Answer: It depends, but it is definitely a networking attack.

Explanation:

After scanning for vulnerable ports, I could go in a number of different directions. I could initiate a DOS attack by flooding a vulnerable port with requests. I could also initiate a Man-in-the-Middle attack by intercepting their network traffic (usually through port 80(HTTP) if it's not encryped). Because of this, it is highly recommended to use a VPN, so hackers have a harder time getting your data

Answer:

public class ANot {

public static void main(String[] args) {

int numberOfSides = 20;

boolean isQuadrilateral;

if(numberOfSides==4){

isQuadrilateral = true;

System.out.println("The triangle is quadrilateral");

}

else{

isQuadrilateral=false;

System.out.println("The triangle is not quadrilateral");

}

Explanation:

Create and Initilize the int variable numberOfSides (You can also receive this from a user using the scanner class for example).
create a boolean variable isQuadrilateral
Use if and else statement to check if numberOfSides ==4 and assign true to isQuadrilateral else assign false

When you take action independent of direct instruction, you are showing _____.

ozzi

Answer:

Option A, initiative

Explanation:

Initiation is an art of performing an act or task by self motivation rather on command or instruction from anyone.

Insubordination is incorrect as here there is no mentioning of disobeying seniors or authority

Also, courage and power means having strength to perform any task. Here action is performed without any instruction and it in no sense signifies a brave deed.

Hence, option A is correct

Given the following function definition:

The question is incomplete! Complete question along with its step by step answer is provided below!

Question:

Given the following function definition:

void calc (int a, int& b)

{

int c;

c = a + 2;

a = a * 3;

b = c + a;

}

x = 1;

y = 2;

z = 3;

calc(x, y);

cout << x << " " << y << " " << z << endl;

What is the output of the following code fragment that invokes calc?

a. 1 2 3

b. 1 6 3

c. 3 6 3

d. 1 14 9

e. None of these

Answer:

b. 1 6 3

Explanation:

In the given problem we have a function void calc which takes two input arguments a and b and updates its values according to following equations

c = a + 2;

a = a * 3;

b = c + a;

Then we call this function calc(x,y) by providing test values of

int x = 1;

int y = 2;

int z = 3;

and the output returns the values of x, y and z

cout << x << " " << y << " " << z << endl;

Lets find out what is happening here!

When the program runs we provide x=a=1 and y=b=2

c=a+2=1+2=3

a=a*3=1*3=3

b=c+a=3+3=6

So the updated values of a=x=3 and b=y=6?

NO!

The updated values are a=x=1 and b=y=6

WHY?

There are two ways to pass values

1. Pass by values -> value cannot change (int a)

2. Pass by reference -> value can change (int& b)

Look at the function void calc (int a, int& b) ;

Here we are passing (int a) as a value and (int& b) as a reference, therefore x remains same x=1 and y gets changed to updated value y=6 and z remains same as z=3 since it wasnt used by function calc(x,y)

The right answer is:

b. 1 6 3

x=1, y=6, z=3
