How does template programming work?

Can you explain how template programming works?

Template programming is a technique in programming that allows functions and classes to operate with generic types. It enables code reusability and type safety.

What are the benefits of using template programming?

The main benefits include code reusability, type safety, and the ability to create flexible and efficient algorithms that can work with any data type.

Can you give me an example of template programming in C++?

Sure! In C++, you can define a template function like this:

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

This function can add two numbers of any type, such as integers or floats.

Are there any downsides to using templates?

Yes, some downsides include increased compilation times and potential code bloat, as templates can lead to multiple instantiations of the same code for different types.
