Answer:

//To facilitate user input, the Scanner class is imported

import java.util.Scanner;

//The Solution class is being defined

public class Solution {

   //The main method is declared here, marking the start of program execution

   public static void main(String args[]) {

       

       //A Scanner object named 'scan' is instantiated to gather user input

       Scanner scan = new Scanner(System.in);

       //User is prompted to specify the size of the array

       System.out.print("Enter the range of array: ");

       //The user input is stored in arraySize

       int arraySize = scan.nextInt();

       //Initialization of userArray with the size specified by arraySize

       int[] userArray = new int[arraySize];

       

       //A counter is initialized to track the number of elements entered in the array

       int count = 0;

       //The following while loop will continue until the user finishes inputting the elements of the array

       while (count < arraySize){

           System.out.print("Enter each element of the array: ");

           userArray[count] = scan.nextInt();

           count++;

       }

       

       //A blank line is outputted for better readability

       System.out.println();

       

       //A for loop iterates to print all elements of the array in a single line

       for(int i =0; i <userArray.length; i++){

           System.out.print(userArray[i] + " ");

       }

       

       //Another blank line is printed for clarity

       System.out.println();

       

       //A for loop is utilized to reverse the contents of the array

       for(int i=0; i<userArray.length/2; i++){

           int temp = userArray[i];

           userArray[i] = userArray[userArray.length -i -1];

           userArray[userArray.length -i -1] = temp;

       }

       

       //A for loop prints each element of the reversed array in one line

       for(int i =0; i <userArray.length; i++){

           System.out.print(userArray[i] + " ");

       }

     

   }

}

Explanation:

The program is annotated to provide a thorough explanation.

The for-loop responsible for reversing the array operates by splitting the array into two segments and swapping elements from the first segment with those from the second segment. During each loop, an element from the first segment is temporarily stored in temp variable, and then that element is replaced with the corresponding element from the second segment. Subsequently, the element from the second segment is updated with the value held in temp.

The correct option is c) abstract class A { abstract void unfinished(); }. In order for a class to be considered a legal abstract class, it must include the keyword 'abstract' designated before the class name, and additionally, the abstract functions must also incorporate the 'abstract' keyword alongside a void return type.

Answer:

In C++:

#include <iostream>

#include <string>

#include <sstream>

using namespace std;

int main(){

   string lname, fname, stringnum;    int num; string login, pwd;

   cout<<"Last Name: ";    cin>>lname;

   cout<<"First Name: ";    cin>>fname;

   cout<<"Four-digit integer: ";    cin>>num;

   stringnum = to_string(num).substr(0, 4);

   stringstream geek(stringnum);    geek>>num;

   num = num%100;

   pwd = to_string(num);

   if(lname.length()<5){ login = lname + fname.substr(0, 1);    }

   else{ login = lname.substr(0, 5) + fname.substr(0, 1);    }

   cout<<"Login Name: "<<login<<endl;

   cout<<"Password: "<<pwd<<endl;

   return 0;

}

Explanation:

This initializes all the required variables

   string lname, fname, stringnum;    int num;     string login, pwd;

This asks the user for their last name

   cout<<"Last Name: ";    cin>>lname;

This asks for the first name of the user

   cout<<"First Name: ";    cin>>fname;

This prompts for a four-digit number

   cout<<"Four-digit integer: ";    cin>>num;

This converts the number into a string and extracts the first four digits

   stringnum = to_string(num).substr(0, 4);

This changes the string back into an integer

   stringstream geek(stringnum);    geek>>num;

This extracts the last two digits of the four-digit number

   num = num%100;

This generates the user's password

  pwd = to_string(num);

This constructs the user's login name.

This block runs if the last name has fewer than five letters

   if(lname.length()<5){ login = lname + fname.substr(0, 1);    }

This block runs otherwise

   else{ login = lname.substr(0, 5) + fname.substr(0, 1);    }

This displays the login name

   cout<<"Login Name: "<<login<<endl;

This displays the password

   cout<<"Password: "<<pwd<<endl;
