How do I use STL in C++?

STL, or Standard Template Library, provides a set of C++ template classes to manage collections of data. What specific part of STL are you interested in?

Can you explain the different types of containers in STL?

Sure! STL includes several types of containers like vectors, lists, deques, sets, and maps. Each serves different purposes. Do you want details on a specific container?

Yes, what's the difference between a vector and a list?

A vector is a dynamic array that allows random access, while a list is a doubly linked list that allows efficient insertions and deletions. Would you like to see examples of how to use them?

Yes, please provide examples for both.

Here's a simple example for a vector:

#include <vector>
std::vector<int> vec = {1, 2, 3};

And for a list:

#include <list>
std::list<int> lst = {1, 2, 3};
