Write a while loop that assigns summedvalue with the sum of all values from 1 to usernum. assume usernum is always greater than or equal to 1. note: you may need to define additional variables.

Hi,

The program starts here


public class sumval
{ 
    public static void main(int usernum)
        {
              int summedvalue;
              int i=1;
                  while(i<=usernum)
                     {
                           summedvalue = summedvalue + 1;
                           i++;
                       }
                System.out.println("SUM OF VALUES IS ="+summedavalue);
         }
}

Wi-Fi Protected Access 2 (WPA2)

Explanation:

The Wi-Fi Protected Access 2 (WPA2) makes some alterations to the encryption algorithm that were used in WPA and WEP to what is known as the  Advanced Encryption Standard (AES). This is a 128-bit block cipher considered to be much more difficult to crack than the usual 128-bit TKIP wrapper. However, although WPA2 offers a much more tougher encryption standard, it is important to note that it is not hack proof.
