Why does the times method always start the block variable at 0 instead of 1?

hard📝 Conceptual Q10 of 15
Ruby - Loops and Iteration
Why does the times method always start the block variable at 0 instead of 1?
ABecause times method is designed for arrays only
BBecause it counts down from the integer to zero
CBecause the block variable is optional
DBecause Ruby uses zero-based counting for iterations
Step-by-Step Solution
Solution:
  1. Step 1: Understand Ruby iteration conventions

    Ruby, like many languages, uses zero-based counting for loops and iterations.
  2. Step 2: Explain times method behavior

    The times method yields values starting at 0 up to one less than the integer, following zero-based indexing.
  3. Final Answer:

    Because Ruby uses zero-based counting for iterations -> Option D
  4. Quick Check:

    Zero-based counting explains block variable start [OK]
Quick Trick: times block variable starts at 0 by design [OK]
Common Mistakes:
  • Thinking times counts down
  • Assuming block variable is optional
  • Confusing times with array methods
