Find the error in this Ruby code:
5.next(2)
ANo error, code runs fine
Bnext method does not take arguments
CSyntax error due to missing parentheses
Dnext is not a method for numbers
Step-by-Step Solution

  1. Step 1: Check the next method signature

    In Ruby, Integer#next does not accept arguments; it returns the next integer.

    Calling 5.next(2) passes an argument, causing an ArgumentError.

  3. Final Answer:

    next method does not take arguments -> Option B

  4. Quick Check:

    Integer#next takes no arguments = D [OK]
Quick Trick: Integer#next has no parameters, just call without args [OK]
Common Mistakes:
  • Assuming next can take a number to jump ahead
  • Thinking next is not a method for numbers
  • Ignoring method argument rules
