Integer userNumber is read from input. Write a while loop that multiplies userNumber by 4, updating userNumber with the product, and outputs the updated userNumber, followed by a newline. The loop iterates until userNumber is greater than or equal to 40.Ex: If the input is 25, then the output is:

100

import java.util.Scanner;

public class ProductCalculator {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
int userNumber;

userNumber = scnr.nextInt();
while(userNumber >= 40){
userNumber = userNumber * 4;
System.out.println(userNumber);
}
Java. What am I doing wrong? It's not giving an output.

}
}

Answer: (A) Puts("hi");

Explanation:

 Puts() is the type function that uses the file handling in the programming language. It basically use to compose or write the function or line that displaying the output screen of the computer system.

The puts() function is the type of function which basically allow the user to read the characters or line include all the space until entering into the new character or line.

The declaration of the puts(0 function is as follows:

   int puts (char *STRING);

Answer:

a

Explanation:

Answer: (A) Prepared statement

Explanation:

 Prepared statement is basically used in the structured query language (SQL) statement which are basically execute multiple times in the python script.

The prepared statement is typically used in the SQL statement for update and queries. It is used to executed for the similar SQL statement and it has high efficiency.

It basically is in the form of template where the database compile and perform various query optimization.

Answer:

50 ms (milliseconds) will be taken in total to take the entire file by user.

Explanation:

In Computer networks, propagation delay is defined as the time in which a packet is sent from sender to receiver completely. It is computed by taking the ratio of link length and propagation speed.

We know that:

BDP(in bits) = total bandwidth (in bits/sec) * trip time(in sec)

Now according to given condition we have:

Bandwidth = R = 10 Mbps = 10,000,000 bps

BDP = 500,000 bits

For finding Propagation Delay:

Propagation Delay = BDP/ R

Propagation Delay = 500,000/10,000,000 sec

Propagation Delay = 0.05 sec

Converting in milliseconds:

Propagation Delay = 50 ms

Hence. the delay would be 0.05 seconds and in milliseconds they will be equal to 50 ms
