How can I optimize my C++ code using templates?

You can optimize your C++ code by using templates to create generic functions and classes, which can reduce code duplication.

Can you give me an example of a template function?

Sure! Here's a simple 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 the performance benefits of using templates?

Templates can lead to better performance by enabling compile-time polymorphism, which can eliminate the overhead of virtual function calls.

Are there any downsides to using templates?

Yes, templates can increase compile times and lead to code bloat if overused, as each instantiation generates new code.
