What are the trade-offs in C++ optimization?

In C++, optimization can improve performance but may increase complexity and reduce code readability. What specific area are you interested in?

I'm curious about the impact on memory usage.

Optimizing for speed often increases memory usage, as techniques like caching and pre-computation require additional space. Would you like examples?

Yes, please provide some examples of such optimizations.

One example is using data structures like hash tables for faster access, which can consume more memory compared to simpler structures. Another is loop unrolling, which can speed up execution but may increase code size.

How do I decide when to optimize?

It's best to optimize when you identify performance bottlenecks through profiling. Focus on critical sections of code that impact overall performance.
