Driver’s License Exam The local driver’s license office has asked you to create an application that grades the written portion of the driver’s license exam.

Explanation:

The exam has 20 multiple-choice questions. Here are the correct answers: 1. A 6. B 11. A 16. C 2. C 7. C 12. D 17. B 3. A 8. A 13. C 18. B 4. A 9. C 14. A 19. D 5. D 10. B 15. D 20. A Your program should store these correct answers in a list.
The program should read the student’s answers for each of the 20 questions from a text file and store the answers in another list.

import java.util.*;

class DriverExam{

char[] answer = new char[]{ 'B','D','A','A','C','A','B','A','C','D','B','C','D','A','D','C','C','B','D','A'};

int correct=0,inCorrect=0;

int[] missed = new int[20];

boolean passed(){

if(this.correct >= 15){

return true;

}

return false;

}

int totalCorrect(){

return this.correct;

}

int totalIncorrect(){

return this.inCorrect;

}

int[] questionsMissed(){

return this.missed;

}

public class Main

{

public static void main(String[] args) {

Scanner in = new Scanner(System.in);

System.out.println("Input : A,B,C,D");

System.out.println("Note : Any other inputs will result in skipping that question");

DriverExam exam = new DriverExam();

int i,missedIndex=0;

for(i=0;i<20;i++){

System.out.print("Answer "+(i+1)+" : ");

char check = in.next().charAt(0);

if(exam.answer[i]==check){

(exam.correct)++;

}

Consider the following recursive method, which is intended to return a String with any consecutive duplicate characters removed.

saul85 [17]

Answer:

D. return str.substring(0, 1) + removeDupChars(str.substring(1));

Explanation:

The logic here is following:

If the there are consecutive duplicate characters, return the removeDupChars method. The parameter of the removeDupChars method is a string, but the duplicate of the first character is removed from the string. The else-if part of the program does this job.

If the consecutive characters are not duplicated, return the first character of the string and the removeDupChars method. The parameter of the removeDupChars method is the rest of the string characters. The else part of the program does this job.

When the length of the str becomes one (or when the str is null), the program reaches its base and returns the str. The if part of the program does this job.

nalin [4]

Under the Solvent-Contaminated Wipes Rule (also known as the “Wipes Rule”), solvent-contaminated wipes sent for cleaning or disposal are conditionally excluded from hazardous waste regulation. As long as the solvent-contaminated wipes meet those conditions mentioned above, they are not considered hazardous waste Under the Resource Conservation and Recovery Act (RCRA),

Vesnalui [34]

Answer:

1: #include <iostream>

2: using namespace std;

3: int main()

4: {

5: int a,b,c,d;

6: cout<<"n1: ";

7: cin>>a;

8: cout<<"d1: ";

9: cin>>b;

10: cout<<"n2: ";

11: cin>>c;

12: cout<<"d2: ";

13: cin>>d;

14: int top = (a*d)+(b*c);

15: int bottom = b*d;

16: cout<<"Sum: "<<top<<"/"<<bottom<<"\n";

17: top = (a*d)-(b*c);

18: cout<<"Difference: "<<top<<"/"<<bottom<<"\n";

19: top = a*c;

20: cout<<"Product: "<<top<<"/"<<bottom<<"\n";

21: top = a*d;

22: bottom = b*c;

23: cout<<"Quotient: "<<top<<"/"<<bottom<<"\n";

24: return 0;

25: }

Explanation:

The Program is written in C++ programming language

The Program is left numbered

Line 5 was used for variable declaration.

Variables a,b represents the numerator and denominator of the first fraction

While variables c,d represent the numerator and denominator of the second fraction

Line 6 prints "n1" without the quotes which represents the numerator of the first fraction

Line 7 accepts input for the numerator of the first fraction.

Line 8 prints "d1" without the quotes which represents the denominator of the first fraction

Line 9 accepts input for the denominator of the first fraction.

Line 10 prints "n2" without the quotes which represents the numerator of the second fraction

Line 11 accepts input for the numerator of the second fraction.

Line 12 prints "d2" without the quotes which represents the denominator of the second fraction

Line 13 accepts input for the denominator of the second fraction.

Line 14 and 15 calculate the sum of the fractions which is then printed on line 16

Line 17 calculates the difference of the fractions which is then printed on line 18

Line 19 calculates the product of the fractions which is then printed on line 20

Line 21 and 22 calculates the quotient of the fractions which is then printed on line 23
