Write a python program to read four numbers (representing the four octets of an IP) and print the next five IP addresses. Be sur

sdas [7]

Answer:

first_octet = int(input("Enter the first octet: "))

second_octet = int(input("Enter the second octet: "))

third_octet = int(input("Enter the third octet: "))

forth_octet = int(input("Enter the forth octet: "))

octet_start = forth_octet + 1

octet_end = forth_octet + 6

if (1 <= first_octet <= 255) and (0 <= second_octet <= 255) and (0 <= third_octet <= 255) and (0 <= forth_octet <= 255):

for ip in range(octet_start, octet_end):

forth_octet = forth_octet + 1

if forth_octet > 255:

forth_octet = (forth_octet % 255) - 1

third_octet = third_octet + 1

if third_octet > 255:

third_octet = (third_octet % 255) - 1

second_octet = second_octet + 1

if second_octet > 255:

second_octet = (second_octet % 255) - 1

first_octet = first_octet + 1

if first_octet > 255:

print("No more available IP!")

break

print(str(first_octet) + "." + str(second_octet) + "." + str(third_octet) + "." + str(forth_octet))

else:

print("Invalid input!")

Explanation:

- Ask the user for the octets

- Initialize the start and end points of the loop, since we will be printing next 5 IP range is set accordingly

- Check if the octets meet the restrictions

- Inside the loop, increase the forth octet by 1 on each iteration

- Check if octets reach the limit - 255, if they are greater than 255, calculate the mod and subtract 1. Then increase the previous octet by 1.

For example, if the input is: 1. 1. 20. 255, next ones will be:

1. 1. 21. 0

1. 1. 21. 1

1. 1. 21. 2

1. 1. 21. 3

1. 1. 21. 4

There is an exception for the first octet, if it reaches 255 and others also reach 255, this means there are no IP available.

- Print the result

Write the definition of a function named swapints that is passed two int reference parameters. The function returns nothing but

Alja [10]

Answer:

void swapints(int *j,int *k)//Function definition.

{

*j=*j+*k-(*k=*j); //value swapping.

}

swapints(&j,&k);//call the function.

Explanation:

The above function definition takes the address of j and k variables which is stored on the pointer variable j and k.
Then the pointer variable uses the j and k value for the above expression, and the user does not need to return the value of j and k.
But when the user prints the value of the j and k variable, then he gets the swapping value of the j and k variable.
The user needs to know that the "int j" is a normal variable, but "int *j" is a pointer variable that is used to take the address of j variable.

Prompt the user to input five pairs of numbers: A player's jersey number (0 - 99) and the player's rating (1 - 9). Store the jer

tiny-mole [99]

Answer:

import java.util.Scanner;
public class Main {
public static void main (String [] args) {
int jersey_num [] = new int[5];
int rating [] = new int[5];
Scanner inStream = new Scanner(System.in);
for(int i=0; i < 5; i++){
System.out.print("Enter player " + (i+1) + "'s jersey number:");
jersey_num[i] = inStream.nextInt();
System.out.print("Enter player " + (i+1) + "'s rating:");
rating[i] = inStream.nextInt();
}
System.out.println("ROSTER");
for(int j=0; j < 5; j++){
System.out.println("Player " + (j+1) + "-- Jersey number: " + jersey_num[j] + ", Rating: " + rating[j]);
}
}
}

Explanation:

The solution code is written in Java. Firstly create two array, jersey_num and rating, with int type. This is to hold the five pairs of numbers input by user (Line 6 -7).

Next, create a for loop that run for 5 iterations and in each iteration prompt user to input jersey number and rating (Line 11 -17). The input number and rating will be set to the array, jersey_num and rating, respectively.

Next, print the title "Roster" (Line 19).

Create another for loop to display the five input pair of values (Line 21 - 23).

A <u>LED display</u> is an output device that enable a machine operator to view the acc or pre vlaue of an insstruction without the use of a programming terminal

<h3>What is LED display device?</h3>

LED Display (light-emitting diode display) is a screen display technology that uses a panel of LEDs as the light source. Currently, a large number of electronic devices, both small and large, use LED display as a screen and as an interaction medium between the user and the system.

<h3>Where is LED display used?</h3>

An LED (Light-Emitting Diode) is a small cell or conductor that glows and becomes illuminated when a voltage is applied to it. The phrase 'LED display' is often used broadly to describe screens on a wide range of devices. This includes commercial and consumer technology such as TVs, mobile phones, and PC monitors.

Let A be a 2D list in Python containing randomly assigned values where its size is also randomly generated up to 10 rows and 10

lana [24]

Answer:

Rows and cols of matrix1 : 5 6

Rows and cols of matrix1 : 4 4

We can't multiply these two as matrices.

Rows and cols of matrix1 : 3 8

Rows and cols of matrix1 : 8 6

We can multiply these two as matrices.

Explanation:

Note: Check attachment for the code. Also note that "page (1/3), page (2/3) and page (3/3)" are not part of the code, it is only for numbering the pages.

So, the aim in this question is to check if we can multiply the two lists given above as matrices. So, check below for what we are are going to input as the Python3 program which is in the attached file.

Therefore, when we write the Python3 program and run it we are going to get an output which will read as the following;

Rows and cols of matrix1 : 5 6

Rows and cols of matrix1 : 4 4

We can't multiply these two as matrices.

Rows and cols of matrix1 : 3 8

Rows and cols of matrix1 : 8 6
