C++ STL vs Custom Implementations: Which Should I Use?

What are the main differences between C++ STL and custom implementations?

C++ STL (Standard Template Library) provides a set of ready-to-use data structures and algorithms, while custom implementations are tailored solutions that you create for specific needs.

When should I prefer using STL over custom implementations?

You should prefer STL when you need quick development, reliability, and performance for common data structures. Custom implementations are better for specialized needs.

Can you give an example of when a custom implementation is necessary?

Sure! If you're working with a unique data structure that requires specific performance optimizations or behaviors not provided by STL, a custom implementation would be necessary.

Are there any performance trade-offs between using STL and custom implementations?

Yes, STL is highly optimized for general use, but custom implementations can be optimized for specific scenarios, potentially offering better performance.
