Can you give me some examples of try-catch in C++?

Sure! In C++, the try-catch block is used to handle exceptions. Here's a simple example:

#include <iostream>
#include <stdexcept>

int main() {
    try {
        throw std::runtime_error("An error occurred");
    } catch (const std::runtime_error& e) {
        std::cout << "Caught: " << e.what() << std::endl;
    }
    return 0;
}

What happens if I don't catch an exception?

If you don't catch an exception, the program will terminate and display an error message. It's important to handle exceptions to prevent crashes.

Can I have multiple catch blocks?

Yes, you can have multiple catch blocks to handle different types of exceptions. Here's an example:

try {
    // code that may throw exceptions
} catch (const std::runtime_error& e) {
    // handle runtime_error
} catch (const std::exception& e) {
    // handle any other exception
}

Are there any best practices for using try-catch?

Yes, some best practices include:

1. Only use try-catch for exceptional cases, not for regular control flow.
2. Catch specific exceptions rather than using a general catch.
3. Keep the try block small to avoid catching unintended exceptions.
