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 two numbers of any type.

How do template functions differ from regular functions?

Template functions are defined with a template parameter, allowing them to work with any data type, while regular functions are type-specific.

Are there any limitations to using template functions?

Yes, template functions can lead to code bloat if overused, and they may result in longer compile times due to type instantiation.
