STL Containers vs Arrays: Which Should I Use?

What are the main differences between STL containers and arrays?

STL containers like vectors and lists offer dynamic sizing and built-in functions, while arrays are fixed-size and simpler.

When should I prefer using STL containers over arrays?

Use STL containers when you need flexibility, like dynamic resizing or advanced operations. Arrays are better for fixed-size data.

Can you give examples of when to use a vector instead of an array?

Sure! Use a vector when you need to frequently add or remove elements, or when the size of the data is not known at compile time.

Are there any performance differences between them?

Yes, arrays can be faster for simple access due to less overhead, but STL containers provide better performance for complex operations.
