What are some common STL files used in C++?
In C++, the Standard Template Library (STL) includes several common headers like <vector>, <list>, <map>, and <set>. Each provides different data structures.
Can you explain what a vector is?
Sure! A vector is a dynamic array that can grow in size. It allows random access to elements and is part of the <vector> header.
What about maps? How do they work?
Maps are associative containers that store elements in key-value pairs. They allow for fast retrieval based on keys and are defined in the <map> header.
Are there any performance considerations I should be aware of?
Yes, different STL containers have varying performance characteristics. For example, vectors are fast for random access, while maps are efficient for lookups but may have overhead due to their underlying tree structure.
