Ruby - Basics and Runtime

Identify the issue in this Ruby code snippet:

def multiply(x, y)
  x * y
end

puts multiply(4)

AThe method multiply should use 'return' explicitly

BThe method multiply is missing one argument when called

CThe method multiply should be defined with default parameters

DThe method multiply cannot multiply integers

Step-by-Step Solution

Solution:

Step 1: Analyze method definition
The method multiply expects two arguments: x and y.
Step 2: Check method call
Calling multiply(4) provides only one argument, causing an argument error.
Step 3: Evaluate other options
Explicit return is optional in Ruby (B). Default parameters (C) are not required but could fix the error. The method multiply cannot multiply integers is incorrect.
Final Answer:
The method multiply is missing one argument when called -> Option B
Quick Check:
Method arguments must match definition [OK]

Quick Trick: Check method call arguments match definition [OK]
