We wish to implement a BigNumber class that represents nonnegative integers with up to 100 digits. To make this work, we will use an array of digits as the underlying representation. In particular, we will use an array of char, where each char represents an actual number from 0 to 9, not the ASCII characters '0' to '9'. That means when you implement the stream insertion operator you'll need to cast each array element to an int. So out << int(digits[i]) rather than out << digits[i].

Below it the code that will go in your BigNumber.h. You'll want to add the implementation file BigNumber.cpp where you implement all the prototypes in BigNumber.h. You'll also need to implement a Driver.cpp to with a main to test your functions.

class BigNumber

{

       friend ostream &operator<<(ostream &, const BigNumber &);     // stream insertion operator

// output the number as we would normally read it e.g. output 17 means the number seventeen.

private:

       char digits[100];  // to hold the digits with digits[i] representing the 10^i's place.

       int numDigits;  // number of digits in the number, e.g 5 has one digit but 45 has two. ZERO should have zero digits

public:

       BigNumber(int value = 0);  // default constructor.

int getNumDigits() const;         // return numDigits

       bool isZero() const;      // return true iff *this is equal to ZERO

       bool operator< (const BigNumber & c) const;     // less than

       bool operator>= (const BigNumber & c) const;    // greather than or equal

       bool operator<= (const BigNumber & c) const;    // less than or equal

       bool operator== (const BigNumber & c) const;    // equal

       bool operator!= (const BigNumber & c) const;    // not equal

};

//OUTPUT SHOULD BE AN INTEGER

UPLOAD THREE FILES: BigNumber.h and BigNumber.cpp and Driver.cpp. I should be able to load the three files in Visual Studio and everything will compile fine. I will also run your code with my driver so be sure your class will work correctly when tested extensively.

Your Driver.cpp will look something like this:

#include "BigNumber.h"

#include

using namespace std;

int main()

{

  BigNumber n(123);

  cout << n << endl;

// (etc.)

return 0;

}

The factorial of a nonnegative integer n is written n! (Pronounced “n factorial”) and is defined as follows: n! = n.(n-1). (n-2).……...1 (for values of n greater than 1) n!=1 (for n = 0 or 1)
For instance, 5! = 5.4.3.2.1 which is 120.
Write a Python program that reads a nonnegative integer n and calculates and prints its factorial. Your program should display a suitable error message if n entered as a negative integer.

1.       Given the algorithm to calculate the factorial of ‘n’. Mathematically analyze the given recursive algorithm to find out the time complexity of the algorithm.   

Algorithm F(n)

Describe what a stateful packet filter is as compared to a normal packet filter, especially the characteristics that a stateful packet filter has and that allow some protocols, e.g., FTP, to work, if it is configured to block unwanted incoming TCP initiations from the outside to a computer on the inside network.

Create two data documents containing a patientRecord

– one in XML and another in JSON

format

Your patientRecord must contain the following data:

-A patient’s name & ID number

-The date of his/her last appointment & the date of the last update

-The patient’s allergies – you must include 2 – one for a food allergy and one for a drug

allergy

-The patient’s preference – you must include 2 – one for a doctor and one for his/her

method of contact (which would have a value of text, phone, or email)

Describe what a buffer overflow attack is, especially the main purpose of the attack. During program execution, an input function is called to get a user's interactive input to the program. Describe what will happen to the return address kept in memory during the function call and the consequences if the user is an attacker performing a buffer overflow attack.

1) Given the list of integers 1, -2, 3, -6, 7, -8, 9, 10, -11, indexed from 1 to 9, the left-to-right linear scan algorithm (O(n) algorithm) will set as candidate start positions for a maximum contiguous sequence the elements at the index positions:

(a) 1,3,4,6

(b) 1,3,4,6,9

(c) 1,3,5,7

(d) none of the above

2)The Fibonacci sequence 1,1,2,3, ... can be generated iteratively by starting with the first two (0th and 1st) and generating every subsequent one by adding the previous two. In fact, the nth Fibonacci number can be generated by n − 1 additions for n ≥ 2. Thus we need 5 additions to generate the 6th Fibonacci number. However, a recursive program to generate the 6th Fibonacci number needs:

(a) 12 additions (b) 11 additions (c) 10 additions (d) None of the above

3)we can use a stack to check if a string made up of open, “(”, and closed, “)”, parentheses is balanced. Simulate this algorithm on the input string “((()))(())()” to determine if it is balanced or not. (this means you must explicitly write down the sequence of pushes and pops that the algorithm would generate

In Java, Write a JavaFX application that draws multiple circles using a rubberbanding technique. The circle size is determined by a mouse drag. Use the initial mouse press location as the fixed center point of the circle. Compute the distance between the current location of the mouse pointer and the center point to determine the current radius of the circle.Thank you and could you also show the finished product?

Write a program in C++ that declares an array of 100 integers named scores[]. Prompt the user for how many scores they want to enter. Then read in the specified number of ints and store them in the array. Then prompt the user for a passing grade. Use a for loop to go trough the array and count how many scores are passing. Print the count of how many passing scores, and also print a double that is the percent of scores that were passing. Note that although the scores array is allocated to store 100 ints,only the number of scores specified by the user are actually stored, so generally only part of the array storage capacity is used.

Intro into C++

Suppose we perform a sequence of n operations on a data structure in which the ith operation costs logi if
i is an exact power of 2, and 1 otherwise. Use two different methods to determine the amortized cost per
operation.

Using the object-oriented programming principles, write a currency exchange converter in Java. You should also use 3 different classes it could be currency1 and currency2 and currencytest, and set() and get() method and tostring() method. A person will be presented with 3 currencies (i.e., USD, AED, MYR) that they can convert to/from AED Dirham. The program will allow the user to input the amount of Dirham or other currency to be converted. The Money changer will take AED50 commission if converted amount is equal or more than AED900, or it will take AED10 commission if the converted amount is less than that.

Your program should throw an error message if the user tries to convert an amount less than AED30.

Note: 1 AED=0.27 USD,  1 AED=1.14 MYR

Sample output:

Please enter your currency (USD, AED, or MYR only): USD

What currency do you want?: AED

How much you want to convert? : 1000

Thank you. The converted amount is AED3673.20. We will take AED50 commission, and you will get 3623.20.

Please enter your currency (USD, AED, or MYR only): USD

What currency do you want?: AED

How much you want to convert? : 100

Thank you. The converted amount is AED367.32.  We will take AED10 commission, and you will get 357.32.

Please enter your currency (USD, AED, or MYR only) : AED

What currency do you want?: USD

How much you want to convert? : 367.32

Thank you. The converted amount is USD100.  We will take AED10 commission, and you will get USD97.28.
