What is the minimum length in hop by hop extension header in ipv6 ?

In this assignment, you are expected to rewrite the program from assignment7 using structs. That is, instead of using multiple arrays (one for each field, you need to create a single array of the datatype you should create as a struct).

So, write a C++ program (use struct and dynamic memory allocation) that reads N customer records from a text file (customers.txt) such as each record has 4 fields (pieces of information) as shown below:

Account Number (integer)

Customer full name (string)

Customer email (string)

Account Balance (double)

The program is expected to print the records in the format shown below, sorted in decreasing order based on the account balance:

Account Number : 1201077

Name                     : Jonathan I. Maletic

Email                     : [email protected]

Balance                   : 10,000.17

-------------------------------------

Note: The records stored in the following format (4 lines for each account). You need to create a text file that contains sample records as explained in class:

First Line is the account number

Second Line is full name

Third line is email

Forth line is the available balance

Important Note: You must create a struct called (Customer) with enough members (to hold record information) and use it to declare a dynamic array to store all the records (information) read from the file. Then sort the array and then print it. Use the example shared in class (see the slides) as a model for your program.

• Make sure your programs adhere to proper programming style (e.g., good identifiers, comments, etc.)

This is C++, please insert screenshot of output please.

Part1: Palindrome detector

Write a program that will test if some string is a palindrome

1. Ask the user to enter a string
2. Pass the string to a Boolean function that uses recursion to determine if something is a palindrome or not. The function should return true if the string is a palindrome and false if the string is not a palindrome.
3. Main displays the result ( if the string is a palindrome or not

Problem 1 (Ransom Note Problem) in python

A kidnapper kidnaps you and writes a ransom note. He does not write it by hand to avoid having his hand writing being recognized, so he uses a magazine to create a ransom note. We need to find out, given the ransom string and magazine string, is it possible to create a given ransom note. The kidnapper can use individual characters of words.

Here is how your program should work to simulate the ransom problem:

• your program should prompt the user to enter a long String to represent the magazine and another short String to represent the required ransom note.
• your program needs to check if the magazine string contains all required characters in equal or greater number present in the ransom note.
• your program should print true if it is possible to create the given ransom note from the given magazine, and print false otherwise.
• Break up your code into a set of well-defined functions. Each function should include a comment block that briefly describes it, its parameters and any return values. 


Example: If the magazine string is “programming problems are weird”

If the ransom note is: “no see” your program should print true as all the characters in “no see” exist in the magazine string.

If the ransom note is “no show” your program should print false as not all the characters in “no show” exist in the magazine string as you can see the character ‘h’ does not exist.

Can anyone just check my code and tell me why the program doesn't show the end date & stops at the date before the end date? Tell me how i can fix it.

Question:

Write a program compare.cpp that asks the user to input two dates (the beginning and the end of the interval). The program should check each day in the interval and report which basin had higher elevation on that day by printing “East” or “West”, or print “Equal” if both basins are at the same level.

My code:

#include

#include

#include

#include

using namespace std;

int main()

{

string date;

string starting_date;

string ending_date;

double eastSt;

double eastEl;

double westSt;

double westEl;

int dateRange=0;

cout<< "Enter the starting date" << endl;

cin>> starting_date;

cout<< "Enter the ending date" << endl;

cin>> ending_date;

ifstream fin("Current_Reservoir_Levels.tsv");

if (fin.fail())

{

cerr << "File cannot be opened for reading." << endl;

exit(1);

}

string junk;

getline(fin, junk);

while(fin >> date >> eastSt >> eastEl >> westSt >> westEl)

{

fin.ignore(INT_MAX, '\n');

if (date == starting_date)

{

dateRange = 1;

}

if (date == ending_date)

{

dateRange= 0;

}

if (dateRange == 1)

{

if(eastEl > westEl)

{

cout<< date << " "<< "East " <

}

else if (eastEl < westEl)

{

cout<< date << " " << "West" <

}

else if (eastEl == westEl )

{

cout<< date << " " << "Equal" <

}

}

}

return 0;

}

Instruction

This task is about using the Java Collections Framework to accomplish some basic textprocessing tasks. These questions involve choosing the right abstraction (Collection, Set, List, Queue, Deque, SortedSet, Map, or SortedMap) to efficiently accomplish the task at hand. The best way to do these is to read the question and then think about what type of Collection is best to use to solve it. There are only a few lines of code you need to write to solve each of them. Unless specified otherwise, sorted order refers to the natural sorted order on Strings, as defined by String.compareTo(s). Part 0 in the assignment is an example specification and solution.

1. Briefly explain the principle of least privilege and how it should be applied. 2. Explain what describes a truly secure password.

Summary

In this lab the completed program should print the numbers 0 through 10, along with their values multiplied by 2 and by 10. You should accomplish this using a for loop instead of a counter-controlled while loop.

Instructions

1. Write a for loop that uses the loop control variable to take on the values 0 through 10.
2. In the body of the loop, multiply the value of the loop control variable by 2 and by 10.
3. Execute the program. Is the output the same?

4. // NewMultiply.java - This program prints the numbers 0 through 10 along
   // with these values multiplied by 2 and by 10.
   // Input: None.
   // Output: Prints the numbers 0 through 10 along with their values multiplied by 2 and by 10.

   
   public class NewMultiply
   {
   public static void main(String args[])
   {
     
   String head1 = "Number: ";
   String head2 = "Multiplied by 2: ";
   String head3 = "Multiplied by 10: ";   
   int numberCounter; // Numbers 0 through 10.
   int byTen; // Stores the number multiplied by 10.
   int byTwo; // Stores the number multiplied by 2.
   final int NUM_LOOPS = 10; // Constant used to control loop.

   // This is the work done in the housekeeping() method
   System.out.println("0 through 10 multiplied by 2 and by 10" + "\n");

   // This is the work done in the detailLoop() method
   // Write for loop
   
   // This is the work done in the endOfJob() method
   System.exit(0);
   } // End of main() method.

   } // End of NewMultiply class.

Your code should contain a PHP function that, accepting the string of 1000 numbers in input, is able to:

1) Find the 5 adjacent numbers that multiplied together give the largest product.

2) Given the product from above, computes the sum of the factorial of each term of such product

Example, if the product is 5046, computes 5! + 0! + 4! + 6!

NOTE:

• If the file doesn't contain 1000 numbers or contains some characters in between, it should be discarded and the application should inform the user that the file is not format correctly.
• Add a tester function to check the behavior of your PHP function.
• Follow the guidelines discussed and showed in class to avoid losing points.

How would you reply to this discussion:

Cloud Computing is a way to store massive amounts of information on remote servers. Unlike saving information on your local hard drive or flash drive, cloud storage is almost like a magical place that keeps (so we hope) your information safe and secure. A couple of different cloud computing examples are.

1. Communication: these would be examples of Skype or WhatsApp. I have used both applications, though I haven't used skype in many years, I currently use WhatsApp daily,

2. Backup and Recovery: Large storage to save your information. I always like to say, It's somewhere in the cloud. Examples, Dropbox, Google Drive, and Amazon S3. Out of these three, I have only used Dropbox, this was used during my Web Design class.

3. Social Networking: We all know about social networking, we all may use them on a daily basis. Also, social networking is the most popular of cloud computing. Some examples are Facebook, LinkedIn and Instagram to name a few.

This week I actually learn a lot. Back in my computer help desk days, I remember building a computer by imaging. But it was different to see the different way to divide the disk space. Very interesting.
