Consider the following class:

Pachacha [2.7K]

Answer:

c.return Integer.compare(value, otherTemp.value)

Explanation:

The compare() method as the name implies compares two integer values. If they are equal it returns 0, if the first number is smaller it returns -1, and if the first number is greater it returns 1.

It is an Integer class method that is why you need to type Integer.compare() to call the function.

For this example, the parameters that will be compared are value, and otherTemp.value. The type of compareTo method is an integer, we need to return the result.

Scale-based classification for networks allows us to differentiate PANs, LANs, MANs, and WANs. Moreover, the structure of a netw

Nana76 [90]

Answer:

1. PANs uses Star Topology.

2. LAN uses four topology (Bus, Ring, Star and Tree).

3. MAN uses Star Topology.

4. WAN uses Bus topology.

Explanation:

1. PAN is the personnel area network, in which different personnel devices of a person are connect to each other with the help of the central computer with the help of Bluetooth, WiFi or some other medium. The central computer will work like a hub and all the devices are directly connected to the central PC. It is same as the ring topology where all the devices are connected to the central PC. So we can say that, PANs use star topology.

2. LAN is the local area network that has been established with in the premises of the organization. In this type of network, four typologies involve to complete the network connection. First is star topology, that is used to connect all the devices with the switches. Then Bus topology is used to connect all the switches with the single main cable. Ring topology is involved to connect all the switches with each other. Tree topology is used to connect different block if the organization in the form of branch to connect the central router or switch.

3. MAN is the Metropolitan Area Network which is comprise of different LANs. All the LANs are connected to the Router in the form of Star topology.

4. WAN is the wide area network. In WAN different MANs are connected to the network through single cable. This type of network uses Bus topology.

Write a program that grades arithmetic quizzes as follows: Ask the user how many questions are in the quiz. Ask the user to ente

kirill115 [55]

Answer:

The program in C++ is as follows:

#include <iostream>

using namespace std;

int main(){

int questions, answer;

cout<<"Questions: ";

cin>>questions;

int answerkey[questions];

cout<<"Enter answer keys: ";

for(int i = 0; i< questions; i++){

cin>>answerkey[i]; }

int correct = 0;

cout<<"Enter answers: ";

for(int i = 0; i< questions; i++){

cin>>answer;

if(answer == answerkey[i]){

correct++; } }

cout<<"Correct answers: "<<correct<<endl;

cout<<"Percentage correct : "<<(100 * correct)/questions<<"%";

return 0;

}

Explanation:

This declares the number of questions and the answers submitted to each equation

int questions, answer;

Prompt to get the number of questions

cout<<"Questions: ";

This gets input for the number of questions

cin>>questions;

This declares the answerkey as an array

int answerkey[questions];

Prompt to get the answer key

cout<<"Enter answer keys: ";

This iteration gets the answer key for each question

for(int i = 0; i< questions; i++){

cin>>answerkey[i]; }

This initializes the number of correct answers to 0

int correct = 0;

Prompt to get the enter the answers

cout<<"Enter answers: ";

This iterates through the answer keys

for(int i = 0; i< questions; i++){

This gets the answer to each question

cin>>answer;

This compares the answer to the answer key of the question

if(answer == answerkey[i]){

If they are the same, correct is incremented by 1

correct++; } }

Print the number of correct answers

cout<<"Correct answers: "<<correct<<endl;

Print the percentage of correct answers

cout<<"Percentage correct : "<<(100 * correct)/questions<<"%";
