Ruby - Variables and Data Types
Identify the problem in this Ruby code snippet:
num1 = 10
num2 = 3
result = num1 / num2.to_f
puts result
ASyntax error in method call
BError because to_f is not a method
COutputs 3 because num1 is integer
DNo problem, outputs 3.3333333333333335
Step-by-Step Solution
Solution:

  1. Step 1: Understand to_f method

    to_f converts integer to float, so num2.to_f is 3.0.

  2. Step 2: Division with float operand

    num1 (integer) divided by float 3.0 results in float division: 10 / 3.0 = 3.3333333333333335.

  3. Final Answer:

    No problem; outputs 3.3333333333333335. -> Option D

  4. Quick Check:

    to_f converts integer to float correctly [OK]
Quick Trick: Use to_f to get float division result [OK]
Common Mistakes:
  • Thinking to_f is invalid method
  • Expecting integer division result
  • Assuming syntax error
