What are template functions in C++?

What are template functions in C++?

Template functions in C++ allow you to write generic and reusable code. They enable functions 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 integers, floats, or any other type that supports the '+' operator.

What are the benefits of using template functions?

The main benefits include code reusability, type safety, and the ability to work with different data types without code duplication.

Are there any drawbacks to using template functions?

Yes, some drawbacks include longer compile times and potential code bloat, as each instantiation creates a new version of the function.
