What is C++ template programming?

C++ template programming allows you to write generic and reusable code. It enables functions and classes to operate with any data type.

Can you give me an example of a template function?

Sure! Here's a simple example:

template <typename T>
T add(T a, T b) {
    return a + b;
}

This function can add two values of any type that supports the + operator.

What are the benefits of using templates?

Templates promote code reusability, reduce redundancy, and improve type safety. They also allow for better performance through compile-time optimizations.

Are there any downsides to using templates?

Yes, some downsides include increased compilation times and potentially more complex error messages. Additionally, misuse can lead to code bloat.
