easy📝 Syntax Q12 of 15
Step-by-Step Solution
Solution:
Step 1: Check method syntax without explicit return
def add(a, b) a + b end defines a method where the last line isa + b, which will be returned automatically.Step 2: Compare other options
def add(a, b) return a + b end uses explicit return (also correct but not asked). def add(a, b) puts a + b end prints the sum but returns nil. def add(a, b) a + b; nil end returns nil explicitly.Final Answer:
def add(a, b) a + b end -> Option BQuick Check:
Last line expression returned [OK]
Quick Trick: Last expression in method is returned without return keyword [OK]
Common Mistakes:
- Using puts instead of returning value
- Adding explicit nil at the end
- Confusing printing with returning
