What are some common use cases for templates in C++?

Templates in C++ are often used for creating generic functions and classes. This allows for code reusability and type safety.

Can you give me an example of a template function?

Sure! A common example is a template function for finding the maximum of two values:

template <typename T>
T getMax(T a, T b) {
    return (a > b) ? a : b;
}

What about template classes?

Template classes allow you to create a class that can operate with any data type. For example, a simple stack class can be templated to hold any type of data.

Are there any performance benefits to using templates?

Yes, templates can lead to better performance because they allow for compile-time polymorphism, reducing the overhead of virtual functions.
