What are the best practices for using containers in C++?

What are the best practices for using containers in C++?

When using containers in C++, consider the following best practices: choose the right container type, understand the performance implications, and use iterators for traversal.

Can you explain the differences between vector and list?

Sure! A vector is a dynamic array that provides fast random access, while a list is a doubly linked list that allows for efficient insertions and deletions.

How do I choose the right container for my needs?

To choose the right container, consider factors like the type of operations you'll perform (insertion, deletion, access), the size of the data, and performance requirements.

What are some common pitfalls to avoid?

Common pitfalls include using the wrong container for your needs, not considering the overhead of copying elements, and failing to reserve space in vectors.
