What are some useful features of the C++ STL?

The C++ Standard Template Library (STL) offers several useful features, including containers like vectors and maps, algorithms for sorting and searching, and iterators for traversing data structures.

Can you explain how to use vectors in C++?

Sure! Vectors are dynamic arrays that can grow in size. You can declare a vector using std::vector<int> myVector; and add elements using myVector.push_back(value);.

What are iterators and how do they work?

Iterators are objects that allow you to traverse through the elements of a container. They provide a way to access elements without exposing the underlying structure. You can use begin() and end() methods to get iterators for a container.

What algorithms are available in the STL?

The STL provides a variety of algorithms, including sort(), find(), accumulate(), and copy(), which can be used with any container that supports iterators.
