium.

Explanation:

In the context of networking, frames encapsulate packets. When a packet, which is the unit of data at the network layer, is passed down to the data link layer to be prepared for physical transfer, it is encapsulated within a frame. The data link layer adds a header and sometimes a trailer to the packet, creating a frame. This frame includes not only the original packet's data but also additional information such as source and destination addresses, error-checking codes (like CRC), and control information necessary for establishing reliable links and ensuring data integrity over the physical medium.

The process can be thought of as an envelope (the frame) that carries a letter (the packet) inside it. Each network layer adds its own 'envelope' with specific information required for its operations. At the destination, these envelopes are removed in reverse order as data moves up through the layers until the original packet is delivered to the appropriate network layer application.

Answer:

two

Explanation:

A linked list is a data structure which stores the multiple-element with data type

and a pointer that stores the address of the next element.

A linked list is a series of nodes connecting each other by a pointer.

a node contains data and a pointer.

For build an array, two pointers are used:

the first pointer for specifies the starting node called head node.

and the second pointer is used to connect the other node to build the linked list.

Both are used to build the array if we lose the head node we cannot apply the operation because we do not know the starting node and we cannot traverse the whole linked list.

for example:

1->2->3->4->5

here, 1 is the head node and -> denote the link which makes by the second pointer.

Final answer:

To build a linked list, at least two pointers are needed: one for the head of the list and another within each node to point to the next node.

Explanation:

To build a linked list, you need two pointers. The first pointer typically points to the head of the list, which is the first node in the list. The second pointer, found within each node, points to the next node in the list. This setup allows the linked list to efficiently add and remove elements, by adjusting these pointers appropriately when nodes are inserted or deleted.

In contrast to arrays, linked lists do not use contiguous memory space and they allow for efficient insertions and deletions. They can grow and shrink during the execution of a program. Each node in a singly linked list generally contains the data part and the next pointer. However, in a doubly linked list, each node contains an additional pointer, known as the previous pointer, referencing the preceding node in the sequence to allow bidirectional traversal.

   public void setColor(String color){    //setter or mutator method

       this.color=color;    //set the color value equal to the parameter provided

   }

}

Answer: True

Explanation: Yes, there is a major impact of the decision maker's attitude on a risky situation. In risky situation if the decision maker is on side of taking non-risking decision then there would be less chances of severe outcome but if the decision maker tends to take risk then the situation can have any sort of impact good or bad as outcome. Therefore there is a huge impact of decision makers attitude.

Explanation:

Perfective maintenance usually is cost effective during the middle of the system.

Perfective maintenance usually is cost effective during the middle of the system.

Answer:

# In the new version of python is available the functions mean() an variance()

# In the module of statistics

i = 0 #Var to input the elements

l = [] #Var to store the elements on a list

while(i>0):

    print("In put a positive number to add in the list or negative to exit ")

    i = input()

    l.append(i)

    print("The mean of the all elements is: " + mean(l) )

    print("The variance of the all elements is: " + variance(i) )

Explanation:

At present, you can use in the news python's verison e.g. (python 3.7) the statistics module and use functions like mean(), variance(), stdev() and many others.

In the first step you create two variables, i to recieve the inputs of a loop and l to store all the elements recieved in the i variable. after that you pass as an argument the list that you stored before and get the mean() and variance() of the all elements in the list.

I hope it's help you.

Final answer:

The program asks the user to enter a number between 1 and 10 and uses a switch statement to convert it to a Roman numeral, with input validation to ensure the number is within the specified range.

Explanation:

Converting Numbers to Roman Numerals Using a Switch Statement

To write a program that asks for a number in the range of 1 through 10 and converts it to a Roman numeral, we can utilize a switch statement. Here is an example code in a programming language like C++ or Java:

#include <iostream>
using namespace std;
main() {
 int number;
 cout << "Enter a number in the range of 1 - 10: ";
 cin >> number;
 switch(number) {
   case 1: cout << 'I'; break;
   case 2: cout << 'II'; break;
   case 3: cout << 'III'; break;
   case 4: cout << 'IV'; break;
   case 5: cout << 'V'; break;
   case 6: cout << 'VI'; break;
   case 7: cout << 'VII'; break;
   case 8: cout << 'VIII'; break;
   case 9: cout << 'IX'; break;
   case 10: cout << 'X'; break;
   default: cout << "Error: invalid input.";
 }

 return 0;
}
This program will display a Roman numeral corresponding to the number entered by the user, ensuring that input validation is performed and only numbers between 1 and 10 are accepted.

Answer and Explanation:

Yes, the situation mentioned in the question is agreeable.

Diversity in the field source system is due to the presence of data elements present in the system which directly increases the complexity of the system.The data can be stored in one place in any amount at present time due to developed technology but there are chances of lapse and complexity.

The reason is the variety of types of data that is stored which makes it difficult to access the data related to every single element especially when the data storage is in a large amount. Individual data sources also don't show high dependency on. Thus the complexity arises.

// here i am writing C++ code

public class PricedApt extends RentalApt {

private double price;

RentalApt(firstname,price,b,lastname): PricedApt(firstname,b,lastname){

// As there is only one member in this class this means that every argument //coming to it is supposed to be passed to the parent class constructor.

// in c++ : operator is used to call the super class constructor

this.price = price;

Answer:

a. Unsigned integer  107

b. Signed magnitude integer  -43

c. One’s complement integer  -20

d. Two’s complement integer  21

e. ASCII character k

Explanation:

a) For unsigned integer,

   We put this value in representation of binary and put binary number in it.

   we will place 1, 2, 4, 8, 16, 32, 64, 128 ...(powers of two)

                         64  32  16  8  4  2  1

                           1     1    0   1   0   1   1        

The positions at 1 is present,we will add those numbers.In this                (64+32+8+2+1) =107 is there.

So,107 will be the representation.

b)For signed magnitude integer,

  The representation is just the same,but as signed integers the first bit represent the negative number.

                         64  32  16  8  4  2  1

                           1     1    0   1   0   1   1    

The first bit is for Negative(-),then we will add other number where 1 is present.In this (32+8+2+1)=43.We will add (-) due to signed integers.

So,-43 will be the representation.

c) For One's complement integer,

We will compliment the bits of binary number.At the place of 1 ,place 0 and at the place of 0,place 1.

                             1     1    0   1   0   1   1    

    Compliment   0   0    1   0  1   0   0    

Then,We put this value in representation of binary and put binary number in it, we will place 1, 2, 4, 8, 16, 32, 64, 128 ...(powers of two)                

                         64  32  16  8  4  2  1

                          0   0    1   0  1   0   0  

The positions at 1 is present,we will add those numbers.In this (16+8)=20    we will put negative at the starting because of the compliment

So, -20 will be the representation.

d)For Two's complement integer,

After compliment of bits At the place of 1 ,place 0 and at the place of 0,place 1.Then,we add 1 bit to the Least significant bit(Lsb).

                             1     1    0   1   0   1   1    

   Compliment     0   0    1   0  1   0   0    

 Add 1 to Lsb       0   0    1   0  1   0   0

                                                       +   1

   Number           0   0    1   0  1   0   1

Then,We put this value in representation of binary and put binary number in it, we will place 1, 2, 4, 8, 16, 32, 64, 128 ...(powers of two)                

                         64  32  16  8  4  2  1

                          0   0    1   0  1   0   1  

The positions at 1 is present,we will add those numbers.In this (16+8+1)=21

So,21 will be the representation.

e. For ASCII character,

First,convert it into decimal

  We multiply bits with 2^n,from ascending numbers to 0 to (n-1),and add them

           =   1 * 2^6 + 1*2^5 + 0* 2^4 + 1*2^3 + 0* 2^2 + 1*2^1 + 1* 2^0  

              =   64+32+8+2+1

                =  107

Then,we check in Ascii table 107 decimal number's position ,k is there.

So,k will be the representation.

Answer: True

Explanation:

Variable length instructions generally implemented by CISC processors use memory more efficiently than fixed length instruction of RISC processors sets because CISC supports array whereas RISC does not. Also CISC uses more complex addressing modes which consumes less memory cycles and the the program is also reduces. In Fixed length instruction in RISC processor the simple instructions has to be used a number of time which leads to more memory cycles.

Explanation:

A lot of math and time.

Answer:

nothing

Explanation:

Because the return type of the function is void. void means does not return any thing.

The syntax of the function:

type name( argument_1, argument_2,......)

{

  statement;

}

in the declaration the type define the return type of the function.

it can be int, float, double, char, void etc.

For example:

int count( int index);

the return type of above function is int. So, it return integer.

similarly,

void count(int index);

it return type is void. So, it does not return any thing.

  System.out.println("Temperature in Fahrenheit: "+fahrenheit+" °F");

 }else if(choice.equals("F")){

  System.out.println("Enter temperature in Fahrenheit: ");

  fahrenheit=input.nextDouble();

  celsius=(5*(fahrenheit-32))/9;

  System.out.println("Temperature in Celcius: "+celsius+" °C");

 }else{

  System.out.println("Wrong choice !!!");

 }

}

}

// writing c++ code...

// taking input

cout<< " Enter the floating point number : ";

cin>>fnumber;

// calculating the Fahrenheit temp

far_temp= (9.0/5.0) * fnumber +32;

cout<<" Fahrenheit = "<< far_temp;

Answer:

b- Cited,then refuted

Explanation:

Citation enhances persuasion of information sources.

Refutation means understanding the viewpoint of the opposition and then countering it by providing respective evidence  or by finding mistakes in the logic of the opposition's argument.

Answer: a) Two's complement number

Explanation: IMUL that is referred as signed multiply which performs the multiplication operation of two operands and IDIV is the referred as the signed division which performs the division between two operands. They perform their action on the two's complement number because of their signed behavior otherwise unsigned multiplication(MUL) and division(DIV) are  also present for other numbers.

Answer:

Constant

Explanation:

A default argument is a value provided in a function declaration that the compiler automatically assigns if the function caller does not provide a default value for the argument.

The value of a default argument must be constant.

The default value parameter must be a  constant for compiling. Compiler does not accept dynamically calculated value against optional parameter. The reason behind this it is not certain that the dynamic value you provide would offer some valid value.

Example:

#include<iostream>  

using namespace std;  

/*A function with default arguments, it can be called upto 4 arguments*/

int sumnum(int x, int y, int z=0, int w=0)  

{  

return (x + y + z + w);  

}  

int main()  //driver function

{  

cout << sumnum(10, 15) << endl;  

cout << sumnum(10, 15, 25) << endl;  

cout << sumnum(10, 15, 25, 30) << endl;  

return 0;  

}

Output

25

Recursive function with two parameters that return the number of uppercase letters in a String

public static int count(String str,int h)//Defining function

{

      if(str.charAt(0)>='A' && str.charAt(0)<='Z')//Checking the characters from A to Z

{

          h++; //incrementing the counter

          if(str.length()>=2){

              return count(str.substring(1),h);//recalling function

          }

      }

      if(str.length()>=2){

              return count(str.substring(1),h); //recalling function

      }

      return h;

  }

This is the recursive function with the name count of return type integer,having parameters str of string type and h of integer type.In this we are checking the characters at a particular position from A to Z.

Recursive function with one parameter that return the number of uppercase letters in a String

public static int count(String str)//Defining function

{

      if(str.charAt(0)>='A' && str.charAt(0)<='Z')//Checking the characters from A to Z

{

          count++; //incrementing the counter

          if(str.length()>=2){

              return count(str.substring(1));//recalling function

          }

      }

      if(str.length()>=2){

              return count(str.substring(1)); //recalling function

      }

      return count;

  }

This is the recursive function with the name count of return type integer,having parameters str of string type .In this we are checking the characters at a particular position from A to Z.

Java program that return the number of uppercase letters in a String

import java.util.*;

public class Myjava{

static int count =0;//Defining globally  

public static int count(String str,int h)//Defining function

{

      if(str.charAt(0)>='A' && str.charAt(0)<='Z')//Checking the characters from A to Z

{

          h++;

//incrementing the counter

          if(str.length()>=2){

              return count(str.substring(1),h);//recalling function

          }

      }

      if(str.length()>=2){

              return count(str.substring(1),h);

//recalling function

      }

      return h;

  }

  public static void main(String[] args)//driver function

  {

      System.out.println("Enter a string");//taking input

      Scanner scan = new Scanner(System.in);

      String s = scan.nextLine();

      int h =0;

      System.out.println("Counting the Uppercase letters: "+count(s,h));

  }

}

Output

Enter a string  WolFIE

Counting the Uppercase letters: 4

Final answer:

The question involves writing two methods to recursively count the number of uppercase letters in a String: a base method and a recursive helper method. The base method initiates the recursion with the string and its length, while the helper method implements the recursive logic, decrementing the count and checking for uppercase characters.

Explanation:

The question asks for the development of a recursive method to count the number of uppercase letters in a given string. This involves writing a base method count(String str) that initiates the recursion and a helper method count(String str, int high) which performs the actual recursive logic.

Method Definition

To achieve this, first, the base method needs to call the recursive helper method with the initial parameters - the string itself and the length of the string as the starting point. The recursive method will then decrement the count while checking for uppercase characters until it reaches the base case where the index (or high) is less than 0.

Example Implementation

public static int count(String str) {
   return count(str, str.length() - 1);
}

public static int count(String str, int high) {
   if (high < 0) {
       return 0;
   } else {
       int count = Character.isUpperCase(str.charAt(high)) ? 1 : 0;
       return count + count(str, high - 1);
   }
}

In this example, count("WolFIE") will indeed return 4, as it correctly identifies 'W', 'F', 'I', 'E' as uppercase letters.

Answer:

TRUE

Explanation:

In telecommunication and computing, there are different units of data storage. The most commonly used units are the bit and the byte.

A bit is the capacity of the system having only two states.

Whereas, the byte, also known as octet, is equal to eight bits. The unit symbol for Byte is B. In many computers, it is the smallest addressable unit of memory.

Therefore, the given statement is TRUE.

Answer:

Anti-Phising softwares in stand alone systems connected to  a centralized database.

Explanation:

In order to protect oneself from URL obfuscation attacks one should install anti-phising software in their systems which is a software to warn users when exposed to obfuscation attacks. These software when connected contains a centralized database maintained which warns users when they try to access an effected URL. So upon clicking such URL the users are warned in their screen and thus provided with an option to return to their previous page.

Anti-phising software come handy in preventing such attacks while accessing certain URLs in their mails also.

Answer:

function getLongestString(strings) {  

return strings.reduce( (acc, cur) => acc.length > cur.length ? acc : cur);

}

Explanation:

A reducer applies the same operation to each array element. In this case, the longest string is stored in the accumulator (acc), and is replaced only by the current element (cur) if the current element is longer than the accumulator.
