1. Which of the following is NOT an essential programming concept?

Variables

Operating systems

Data structures

Loops

2. Which of the following is a common debugging technique?

Using print statements to track variable values

Ignoring errors during runtime

Relying solely on the compiler’s warnings

Writing the entire program in one function

3. What does the "try-catch" mechanism in error handling do?

It logs errors automatically to an external system.

It eliminates the need for error handling in the code.

It prevents errors from occurring.

It allows developers to handle exceptions without crashing the program.

4. In Object-Oriented Programming (OOP), what is the primary purpose of a class?

To store data in a structured format.

To handle user input and output.

To define the blueprint for creating objects and their behaviors.

To compile the program into machine code.

5. Which of the following concepts is an example of inheritance in OOP?

A class that cannot be subclassed or extended.

A method that returns the same type of data as the input.

A class that inherits methods and properties from another class.

A function that operates on a single variable.

6. What is one key benefit of building reusable and modular code?

It limits the flexibility to extend the code in the future.

It makes the codebase more difficult to maintain.

It allows easier testing and debugging of isolated components.

It increases the complexity of the software unnecessarily.

7. Which OOP concept allows objects to have their own specific behaviors while sharing a common interface?

Encapsulation

Inheritance

Polymorphism

Abstraction

8. Which technique can be used to handle unexpected errors during runtime in a program?

Code refactoring

Manual memory management

Exception handling

Compile-time checking

9. When building reusable code, what is one important principle to follow?

Avoid using functions or methods with side effects.

Ensure the code tightly couples with other code.

Create code that depends on specific hardware configurations.

Always write the code in a single large function.

10. Which of the following is true about encapsulation in OOP?

It allows all classes to freely access each other's internal data.

It restricts direct access to an object's internal state and requires interaction through defined methods.

It ensures that a class has no methods or properties.

It refers to the method of combining multiple classes into one large class.
