How can I optimize data structures in C++?

How can I optimize data structures in C++?

To optimize data structures in C++, consider using the right container for your needs, like vectors for dynamic arrays or maps for key-value pairs.

What are the trade-offs between using a vector and a list?

Vectors provide fast random access and are cache-friendly, while lists allow for efficient insertions and deletions but have slower access times.

Can you give an example of when to use a map?

Use a map when you need to associate unique keys with values, like counting occurrences of words in a text.

How do I measure the performance of my data structures?

You can measure performance using time complexity analysis and profiling tools to identify bottlenecks in your code.
