What am I doing wrong with this code?

public class Student {
private String name;
private double gpa;

// TODO: Define two private member fields

public Student() {
name = "Louie";
gpa = 1.0;
}

public void setName(String n) {

}

public String getName() {

}

public void setGPA(double gpa) {
this.gpa = gpa;
}

public double getGPA() {
return gpa;
}

public static void main(String[] args) {
Student student = new Student();
System.out.println(student.getName() + "/" + student.getGPA());

student.setName("Felix");
student.setGPA(3.7);
System.out.println(student.getName() + "/" + student.getGPA());
}
}

Answers

Answer 1

The issue with the code is in the setName() method. Instead of assigning the value of the n parameter to the name field, it is assigning the value of name to itself. To fix this issue, replace this.name = name; with this.name = n; in the setName() method. The corrected code should look like this:

public class Student {

private String name;

private double gpa;

public Student() {

name = "Louie";

gpa = 1.0;

}

public void setName(String n) {

this.name = n;

}

public String getName() {

return name;

}

public void setGPA(double gpa) {

this.gpa = gpa;

}

public double getGPA() {

return gpa;

}

public static void main(String[] args) {

Student student = new Student();

System.out.println(student.getName() + "/" + student.getGPA());

student.setName("Felix");

student.setGPA(3.7);

System.out.println(student.getName() + "/" + student.getGPA());

}

What is the explanation for the above response?

The above code defines a class called Student that has two private member fields, name and gpa, along with corresponding setter and getter methods to manipulate these fields.

It also includes a main method that creates an instance of the Student class, sets and gets the name and GPA of the student object, and prints out the values before and after modification.

def decimalToRep(integer, base):

# Define a lookup table of digits

digits = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ"

# Handle the special case of 0

if integer == 0:

return "0"

# Initialize an empty list to hold the digits in the new base

new_digits = []

# Convert the integer to the new base

while integer > 0:

remainder = integer % base

integer = integer // base

new_digits.append(digits[remainder])

# Reverse the list of new digits and join them into a string

new_digits.reverse()

new_string = "".join(new_digits)

return new_string

def main():

integer = int(input("Enter an integer to convert: "))

base = int(input("Enter the base to convert to: "))

print(decimalToRep(integer, base))

if __name__ == "__main__":

main()

Explanation:

This code prompts the user to enter an integer to convert and a base to convert it to using the input() function. It then calls the decimalToRep function with the input values and prints the resulting output. The if __name__ == "__main__" line at the bottom of the code ensures that the main function is only called when the script is run directly, not when it is imported as a module.

Here's an example input/output:

Enter an integer to convert: 123

Enter the base to convert to: 16

c++ BreakTheCode

In this task, you have to break the encapsulation.

Namely, the following code is loaded into the system:

class SecretClass {

private:

std::string token;

protected:

void SetTokenTo(SecretClass&another) {

another.token = token;

}

public:

SecretClass(const std::string& token) : token(token) {};

std::string GetToken() const {

return token;

}

};

void externalFunction(SecretClass& secret);

int main() {

SecretClass secret("FUTURE");
externalFunction(secret);
assert(secret.GetToken() == "CODE");

}

assert works like this. If the parenthesized expression is true, then nothing happens. If the parenthesized expression is false, your solution fails with an RE error.

Your task is to implement the function

void externalFunction(SecretClass& secret);

so that the expression secret.GetToken() == "CODE" at the end of main in the assert brackets is true.

In addition to this function, you can implement other auxiliary functions / classes if they help you solve the problem. All your code will be inserted into the system between the SecretClass class and the main function.

Send only the function code, necessary libraries and auxiliary functions to the system /
classes. Everything else will be connected automatically.

Answers

Explanation:

In order to break the encapsulation and modify the token value of the SecretClass instance, you can define a friend function within the SecretClass scope. This friend function will have direct access to the private and protected members of the class. Here's an example of how you can implement the externalFunction to modify the token value: #include <cassert>

#include <string>

class SecretClass {

private:

std::string token;

protected:

void SetTokenTo(SecretClass& another) {

another.token = token;

}

public:

SecretClass(const std::string& token) : token(token) {};

std::string GetToken() const {

return token;

}

friend void externalFunction(SecretClass& secret); // Declare externalFunction as a friend

};

void externalFunction(SecretClass& secret) {

secret.SetTokenTo(secret); // Modify the token value using SetTokenTo function

}

int main() {

SecretClass secret("FUTURE");

externalFunction(secret);

assert(secret.GetToken() == "CODE");

return 0;

}

By declaring externalFunction as a friend of SecretClass, we can directly call the SetTokenTo function inside externalFunction to modify the token value of the SecretClass instance.

When you run the code, it will break the encapsulation and modify the token value from "FUTURE" to "CODE", making the assertion secret.GetToken() == "CODE" true.

Use do while loop to find square root of odd number 1 to 200

Answers

Here's an example of using a do-while loop in Python to find the square root of odd numbers from 1 to 200:

```
import math

i = 1

# loop through odd numbers from 1 to 200
while i <= 200:
# check if number is odd
if i % 2 != 0:
# find square root using math.sqrt() function
sqrt_i = math.sqrt(i)
print("The square root of", i, "is", sqrt_i)
i += 1
```

This code uses a while loop to iterate through the odd numbers from 1 to 200. It checks if each number is odd using the modulus operator `%`. If the number is odd, it calculates the square root using the `math.sqrt()` function and prints the result. The loop then continues to the next odd number until it reaches 200.

Tessa and Rick plan to update these values with the number of guests their friends will bring with them to the party. Then, print the new dictionary.

This function should:

accept a list variable named “guest_list” through the function’s parameter;

add the contents of the list as keys to a new, blank dictionary;

assign each new key with the value 0;

print the new dictionary.

Exercise 21.2 You are the DBA for the VeryFine Toy Company and create a relation called Employees with fields ename, dept, and salary. For authorization reasons, you also define views EmployeeNames (with ename as the only attribute) and DeptInfo
with fields dept and avgsalary. The latter lists the average salary for each department. (10 points each)
1. Show the view definition statements for EmployeeNames and DeptInfo.
2. What privileges should be granted to a user who needs to know only average department salaries for the Toy and CS departments?
3. You want to authorize your secretary to fire people (you will probably tell him whom to fire, but you want to be able to delegate this task), to check on who is an employee, and to check on average department salaries. What privileges should you grant?
4. Continuing with the preceding scenario, you do not want your secretary to be able to look at the salaries of individuals. Does your answer to the previous question ensure this? Be specific: Can your secretary possibly find out salaries of some individuals (depending on the actual set of tuples), or can your secretary always find out the salary of any individual he wants to?
5. You want to give your secretary the authority to allow other people to read the EmployeeNames view. Show the appropriate command.
6. Your secretary defines two new views using the EmployeeNames view. The first is called AtoRNames and simply selects names that begin with a letter in the range A to R. The second is called HowManyNames and counts the number of names. You are so pleased with this achievement that you decide to give your secretary the right to insert tuples into the EmployeeNames view. Show the appropriate command and describe what privileges your secretary has after this command is executed.
7. Your secretary allows Todd to read the EmployeeNames relation and later quits. You then revoke the secretary’s privileges. What happens to Todd’s privileges?
8. Give an example of a view update on the preceding schema that cannot be implemented through updates to Employees.
9. You decide to go on an extended vacation and to make sure that emergencies can be handled, you want to authorize your boss Joe to read and modify the Employees relation and the EmployeeNames relation (and Joe must be able to delegate authority, of course, since he is too far up the management hierarchy to actually do any work). Show the appropriate SQL statements. Can Joe read the DeptInfo view?
10. After returning from your (wonderful) vacation, you see a note from Joe, indicating that he authorized his secretary Mike to read the Employees relation. You want to revoke Mike’s SELECT privilege on Employees, but you do not want to revoke the rights you gave to Joe, even temporarily. Can you do this in SQL?
11. Later you realize that Joe has been quite busy. He has defined a view called All-Names using the view EmployeeNames, defined another relation called StaffNames that he has access to (but you cannot access), and given his secretary Mike the right to read from the AllNames view. Mike has passed this right on to his friend Susan. You decide that, even at the cost of annoying Joe by revoking some of his privileges, you simply have to take away Mike and Susan’s rights to see your data. What REVOKE statement would you execute? What rights does Joe have on Employees after this statement is executed? What views are dropped as a consequence?

DeptInfo: CREATE VIEW DeptInfo AS SELECT dept, AVG(salary) as avgsalary FROM Employees GROUP BY dept;

2. The user should be granted SELECT privilege on the DeptInfo view.

3. For the secretary to fire people, check who is an employee, and check average department salaries, the following privileges should be granted:

• DELETE privilege on the Employees relation

• SELECT privilege on the Employees relation

• SELECT privilege on the DeptInfo view.

4. The previous answer does not ensure that the secretary cannot look at the salaries of individuals. If the secretary has SELECT privilege on the Employees relation, they could potentially query the salary column directly and see individual salaries. To prevent this, the secretary should only be granted SELECT privilege on the DeptInfo view, which provides average department salaries but not individual salaries.

5. To give the secretary authority to allow other people to read the EmployeeNames view, the following command should be used: GRANT SELECT ON EmployeeNames TO [username];

6. To give the secretary the right to insert tuples into the EmployeeNames view, the following command should be used: GRANT INSERT ON EmployeeNames TO [username]; After this command is executed, the secretary has INSERT, SELECT, and GRANT privileges on the EmployeeNames view.

7. If the secretary’s privileges are revoked, Todd’s privileges remain unchanged, since the GRANT statement was specifically for Todd and not dependent on the secretary’s privileges.

8. An example of a view update on this schema that cannot be implemented through updates to Employees is adding a new department to DeptInfo. This would require creating a new department in the Employees relation and calculating its average salary, which cannot be done through updates to existing tuples.

9. To authorize Joe to read and modify the Employees relation and the EmployeeNames relation, the following SQL statements should be used: GRANT SELECT, INSERT, UPDATE, DELETE ON Employees TO Joe WITH GRANT OPTION; GRANT SELECT, INSERT, UPDATE, DELETE ON EmployeeNames TO Joe WITH GRANT OPTION;

Joe can read the DeptInfo view if he has been granted SELECT privilege on it explicitly or if he has been granted SELECT privilege on the underlying Employees relation.

10. Yes, this can be done in SQL. To revoke Mike’s SELECT privilege on Employees without revoking Joe’s rights, the following command should be used: REVOKE SELECT ON Employees FROM Mike; This only revokes Mike’s SELECT privilege on Employees and does not affect Joe’s privileges.

11. The REVOKE statement that would be executed is: REVOKE SELECT ON EmployeeNames FROM Mike; This revokes Mike’s SELECT privilege on the EmployeeNames view. Joe still has the same privileges as before, but the All-Names view that he defined using the EmployeeNames view will no longer be accessible, since it depends on the revoked privilege. StaffNames is not affected since it is a separate relation that Joe has access to independently.
