What are the differences between std::array and std::list in C++?

What are the differences between std::array and std::list in C++?

std::array is a fixed-size array that provides fast access to elements, while std::list is a doubly linked list that allows dynamic size and efficient insertions/deletions.

When should I use std::array instead of std::list?

Use std::array when you know the size at compile time and need fast access. Use std::list for frequent insertions and deletions.

Are there any performance considerations I should be aware of?

Yes, std::array has better cache performance due to contiguous memory allocation, while std::list has overhead from pointers.

Can I convert between std::array and std::list?

You can convert by iterating through the elements and inserting them into the other container, but it's not direct.
