Write a program in a class CharacterFrequency that counts the number of times a digit appears in a telephone number. Create an array of size 10 that will hold the count for each digit from 0 to 9. Read a telephone number from the keyboard as a string. Examine each character in the phone number and increment the appropriate count in the array. Display the contents of the array.

Assignment-5

Problem 1: In check-writing systems, it’s crucial to prevent alteration of check amounts. One common security method requires that the amount be written in numbers and spelled out in words as well. Even if someone can alter the numerical amount of the check, it’s tough to change the amount in words. Create a dictionary that maps numbers to their corresponding word equivalents. Write a script that inputs a numeric check amount that’s less than 1000 and uses the dictionary to write the word equivalent of the amount. For example, the amount 112.43 should be written as:

ONE HUNDRED TWELVE AND 43/100

Problem 2: Standard telephone keypads contain the digits zero through nine. The numbers two through nine each have three letters associated with them, as shown in the following table:

Many people find it difficult to memorize phone numbers, so they use the correspondence between digits and letters to develop seven-letter words (or phrases) that correspond to their phone numbers. For example, a person whose telephone number is 686-2377 might use the correspondence indicated in the preceding table to develop the seven letter word “NUMBERS.” Every seven-letter word or phrase corresponds to exactly one seven-digit telephone number. A budding data science entrepreneur might like to reserve the phone number 244-3282 (“BIGDATA”).

Every seven-digit phone number without 0s or 1s corresponds to many different seven-letter words, but most of these words represent unrecognizable gibberish. A veterinarian with the phone number 738-2273 would be pleased to know that the number corresponds to the letters “PETCARE.”

Write a script that, given a seven-digit number, generates every possible seven-letter word combination corresponding to that number. There are 2,187 (37) such combinations. Avoid phone numbers with the digits 0 and 1 (to which no letters correspond). See if your phone number corresponds to meaningful words.

Problem 3: Write a program in a class CharacterFrequency that counts the number of times a digit appears in a telephone number. Your program should create an array of size 10 that will hold the count for each digit from 0 to 9. Read a telephone number from the keyboard as a string. Examine each character in the phone number and increment the appropriate count in the array. Display the contents of the array.

CYB 362 – Vulnerability Analysis Hands-on Assignment

Objective

The objective of this lab is to gain experience in vulnerability analysis.

Prerequisites

  1. Laptop with internet connectivity
  2. Virtual environment
  3. One metasploitable machine
  4. One Kali machine

Lab Setup

  1. Go to https://www.tenable.com/try and sign up for a nessus trial
  2. Go to the email you signed up with and copy the activation code to a note and click the download link
  3. Download the nessus version that will work on your kali box. (Nessus-x.x.x-debian_amd64.deb)
  4. Be sure you downloaded and installed the VirtualBox extension pack form https://www.virtualbox.org/wiki/Downloads
  5. Go to https://sourceforge.net/projects/metasploitable/files/latest/download and download metasploitable to your host machine
  6. Extract the files to a folder on your desktop
  7. In VirtualBox create a new machine
  8. Set the type to linux and the version to Debian 32bit
  9. Create a new virtual hard disk, VDI
  10. Ensure the disk is dynamically allocated

b) Under what circumstances does the investor make a profit?
c) Under what circumstances will the option be exercised?
d) Draw a diagram showing the variation of the investor’s profit with the stock price at the maturity of the option.
e) Sketch how the value of the option varies with the stock price three months out, one month out, and on maturity

Problem 2.
Traders can use multiple strategies when they are bullish on the stock of a company. Two examples are
(i) writing a put option and (ii) buying a call option. Let us assume the stock does not pay a dividend.
