[Solved] Identify the problem in this code snippet: def example yield yield(5) end example { |x| puts x } — Ans: No problem, code runs and prints twice | Ruby

Ruby - Blocks, Procs, and Lambdas

Identify the problem in this code snippet:

def example
  yield
  yield(5)
end

example { |x| puts x }

AError because first yield has no argument but block expects one

BSyntax error in yield calls

CNo problem, code runs and prints twice

DBlock ignores argument and prints nothing

Step-by-Step Solution

Solution:

Step 1: Analyze yield calls and block parameters
The first yield calls block with no argument, second with 5.
Step 2: Understand block parameter expectations
The block expects one parameter x. The first yield passes none, but Ruby assigns nil to x, so no error occurs.
Final Answer:
No problem, code runs and prints twice -> Option C
Quick Check:
Yield with missing args passes nil [OK]

Quick Trick: Yield arguments can be nil if missing [OK]
