easy📝 Conceptual Q1 of 15
Ruby - Inheritance

In Ruby, what does the method lookup path determine when a method is called on an object?

AThe memory address where the method is stored
BThe list of all methods available to the object regardless of inheritance
CThe order in which Ruby searches modules and classes to find the method definition
DThe number of times a method has been called on the object
Step-by-Step Solution
Solution:

  1. Step 1: Understand method lookup

    When a method is called on an object, Ruby searches through the object's class and included modules in a specific order.

  2. Step 2: Identify the lookup path

    This order is called the method lookup chain or path, which determines where Ruby looks for the method definition.

  3. Final Answer:

    The order in which Ruby searches modules and classes to find the method definition -> Option C

  4. Quick Check:

    Method lookup chain defines search order [OK]
Quick Trick: Method lookup chain is the search order for methods [OK]
Common Mistakes:
  • Confusing method lookup chain with all available methods
  • Thinking it relates to memory or call counts
