What are the advantages of using generics in C++?

Generics in C++ allow for code reusability, type safety, and improved performance. They enable you to write functions and classes that work with any data type.

Can you give me an example of how generics improve code reusability?

Sure! With generics, you can create a single function that operates on different data types. For instance, a generic function to sort an array can sort integers, floats, or even custom objects without rewriting the code.

What about type safety? How does that work with generics?

Generics enforce type constraints at compile time, reducing runtime errors. This means that if you try to use a type that doesn't match the expected type, the compiler will catch the error before the program runs.

Are there any performance benefits to using generics?

Yes, generics can lead to better performance by eliminating the need for type casting and allowing for optimizations specific to the data type being used.

What are some common pitfalls when using generics in C++?

Common pitfalls include complexity in code readability, potential for code bloat due to multiple instantiations, and challenges with debugging generic code.
