Collections vs Arrays in C++

What are the main differences between collections and arrays in C++?

Arrays are fixed-size and store elements of the same type, while collections are dynamic and can store different types.

Can you give me examples of collections in C++?

Sure! Common collections in C++ include vectors, lists, and maps, which are part of the Standard Template Library (STL).

When should I use a collection instead of an array?

Use collections when you need dynamic sizing or when you want to store different data types. Arrays are better for fixed-size data.

Are there performance differences between using arrays and collections?

Yes, arrays generally have better performance for fixed-size data due to lower overhead, while collections offer flexibility at a slight performance cost.
