C++: Set vs Map
An example of an AI chatbot conversation about C++ set and map data structures.
What is the difference 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 give me an example of when to use a set?
Use a set when you need to store unique items and perform operations like union or intersection.
And what about maps? When should I use them?
Maps are ideal when you need to associate values with unique keys, like a dictionary.
Are there performance differences between them?
Yes, sets and maps have different performance characteristics; sets are generally faster for lookups, while maps provide efficient key-value access.
