How do I use STL containers in C++?

STL containers are part of the Standard Template Library in C++. They provide data structures like vectors, lists, and maps. What specific container are you interested in?

I'm interested in vectors. How do I declare and initialize one?

You can declare a vector like this: std::vector<int> myVector;. To initialize it, you can use: std::vector<int> myVector = {1, 2, 3};.

How do I add elements to a vector?

You can add elements using the push_back method. For example: myVector.push_back(4); will add 4 to the end of the vector.

Can I remove elements from a vector?

Yes, you can remove elements using the pop_back method to remove the last element, or erase to remove a specific element.
