Answer:

Option D i.e., radiation is the correct answer.

Explanation:

When any person challenges the specific security system for the purpose of stealing the resources from the corporate security system then they unable to threaten the radiation because it is the electromagnetic waves that affect the body or skin of any human being and it can be generated by those devices that have high-voltage.

Write a copy assignment operator for CarCounter that assigns objToCopy.carCount to the new objects's carCount, then returns *thi

ollegr [7]

Answer:

Here is the copy assignment operator for CarCounter:

CarCounter& CarCounter::operator=(const CarCounter& objToCopy) {

carCount = objToCopy.carCount;

return *this; }

The syntax for copy assignment operator is:

ClassName& ClassName :: operator= ( ClassName& object_name)

In the above chunk of code class name Is CarCounter and object name is objToCopy.

Assignment operator = is called which assigns objToCopy.carCount to the new objects's carCount.

This operator basically is called when an object which is already initialized is assigned a new value from another current object.

Then return *this returns the reference to the calling object

Explanation:

The complete program is:

#include <iostream> //to use input output functions

using namespace std; //to access objects like cin cout

class CarCounter { //class name

public: // public member functions of class CarCounter

CarCounter(); //constructor of CarCounter

CarCounter& operator=(const CarCounter& objToCopy); //copy assignment operator for CarCounter

void SetCarCount(const int setVal) { //mutator method to set the car count value

carCount = setVal; } //set carCount so setVal

int GetCarCount() const { //accessor method to get carCount

return carCount; }

private: //private data member of class

int carCount; }; // private data field of CarCounter

CarCounter::CarCounter() { //constructor

carCount = 0; //intializes the value of carCount in constructor

return; }

// FIXME write copy assignment operator

CarCounter& CarCounter::operator=(const CarCounter& objToCopy){

/* copy assignment operator for CarCounter that assigns objToCopy.carCount to the new objects's carCount, then returns *this */

carCount = objToCopy.carCount;

return *this;}

int main() { //start of main() function

CarCounter frontParkingLot; // creates CarCounter object

CarCounter backParkingLot; // creates CarCounter object

frontParkingLot.SetCarCount(12); // calls SetCarCount method using object frontParkingLot to set the value of carCount to 12

backParkingLot = frontParkingLot; //assigns value of frontParkingLot to backParkingLot

cout << "Cars counted: " << backParkingLot.GetCarCount(); //calls accessor GetCarCount method to get the value of carCount and display it in output

return 0; }

The output of this program is:

Cars counted = 12

Which formula would you enter into C3, and then AutoFill into C4 through C6, to calculate the percent sales (Pct.) for the regio

inna [77]

Answer:

In C3, you would enter the formula:

=B3/$B$7%

Explanation:

Let's assume the first row is 1 and it contains the titles of the columns. For instance, the content of the cellss A1:C1 could be:

A1: Region

B1: Sales

C1: Percent Sales

Also, assume the second row is empty and the cells on the first column, A, contain the names of four regions. For instance, North, South, East, and West:

A3: North

A4: South

A5: East

A6: West

The cells B3:B6 contain the sales for the four regions. For instance:

B3: 200

B4: 300

B5: 100

B6: 400

Then, you must calculate the percent sales for every region, in the cells C3:C6.

That means, you must divide the sale of every region by the total of sales and multiply by 100.

To do that in the worksheet you do this:

1. Sum the sales for the regions:

In cell B7 introduce: =SUM(B3:B6)

2. Calculate the percent sale for the first region:

In cell C3 introduce: =B3/$B$7%

That means that the reference B3 is relative: when you copy that formula, the column (B) and the row (3) will change accordingly to the cell where you will copy it.

Thus, by using the Autofill into C4 through C6, the column wil remain unchanged (C) and the row will change to 4, 5, and 6, respectively.

The symbol $ used in $B$7 make the reference absolute. That means that they will not change. The symbol % makes that the result is multiplied by 100.

3. When you use Autofull into C4 through C6, you obtain:

C4: =B4/$B$7%

C5: =B5/$B$7%

C6: =B6/$B$7%

The ____________ protocol enables two users to establish a secret key using a public-key scheme based on discrete logarithms

strojnjashka [21]

The answer in the space provided is the Diffie-Hellman Key Exchange. This is entitled to be the first published key algorithm in which has a limit in which the exchange occurs in secret values and that its purpose was to enable two users to have an exchange of key in a secure manner in means of using it for a subsequent symmetric encryption in terms of messages.

Complete the program below that takes in one positive, odd, integer, n (at least 3), and prints a "diamond" shape of stars with

avanturin [10]

Answer:

n = int(input("Enter the n (positive odd integer): "))

for i in range(1, n+1, 2):

print(i*"*")

for i in range(n-2, 0, -2):

print(i*"*")

Explanation:

*The code is in Python.

Ask the user to enter the n

Create a for loop that iterates from 1 to n, incrementing by 2 in each iteration. Print the corresponding number of asterisks in each iteration

Create another for loop that iterates from n-2 to 1, decrementing by 2 in each iteration. Print the corresponding number of asterisks in each iteration

Write a function string middle(string str) that returns a string containing the middle character in str if the length of str is

Katen [24]

Answer:

function getMiddle(s) {

return s.length % 2 ? s.substr(s.length / 2, 1) : s.substr((s.length / 2) - 1, 2);

}

// I/O stuff

document.getElementById("submit").addEventListener("click", function() {

input = document.getElementById("input").value;

document.getElementById("output").innerHTML = getMiddle(input);

});

Explanation:

// >>> is an unsigned right shift bitwise operator. It's equivalent to division by 2, with truncation, as long as the length of the string does not exceed the size of an integer in Javascript.

// About the ~ operator, let's rather start with the expression n & 1. This will tell you whether an integer n is odd (it's similar to a logical and, but comparing all of the bits of two numbers). The expression returns 1 if an integer is odd. It returns 0 if an integer is even.

// If n & 1 is even, the expression returns 0.

// If n & 1 is odd, the expression returns 1.

// ~n & 1 inverts those two results, providing 0 if the length of the string is odd, and 1 if the length of the sting is even. The ~ operator inverts all of the bits in an integer, so 0 would become -1, 1 would become -2, and so on (the leading bit is always the sign).

// Then you add one, and you get 0+1 (1) characters if the length of the string is odd, or 1+1 (2) characters if the length of the string is even.
