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

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

Lists in C++ are implemented as doubly linked lists, while vectors are dynamic arrays. This affects their performance and usage.

Can you explain how memory allocation differs between them?

Sure! Vectors allocate memory in contiguous blocks, which can lead to faster access times. Lists, however, allocate memory for each element separately, which can be slower.

When should I use a list instead of a vector?

Use a list when you need frequent insertions and deletions from the middle of the collection, as lists handle these operations more efficiently.

Are there any specific scenarios where vectors are preferred?

Yes, vectors are preferred when you need random access to elements or when the size of the collection is known in advance, as they provide better performance in these cases.
