Can you provide some examples of template programming?

Can you provide some examples of template programming?

Sure! Template programming allows you to write generic and reusable code. For example, in C++, you can create a template function like this:

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

This function can add integers, floats, or any other type.

What are some benefits of using templates?

Templates promote code reusability and type safety. They allow you to write a function or class once and use it with different data types without rewriting code.

Can you show me a template class example?

Absolutely! Here's a simple example of a template class in C++:

template <typename T>
class Box {
private:
    T item;
public:
    Box(T i) : item(i) {}
    T getItem() { return item; }
};

This class can hold any type of item.

Are templates only available in C++?

No, templates are not exclusive to C++. Other languages like Java (generics) and C# also support similar concepts for type safety and reusability.
