How do I catch exceptions in C++11?

Can you explain how to catch exceptions in C++11?

Sure! In C++11, you can catch exceptions using the try-catch block. You wrap the code that might throw an exception in a try block and handle the exception in the catch block.

What types of exceptions can I catch?

You can catch standard exceptions like std::runtime_error, std::logic_error, and any user-defined exceptions. You can also catch all exceptions using a catch-all handler.

Can you show me a code example?

Of course! 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, it will propagate up the call stack. If it reaches the main function without being caught, the program will terminate.
