Can templates be used with classes and functions?

Can I use templates with classes in C++?

Yes, you can use templates with classes in C++. This allows you to create a class that can operate with any data type.

What about functions? Can templates be used there too?

Absolutely! Function templates allow you to create a function that can work with different data types without rewriting code.

Can you give me an example of a function template?

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.

Are there any limitations to using templates?

Yes, templates can lead to code bloat if overused, and debugging template errors can be more complex than regular code.
