Answer:
The program to this question can be described as follows:
Program:
#include <iostream> //defining header file
using namespace std;
int main() //defining main method
{
int x; //defining integer variable
for(x=0;x<=100;x++) //defining loop to count value from 0 to 100
{
if(x%7==0) //check value is divisable by 7
{
cout<<x<<endl; //print value
}
}
return 0;
}
Output:
please find the attachment.
Explanation:
In the above code, an integer variable x is declared, which is used in the for loop, in this loop variable "x" starts from 0 and ends when the value of x is less than and equal to 100.
- Inside the loop an, if block is used that defines a condition that is (i%7==0), it will check, that the value is divided by 7.
- In this loop, a print method is used, that prints its values.
Answer:
A. DDoS Attacks
Explanation:
A zombie, in computer terminology, is a hacker, computer worm, trojan horse, or virus compromised internet connected computer, which can be remotely directed to perform malicious tasks

Botnets which are also known as "zombie army", are used by hackers mainly for spam and distributed-denial-of-service, DDoS, attacks
While a DoS attack involves one machine, while a DDoS attack consist of multiple computing devices and machines
A botherder is the originator of a botnet and common botnets include Mr Black. Pushdo, and cyclone
Boolean operators, it uses the word "and","or" and "not" with keywords to control the search. For example if you search for health and food, the search engine will give a narrow search focusing on the two keywords. Using "or" with keywords will give much broader results. Using a "not" will remove one keyword from the search, ex. windy not rainy will give results of the keyword windy only. An asterisk on the other hand, gives wider results with variations.
