Complete Question:

In which type of hacking does the user block access from legitimate users without actually accessing the attacked system?

Group of answer choices

a. Denial of service

b. Web attack

c. Session hijacking

d. None of the above

Answer:

a. Denial of service

Explanation:

Denial of service (DOS) is a type of hacking in which the user (hacker) blocks access from legitimate users without actually accessing the attacked system.

It is a type of cyber attack in which the user (an attacker or hacker) makes a system or network inaccessible to the legitimate end users temporarily or indefinitely by flooding their system with unsolicited traffic and invalid authentication requests.

A denial of service is synonymous to a shop having a single entry point being crowded by a group of people seeking into entry into the shop, thereby preventing the legitimate customers (users) from exercising their franchise.

<em>Under a DOS attack, the system or network gets stuck while trying to locate the invalid return address that sent the authentication requests, thus disrupting and closing the connection. Some examples of a denial of service attack are ping of death, smurf attack, email bomb, ping flood, etc. </em>

Write a function that converts a string into an int. Assume the int is between 10 and 99. Do not use the atoi() or the stoi() fu

Liula [17]

Answer:

Written in C++

#include <iostream>

#include <sstream>

using namespace std;

int main() {

string num;

cout<<"Enter a number: ";

cin>>num;

stringstream sstream(num);

int convertnum = 0;

sstream >> convertnum;

cout << "Output: " << convertnum;

}

Explanation:

Without using atoi() or stoi(), we can make use of a string stream and this is explained as follows:

This line declares a string variable num

string num;

This line prompts user for input

cout<<"Enter a number: ";

This line gets user input

cin>>num;

This line declares a string stream variable, sstream

stringstream sstream(num);

This line declares and initializes the output variable, convertnum to 0

int convertnum = 0;

The stream is passed into the output variable, convertnum

sstream >> convertnum;

This line displays the output

cout << "Output: " << convertnum;

<em>Note that: if user enters a non integer character such as (alphabet, etc), only the integer part will be convert.</em>

<em>For instance,</em>

<em>40a will be outputted as 40</em>
