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<<"%";

04. Suppose a computer program needs to sort a list of student records in ascending order

34kurt

Answer:

D) ["Kathy Bones", "Jill Brewer", "Joe Schnook", "Tom Smith"]

Explanation:

The context of the problem explains a computer program that sorts names in "ascending order" (A to Z) since the ASCII table has capital A start a lower number and it increases from there to capital Z.

Notice how the attached file, which is a portion of the ASCII table, shows that letters after A are also higher in decimal value than the previous letter.

With this in mind, we know that all this program does is sort by last name alphabetical order. From there, just sort the given names using that same criteria, last name alphabetical order, and the correct answer is determined.

Please put "Brainliest" on my answer if it helped you out!
