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

<em> cin>>answerkey[i]; }</em>

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<<"%";

For this programming assignment, you have to write a Java program that tests whether a given input string represents a Valid E-m

Step2247 [10]

Answer:

To check if the email address is correct it should have only one "@" symbol, we have to split the input string by this symbol. The code in java to achieve this is the following:

class Main {

public static void main(String[] args) {

String email = "[email protected]";

String[] email_split = email.split("@");

long count_a = email.chars().filter(ch -> ch == '@').count();

if(count_a == 1){

System.out.println("User name: "+email_split[0]);

System.out.println("Domain name: "+email_split[1]);

}else{

System.out.println("There is no valid email address.");

}

Explanation:

The explanation of the code is given below:

class Main {

public static void main(String[] args) {

String email = "[email protected]"; //input string to evaluate if is valid email

long count_a = email.chars().filter(ch -> ch == '@').count(); //Count how many times the symbol @ appears

if(count_a == 1){ //A valid email only contains one at

String[] email_split = email.split("@"); //separate the values using the at in an array

System.out.println("User name: "+email_split[0]); //the first element is the username

System.out.println("Domain name: "+email_split[1]); //the second element is the domain name

}else{

System.out.println("There is no valid email address."); //If there isn´t an at or are more than one then display a message saying the email is not valid

A television advertisement claiming that a product is "light-years ahead of its time" does not make sense because (a) it doesn’t

adell [148]

Answer:

B. It uses "Light-years" to talk about time, but a light-year is a unit of distance.

Explanation:

Light-Year is a term used in astronomy to describe the distance that light travels in a year. Informally, astronomers use the light year to describe distances between planets, stars, moons and other astronomical bodies.

Light-years are sometimes mistakenly thought of as units of time — because of the year — but they're actually units of distance, equal to about six trillion miles. In 1851, the light year was first used for defining distances by a German astronomer who compared it to a "hiking hour," or the distance a person can hike in one hour. The term can also figuratively mean "a long way:"
