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<<"%";

Write a program that asks the user to enter an object’s mass, then calls a // function to return the object's weigh in newtown.

lisov135 [29]

Answer:

import java.util.Scanner;

public class num8 {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.println("Enter the mass");

double mass = in.nextDouble();

double weight = calWeight(mass);

System.out.println("The weigth is "+weight);

}

static double calWeight(double mass){

double weight = mass*9.80665; // assume a = accelation due to gravity = 9.80665N

if(weight>500){

System.out.println("Too Heavy");

}

else if(weight<100){

System.out.println("Too Light");

}

return weight;

}

Explanation:

Using Java programming language
The main method is created to request and store a variable, mass in kilogram. The main method call calWeight() and passes the value for mass
A method calWeight() is created that calculates the weight in newtons (mass * 9.8).
The method checks if the weight is greater than 500 (prints too heavy) if less than 100(prints to light)
Returns the weight
