Answer:
1. Option A: for loop is correct
2. Option B: while loop is correct
Explanation:
Two loops are used commonly. For and while
For is used when the number of iterations are already known and while is used when number of iterations is not known and the loop has to be terminated based on any condition.
<u>1. You are finding the batting average of 13 baseball players.
</u>
For loop will be used as the number of iterations is already known. The score of 13 players has to be used to calculate the average so there will be 13 iterations. Hence, for loop will be used.
<u>2. You are asking your users for the names of all the stores where they shopped to find their friend's birthday present. They will show they are done by entering the word "done."</u>
While loop will be used as the termination of loop depends on the input given by the user so the number of iterations are not already known.
Hence,
1. Option A: for loop is correct
2. Option B: while loop is correct
Answer:
The correct answer to the following question will be Option B (VPN concentrator).
Explanation:
- Virtual Private Network (VPN) is a virtual, limited-use network generated using protocol encryption and tunneling over physical, public network connections.
- A dedicated tool for managing VPN connections built over an untrusted network, such as the Internet, is called a VPN concentrator.
- It's a type of networking system that ensures secure VPN connections are established and messages are transmitted between VPN nodes.
Therefore, Option B is the right answer.
Answer:
// here is code in java.
// import package
import java.util.*;
// class definition
class Main
{
// main method of the class
public static void main (String[] args) throws java.lang.Exception
{
try{
// print the name
System.out.print("my name is Sam. ");
// print the major
System.out.print("my major is CS.");
}catch(Exception ex){
return;}
}
}
Explanation:
In java, System.out.print() will print the statement but didn't go to the next line.If there is another System.out.print(), then it will also print into the same line.So here first the System.out.print() will print the name and second will print the major in the same line.
Output:
my name is Sam. my major is CS.
