What are the best practices for using templates in C++?

When using templates in C++, it's important to keep them simple and avoid unnecessary complexity. Use clear naming conventions and document your templates well.

Can you give an example of a simple template?

Sure! Here's a basic example of a template function that swaps two values:

template <typename T>
void swap(T& a, T& b) {
    T temp = a;
    a = b;
    b = temp;
}

What are some common pitfalls to avoid with templates?

Common pitfalls include excessive template specialization, overusing template metaprogramming, and not considering compilation times.

How can I improve compile times when using templates?

To improve compile times, minimize the use of templates in header files, use forward declarations, and consider using explicit instantiation.
