Answer:
// here is code in Java.
// package
import java.util.*;
// class definition
class Main
{
// method that return sum of two sale value
public static int Add(int euroSales,int asiaSales)
{
// return the sum
return euroSales+asiaSales;
}
//main method of the class
public static void main (String[] args) throws java.lang.Exception
{
try{
// variables
int euroSales=100;
int asiaSales=150;
int eurasiaSales;
// call the function
eurasiaSales=Add(euroSales,asiaSales);
// print the sum
System.out.println("total sale is:"+eurasiaSales);
}catch(Exception ex){
return;}
}
}
Explanation:
Declare and initialize two variables "euroSales=100" and "asiaSales=150". Declare another variable eurasiaSales. Call the method Add() with euroSales and asiaSales as parameter. This method will add both the value and return the sum.This sum will be assigned to variable eurasiaSales.Then print the sum.
Output:
total sale is:250
Answer:
// here is code in c.
#include <stdio.h>
// main function
int main()
{
// variable to store year
int year;
printf("enter year:");
// read the year
scanf("%d",&year);
// if year>=2101
if(year>=2101)
{
printf("Distant future");
}
//if year in 2001-2100
else if(year>=2001&&year<=2100)
{
printf("21st century");
}
//if year in 19011-2000
else if(year>=1901&&year<=2000)
{
printf("20th century");
}
// if year<=1900
else if(year<=1900)
{
printf("Long ago");
}
return 0;
}
Explanation:
Read the year from user.After this, check if year is greater or equal to 2101 then print "Distant future".If year is in between 2001-2100 then print "21st century".If year is in between 1901-2000 then print "20th century".Else if year is less or equal to 1900 then print "Long ago".
Output:
enter year:2018
21st century

Answer:
Security risk associated with sharing a printer are
- Printer Attacks
- Theft
- Breach of data
- Vulnerable Network
Explanation:
Printer Attacks
A network printer can be used for a DDoS attack.As printer are not very secured and are a weak link in network these can be easily exploited by the hackers for any kind of malicious activities and even lanching a DDoS attack.
DDoS attack is denial of service attack in which network is flooded with malicious traffic which cause it to choke and make it inaccessible for users.
Theft
Physical theft of document can be an issue.Anyone can just took printed pages from printer tray by any one.
Breach of Data
The documents which are printed are usually stored in printer cache for some time which can be accessed by any one connected to the network. Any document containing confidential information which are printed on network printer can fall in wrong hands.
Vulnerable Network
As mentioned a single unsecured network printer can pose great threat to entire network as it can provide a way into the network.
