easy📝 Syntax Q12 of 15

Ruby - Methods

Adef add(a, b) a + b end

Bdef add(a, b) return a + b puts 'done' end

Cdef add(a, b) puts a + b end

Ddef add(a, b) a + b; return end

Step-by-Step Solution

Solution:

Step 1: Check each method for implicit return usage
def add(a, b) a + b end returns the last expression a + b implicitly without return.
Step 2: Analyze other options
def add(a, b) return a + b puts 'done' end uses explicit return, def add(a, b) puts a + b end returns nil because puts returns nil, def add(a, b) a + b; return end has return with no value, returning nil.
Final Answer:
def add(a, b) a + b end -> Option A
Quick Check:
Implicit return = last expression value [OK]

Quick Trick: Implicit return means last line's value is returned [OK]
