Task 3: Research Ways to Prevent Social Engineering Does your company or school have procedures in place to help to prevent social engineering? If so, what are some of those procedures? Use the Internet to research procedures that other organizations use to prevent social engineers from gaining access to confidential information. List yo

Im just having some trouble using functions in visual basics. Could you please explain what Im doing wrong? I think it has to do with the calling of the function.

Public Class Form1
    Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
        Me.Close()

    End Sub

    Private Function Rsumation(ByVal intx As Integer) As Double
        intx = CInt(Txtinput.Text)
        If intx = 1 Then
            Return 1
        Else Return (intx + Rsumation(intx - 1))

        End If
    End Function

    Private Sub Button2_Click(sender As Object, e As EventArgs) Handles Button2.Click
        MessageBox.Show(CStr(Rsumation(CInt(Txtinput.Text)).ToString("N2")))
    End Sub

End Class

convert -44 to 8-bit sign-magnitude, 1's complement, 2's complement and excess-127.

Please be careful and explain all the steps and details.

In the RSA cryptosystem, Alice’s public key (N, e) is available to everyone. Suppose that her private key d is compromised and becomes known to Eve. Show that if e = 3 (a common choice) then Eve can efficiently factor N.

Explain how to create different indices: primary index, secondary index, dense index, sparse index, respectively. Using above relation, you can either describe based on the definition of the indices or answer with the instance of the relation using some fake data/tuples.

C++ (cpp) PLEASE

Write a complete function (prototype and definition) that takes an integer array and the array dimensions as an input. The function should then square each value of the array in-place.

At the completion of the function return a Boolean which indicates the process has completed.

Design algorithms for the following operations for a binary tree T:

. preorderNext(p) : Return the position visited after p in a preorder traversal of T, or NULL if p is the last node visited.
. inorderNext(p) : Return the position visited after p in an inorder traversal of T, or NULL if p is the last node visited.
. postorderNext(p) : Return the position visited after p in a postorder traversal of T, or NULL if p is the last node visited.

C++

The Caesar cipher is one of the earliest known and simplest ciphers. It is a type of substitution cipher in which each letter in the plaintext is 'shifted' a certain number of places down the alphabet.

You are tasked to create an encryption program which takes a key word. The keyword will fill the first part of the shifted array. The remaining letters will fill the end of the array. It should look like this:

Key=”TOY

You should have an interactive menu with the following options:

1 Enter Key word //takes new key word and re-aligns shifted array

2 Encrypt message//takes a message of 140 characters and encrypts message

3 Decrypt message//takes an encrypted massage of 140 characters and decrypts it

4 Quit//exits program;

A couple tips:

Use the copy function from the <cstring> library not the <algorithm> library. If you use the algorithm library you need to make a change in visual studios precompiler settings or you will get an error. You cannot assign arrays using the ‘=’ operator; only individual indices of the array can be assigned this way.

Take one case or the other for input. All Caps or all lowercase. You can use “toupper(<char>)” to set all letters to upper case: http://cpp.sh/7gwx

/* toupper example */

#include <stdio.h>

#include <iostream>

#include <ctype.h>//for toupper

using namespace std;

int main ()

{

int i=0;

char str[]="Test String.\n";

char c;

while (str[i])

{

    c=str[i];

    str[i]=toupper(c);

    i++;

}

std::cout<<str<<endl;

return EXIT_SUCCESS;

}

When encrypting/decrypting, don’t change characters that are not in your Array set like punctuation and spaces
