C++ List vs Vector: Which One to Use?

What are the main differences between C++ lists and vectors?

C++ lists are implemented as doubly linked lists, while vectors are dynamic arrays. Lists allow for efficient insertions and deletions, whereas vectors provide faster access to elements.

When should I use a list instead of a vector?

Use a list when you need frequent insertions and deletions in the middle of the container. Vectors are better for random access and when you need to store elements contiguously.

Are there any performance considerations I should be aware of?

Yes, vectors have better cache performance due to contiguous memory allocation, while lists have overhead from pointers. Choose based on your specific use case.

Can you give an example of when to use each?

Sure! Use a vector for a dynamic array of items where you need fast access, like a list of scores. Use a list for a playlist where you frequently add or remove songs.
