What is function overloading versus overriding?
PICTURE THIS: RAG CHATBOT
Simple meaning

WHY — OOP instead of guessing?
Why interviewers care about OOP:
contrast on OOP, not two memorised paragraphs.
the developer, then one case where picking wrong hurts.
Name the idea, why it exists, then one short example.
End with when you use it and one common pitfall.
STEPS — What happens step by step?
Before you speak the answer, walk the interviewer through these steps:
- 1Overloading is same name,
different parameters, resolved at compile time.
- 2Overriding is a derived
virtual method replacing the base, resolved at runtime.
- 3Mixing them without virtual
is a common trick question.
- 4Give an example
One tiny concrete case you can say aloud.
- 5Common mistake
What juniors usually get wrong.
- 6Close
When you pick this over the alternative.

Key takeaway
Overloading is same name, different parameters, resolved at compile time. Overriding is a derived virtual method replacing the base, resolved at runtime.
