What are complex data structures in STL?

Can you explain what complex data structures are in the Standard Template Library?

Sure! Complex data structures in STL include structures like vectors, lists, maps, and sets that allow for efficient data management.

How do vectors differ from lists in STL?

Vectors are dynamic arrays that allow random access, while lists are doubly linked lists that provide efficient insertions and deletions.

When should I use a map instead of a set?

Use a map when you need to associate keys with values, while a set is used for storing unique elements without any specific order.

Can you give an example of using a priority queue in STL?

Certainly! A priority queue in STL can be implemented using a vector or a deque, allowing you to efficiently manage elements based on their priority.
