What are the best practices for using the C++ STL?

When using the C++ Standard Template Library (STL), it's important to follow best practices like using appropriate containers, understanding iterators, and avoiding unnecessary copies.

Can you explain why choosing the right container is important?

Choosing the right container affects performance and memory usage. For example, using a vector for dynamic arrays is efficient, while a list is better for frequent insertions and deletions.

What are some common pitfalls to avoid?

Common pitfalls include using the wrong container for the task, not considering the complexity of operations, and failing to manage memory properly.

How can I improve my STL code performance?

To improve performance, minimize copies by using references, prefer algorithms that work with iterators, and utilize move semantics when possible.
