05.04 Comparing Procedural And Oop - Quiz

Check your understanding

1. What is the main difference between procedural and object-oriented programming?

   • Procedural is faster than OOP
   • Procedural uses functions while OOP uses classes
   • Procedural organizes code as functions operating on data, while OOP bundles data and methods together { data-correct }
   • OOP is always better than procedural

2. Which programming approach would be best for a simple temperature conversion program?

   • Object-oriented programming
   • Procedural programming { data-correct }
   • Both are equally good
   • Neither approach works

3. Look at this code. What approach does it represent?

   def calculate_area(length, width):
       return length * width
   
   def calculate_perimeter(length, width):
       return 2 * (length + width)
   

   • Object-oriented programming
   • Procedural programming { data-correct }
   • Functional programming
   • Event-driven programming

4. When would object-oriented programming be the better choice?

   • For simple mathematical calculations
   • For modeling real-world entities with complex state { data-correct }
   • For processing a single list of data
   • For basic input/output operations

5. What is a key advantage of procedural programming?

   • Better code reuse through inheritance
   • Encapsulation of data
   • Simplicity and directness for straightforward problems { data-correct }
   • Polymorphism support

6. In object-oriented programming, what replaces global variables for storing data?

   • Function parameters
   • Object attributes { data-correct }
   • Return values
   • Local variables

7. Which scenario would benefit most from object-oriented programming?

   • Calculating the average of numbers in a list
   • A video game with players, enemies, and items { data-correct }
   • Converting text to uppercase
   • Finding the maximum value in an array

8. What is the first step when converting procedural code to object-oriented?

   • Create inheritance hierarchies
   • Add polymorphism
   • Identify data that belongs together { data-correct }
   • Write more functions

9. Which statement about trade-offs between paradigms is correct?

   • OOP is always more efficient than procedural
   • Procedural programming is always easier to maintain
   • OOP provides better modularity for complex systems { data-correct }
   • There are no trade-offs between paradigms

10. Look at this code structure. What principle does it demonstrate?

    class Student:
        def __init__(self, name):
            self.name = name
            self.grades = []
    
        def add_grade(self, grade):
            self.grades.append(grade)
    

    • Functions operating on separate data
    • Data and methods bundled together { data-correct }
    • Global variable usage
    • Procedural decomposition
