C++ Set vs Map: What's the Difference?

What are the main differences between a Set and a Map in C++?

In C++, a Set is a collection of unique elements, while a Map is a collection of key-value pairs.

Can you explain how they store data?

Sets store only keys, ensuring uniqueness, while Maps store keys and associated values, allowing for quick lookups.

Which one is more efficient for searching?

Maps generally provide faster search times due to their key-value structure, especially for large datasets.

Are there any scenarios where I should prefer using a Set over a Map?

Yes, if you only need to store unique items without associated values, a Set is more appropriate and efficient.
