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 get_price.py with a function get_price() that takes a dictionary of fruits as an argument and returns the name o

yawa3891 [41]

Answer:

The program is as follows:

def get_price(fruits):

AllPrice = fruits.values()

value_iterator = iter(AllPrice)

mostExpensive = next(value_iterator)

for item in fruits:

if fruits[item]>=mostExpensive:

mostExpensive = fruits[item]

fruitName = item

print(fruitName)

fruits = {}

n = int(input("Number of Fruits: "))

for i in range(n):

name = input("Fruit name: ")

price = int(input("Fruit price: "))

fruits[name] = price

get_price(fruits)

Explanation:

This defines the get_price function

def get_price(fruits):

This gets all price in the dictionary fruit

AllPrice = fruits.values()

This passes the values to a value iterator

value_iterator = iter(AllPrice)

This initializes mostExpensive to the first price in the dictionary

mostExpensive = next(value_iterator)

This iterates through the elements of the dictionary

for item in fruits:

If current element is greater than or equals most expensive

if fruits[item]>=mostExpensive:

Set most expensive to the current element

mostExpensive = fruits[item]

Get the corresponding fruit name

fruitName = item

Print fruit name

print(fruitName)

The main begins here

This initializes the fruit dictionary

fruits = {}

This gets input for the number of fruits

n = int(input("Number of Fruits: "))

This is repeated for every inputs

for i in range(n):

Get fruit name

name = input("Fruit name: ")

Get fruit price

price = int(input("Fruit price: "))

Append name and price to dictionary

fruits[name] = price

Call the get_price function

get_price(fruits)
