Writing in Java, write a program that prompts the user to input an integer and then outputs both the individual digits of the nu

larisa [96]

Answer:

//Here is code in java.

import java.util.*;

class Main

{

public static void main (String[] args) throws java.lang.Exception

{

try{

int in;

//scanner class object to read the input

Scanner scr=new Scanner(System.in);

// variable to keep running total

int total=0;

System.out.println("please enter an Integer:");

// read the input first time

in=scr.nextInt();

System.out.print("individual digits of "+in+" is ");

if(in<0)

{

in=-(in);

}

//call the function to print the digits of number

print_dig(in);

System.out.println();

//calculate the sum of all digits

do{

int r=in%10;

total=total+r;

in=in/10;

}while(in>0);

//print the sum

System.out.println("total of digits is: "+total);

}catch(Exception ex){

return;}

}

//recursive function to print the digits of number

public static void print_dig(int num)

{

if(num==0)

return;

else

{

print_dig(num/10);

System.out.print(num%10+" ");

}

Explanation:

Read a number with the help of object of scanner class.if the input is negative

then make it positive number before calling the function print_dig().call

the recursive method print_dig() with parameter "num".It will extract the digits

of the number and print then in the order. Then in the main method, calculate

sum of all the digits of number.

Output:

please enter an Integer:

3456

individual digits of 3456 is 3 4 5 6

total of digits is: 18

please enter an Integer:

-2345

individual digits of -2345 is 2 3 4 5

total of digits is: 14

A large population of ALOHA users manages to generate 50 requests/sec, including both originals and retransmissions. Time is slo

krok68 [10]

Answer:

The answer is below

Explanation:

Given that:

Frame transmission time (X) = 40 ms

Requests = 50 requests/sec, Therefore the arrival rate for frame (G) = 50 request * 40 ms = 2 request

a) Probability that there is success on the first attempt = $e^{-G}G^k$ but k = 0, therefore Probability that there is success on the first attempt = $e^{-G}=e^{-2}=0.135$

b) probability of exactly k collisions and then a success = P(collisions in k attempts) × P(success in k+1 attempt)

P(collisions in k attempts) = [1-Probability that there is success on the first attempt]^k = $[1-e^{-G}]^k=[1-0.135]^k=0.865^k$

P(success in k+1 attempt) = $e^{-G}=e^{-2}=0.135$

Probability of exactly k collisions and then a success = $0.865^k0.135$

c) Expected number of transmission attempts needed = probability of success in k transmission = $e^{G}=e^{2}=7.389$

A security system uses sensors at every door and window which will set off an alarm if any one of them is opened. There is also

jeka57 [31]

Well think of it like this lets say this wasn't and security system and it was a video game console and remote.
Now the console or keypad or the main components the power on or shut off the devices and the remote or sensors are the secondary parts but they are needed to help the console or keypad figure out what they are doing.

Match the steps with the actions that are involved when an internal host with IP address 192.168.10.10 attempts to send a packet

Anna35 [415]

Answer:

Following are the steps with actions that are involved in required to perform a packet transfer.

Explanation:

Step 1: The host sends a connection request to server which is at IP address 209.165.200.254
Step 2: R1 check the configuration of NAT to inquire weather the packet should be translated or not.
Step 3: If there is no entry found for translation of given IP address, It is assumed that the IP address 192.168.10.10 will be translated already.
Step 4: R1 selects a global address from the dynamic address pool that is available to it.
Step 5: R1 replaces the given IP address 192.168.10.10 with the translated inside global address.

i hope it will help you!
