// Below is Java code.
// Package import
import java.util.*; // class definition class Main { // class main method public static void main (String[] args) throws java.lang.Exception { try{ // variables final int CENTS_PER_POUND = 25; final int FLAT_FEE_CENTS = 75; // Creating Scanner object for input
Scanner sr=new Scanner(System.in); System.out.print("Enter the shipping weight:"); // input reading
int shipWeightPounds=sr.nextInt(); // cost calculation
int shipCostCents = (shipWeightPounds * CENTS_PER_POUND) + FLAT_FEE_CENTS; // output Weight
System.out.println("shipping Weight: " + shipWeightPounds); // output flat fee System.out.println("flat fee of shipping in cents: " + FLAT_FEE_CENTS); // output cents per pound System.out.println("Cents/pound for shipping: " + CENTS_PER_POUND); // output shipping cost
System.out.println("total cost of shipping in cents: " + shipCostCents); catch(Exception ex){ return;} } } // Explanation: Define two constants "CENTS_PER_POUND=25" and "FLAT_FEE_CENTS=75". Use a Scanner object to capture user input for weight. Calculate the shipping cost by multiplying the weight with cents per pound and adding the flat fee. Then, display each value.
Answer:
Port 3389 is designated for remote desktop access to graphical user interfaces.
The syntax for tracking ping traffic is " tcp.port eq 25 or icmp".
Explanation:
Wireshark serves as a network packet sniffer utilized for analyzing and troubleshooting packet transmission within a network.
The ping command is employed in networks to verify connectivity between two devices. It sends ICMP echo messages to an IP address and awaits their return if the connection exists. To filter ping traffic in Wireshark, the syntax " tcp.port eq 25 or icmp" is applied.
This port 3389 acts as a listening port for the Microsoft proprietary remote desktop protocol, allowing remote connections to graphical interfaces of systems running the RDP server.
Answer:
#include <iostream>
using namespace std;
class Digits
{
public:
int num;
int read() //method to read num from user
{
cout<<"Enter number(>0)\n";
cin>>num;
return num;
}
int digit_count(int num) //method to count number of digits of num
{
int count=0;
while(num>0) //loop till num>0
{
num/=10;
count++; //counter which counts number of digits
}
return count;
}
int countDigits(int num) //method to return remainder
{
int c=digit_count(num); //calls method inside method
return num%c;
}
};
int main()
{
Digits d; //object of class Digits is created
int number=d.read(); //num is read from user
cout<<"\nRemainder is: "<<d.countDigits(number); //used to find remainder
return 0;
}
Output:
Enter number(>0)
343
Remainder is: 1
Explanation:
The program has a logical error that needs rectification. A correctly structured program calculates the remainder when a number is divided by the count of its digits. A class named Digits is created, consisting of the public variable 'num' and methods for reading input, counting digits, and calculating the remainder.
- read() - This function asks the user to enter the value for 'num' and returns it.
- digit_count() - This function accepts an integer and counts how many digits it has, incrementing a counter until 'num' is less than or equal to 0. It ultimately returns the digit count.
- countDigits() - This function takes an integer and delivers the remainder from dividing that number by its digit count. The digit count is computed using the 'digit_count()' method.
Finally, in the main function, a Digits object is instantiated, and its methods are utilized to produce an output.
Response:
No.
Clarification:
Since there are 5 vowels, at least 3 bits are necessary to represent them all. Utilizing 2 bits yields 2²=4 combinations, which isn’t enough. However, using 3 bits provides 2³=8 combinations, sufficiently covering the 5 vowels.
