Question

For this lab you will write a Java program that will run a simple math quiz. Your program will generate two random integers between 1 and 20 and then ask a series of math questions. Each question will be evaluated as to whether it is the right or wrong answer. In the end a final score should be reported for the user.

This is a sample transcript of what your program should do. Items in bold are user input and should not be put on the screen by your program.

Enter your name: Jeremy
Welcome Jeremy! Please answer the following questions:

4 + 6 = 10
Correct!

4 * 6 = 24
Correct!

4 / 6 = 1
Wrong!
The correct answer is 0

4 % 6 = 4
Correct!

You got 3 correct answers
That's 75.0%!

Your code will behave differently based on the random numbers it selects and the answers provided by the user. Here is a second possible execution of this code:

Enter your name: Bob
Welcome Bob! Please answer the following questions:

3 + 3 = 0
Wrong!
The correct answer is 6

3 * 3 = 6
Wrong!
The correct answer is 9

3 / 3 = 0
Wrong!
The correct answer is 1

3 % 3 = 1
Wrong!
The correct answer is 0

You got 0 correct answers
That's 0.0%!

Answer 1

A java program was used to run a simple math quiz. the program was used to generate two random integers between 1 and 20 and then ask a series of math questions

Step-by-step explanation:

Solution

THE CODE:

import java.util.Random;

import java.util.Scanner;

public class LabQuiz {

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.println("****Welcome to Quiz******");

System.out.print("Enter your name: ");

String name = in.next();

System.out.println("Welcome "+name+"! Please answer the following questions:");

int scoreCounter=0;

int a;

int b;

int response;

a=getRandomNum();

b=getRandomNum();

System.out.print(a+"+"+b+"=");

response = in.nextInt();

if(response==(a+b)){

scoreCounter++;

System.out.println("That is correct");

}

else

System.out.println("No, thats not the right answer, its::"+(a+b));

a=getRandomNum();

b=getRandomNum();

System.out.print(a+"*"+b+"=");

response = in.nextInt();

if(response==(a*b)){

scoreCounter++;

System.out.println("That is correct");

}

else

System.out.println("No, thats not the right answer, its::"+(a*b));

a=getRandomNum();

b=getRandomNum();

System.out.print(a+"/"+b+"=");

response = in.nextInt();

if(response==(a/b)){

scoreCounter++;

System.out.println("That is correct");

}

else

System.out.println("No, thats not the right answer, its::"+(a/b));

a=getRandomNum();

b=getRandomNum();

System.out.print(a+"%"+b+"=");

response = in.nextInt();

if(response==(a%b)){

scoreCounter++;

System.out.println("That is correct");

}

else

System.out.println("No, thats not the right answer, its::"+(a*b));

System.out.println("You got "+scoreCounter+" correct answers.");

System.out.println("Thats "+(scoreCounter*25)+"%");

in.close();

}

static int getRandomNum(){

Random rand = new Random();

int a;

a = rand.nextInt(20);

if(a==0)

a++;

return a;

}

}
