How do templates and exceptions work in C++?

How do templates and exceptions work in C++?

Templates in C++ allow you to write generic and reusable code. Exceptions are used for error handling.

Can you give me an example of a template function that uses exceptions?

Sure! Here's a simple example:

template <typename T>
T safeDivide(T numerator, T denominator) {
    if (denominator == 0) {
        throw std::invalid_argument("Denominator cannot be zero.");
    }
    return numerator / denominator;
}

What happens if I don't handle the exception?

If you don't handle the exception, your program will terminate and display an error message.

Are there best practices for using templates and exceptions together?

Yes, it's best to keep your templates simple and ensure that exceptions are used for exceptional cases only.
